Exit car diagnostics as a business. How to start an on-site auto diagnostics business

Buying a used used car is a real problem for car enthusiasts. Not everyone has enough experience to properly assess the condition of the car when buying. Therefore, specialists who are able to present the conclusion of an expert review will always be in demand.

How to start a business based on car diagnostics?

A modern car is a complex technical device. It is possible to determine its true state only with special knowledge and experience, especially if you are not buying a new car, but with a used one. Many sellers give the car a polish and forget to clarify that the car has been in an accident or that the engine has been moved. A company specializing in car diagnostics provides technical assistance to buyers of used cars.

Business organization

To open a business such as car diagnostics, you need to register an individual entrepreneur. This is enough to provide pre-purchase assessment services.

It's great if there is an opportunity to purchase diagnostic equipment. In particular, you will need:

A device for determining the thickness of the coating - 7-10 thousand rubles;

Scanner for computer diagnostics of electronic systems - 50-100 thousand rubles.

It is also necessary to rent a room with a lift - from 10 thousand rubles a month in a small town and much more in a metropolis.

But you can start with minimal costs. For example, to purchase not new, but used diagnostic equipment.

There are no special requirements for the organization. You can go for checks in a place convenient for the client. But still, in order to properly diagnose a car, it is necessary to raise it on a lift and check in detail the suspension, exhaust and brake systems, and so on.

Business payback

The cost of diagnosing the condition of one car is on average from 3 thousand rubles. If you buy new equipment and rent a room, then the initial investment will be approximately 70 - 130 thousand rubles. To attract customers, you can create a website and distribute flyers in places where potential car customers congregate. In the first months there will be few orders, but even if one diagnostics is carried out every two days, the investment will pay off in two to three months. The profitability of a business based on car diagnostics can be as high as 35%.

Business plan for organizing a post for diagnostics and repair of electronic systems of cars

1. Objectives of the project

In the previous chapters of the work, an analysis of the state of the enterprise "Avtodom-Ateks" was made and, on the basis of this analysis, recommendations on the development strategy were given. Diversification seems to be the most attractive strategy.

Now it is necessary to determine: which of the areas of activity should be developed in the first place? The answer is obvious: it is necessary to develop a range of services for the diagnosis and repair of electronic systems in cars. The reasons for this decision are as follows:

· This service is more and more in demand in the market;

· Our regular customers will willingly use this service with us;

· This will allow attracting new customers both for this service and for the entire range of services provided by the enterprise;

· Work with electronic systems fit well into the general profile of the enterprise;

· The personnel of the enterprise has a sufficiently high level of qualification, only minimal training is required;

· The enterprise has the opportunity to rent production areas for the placement of a post for diagnostics and repair of electronic systems of cars.

The planning horizon for the implementation of the project will be taken as the average for this type of activity, that is, 3 years. The start date of the project is 01.06.2006.

2. Description of the type of activity

In general, it is not difficult to eliminate this or that malfunction in the car. And, as a rule, for a relatively short time. This statement, however, is true only when three conditions are met: it is known how, what and what exactly needs to be done. If, as a rule, problems never arise with the first two, then the third often becomes a real stumbling block. First of all, this concerns the problems associated with the engine and various electronic systems, with which modern cars are stuffed, as they say, to the very roof. Thus, the correct identification of the causes of failures and malfunctions has come to the fore today, which gives us the right to speak even about a new specialty in a car service - a diagnostician. The sharp increase in the number of vehicles equipped with electronic fuel injection systems has led to a tangible increase in demand for services related to the diagnosis of the technical condition and repair of such vehicles.

First of all, especially careful diagnostics are required by engine management systems (ECS). The technical condition of the vehicle engine management system is one of the most important factors affecting the traction and speed performance of the vehicle as a whole. A practical solution to the problem of diagnosing the technical condition and repairing the VMS is impossible without the use of special technical means, most of which are measuring instruments.

You can create all kinds of puzzles for yourself out of the blue, then strain your mind in search of answers and suffer for a long time trying to solve the problem, which diagnostic device should be preferred. Or you can follow a simpler and more natural path. It is easy to understand exactly what devices for diagnosing the engine and its systems exist today and what exactly can be found with their help. And also understand that a complete set of equipment is needed to fully diagnose the engine. And having understood this, make the configuration that best suits one or another specific needs.

3. Necessary equipment and its selection

Firstly, all equipment for engine diagnostics can be divided into several groups, each of which performs its own range of tasks. You can define these groups like this:

1) Scanners of control units;

2) Measuring instruments;

3) Testers of executive devices and engine units.

The first group of devices is a set of devices designed to establish communication with control units of vehicles and perform such procedures as reading and erasing errors, reading current values of sensors and internal parameters of the control system, checking the operability of actuators, adapting the control system when replacing individual vehicle units or during capital repair of the engine. This group of diagnostic devices is developing very dynamically and every year brings new possibilities of scanners and new names of their manufacturers. In principle, scanners can be compared with each other in terms of such parameters as a table of applicability by car type and a list of automotive systems, a set of functions implemented in the scanner for each vehicle or system, and a method of software upgrading. In combination with the price of the devices, you can compile a comparison table that will give a rough idea of whether or not to purchase a given scanner model.
Why an approximate match, you ask? Because the companies that make scanners do not have direct contact with car manufacturers and, therefore, out of 10 car models of a given year of manufacture, one or two can always come across, which were missed when designing the scanner - the manufacturer learns about this only from end customers or does not know at all ... In addition, buyers of diagnostic equipment can often suffer from the fact that the managers of the equipment selling firms do not have sufficient information about the subject of the bargain and replace it with their own eloquence.

According to the estimates of a number of car services that are actively engaged in diagnostics, it is economically impractical to have a set of scanners for all vehicles with advanced capabilities (up to adaptation), and in the absence of properly trained personnel, it is also dangerous - incorrect actions when interfering with the operation of the unit can lead to a deterioration in the operation of the system engine management and, as a result, cause unnecessary problems in the relationship with the client. When choosing scanner models, one should take into account the specialization of the service and the list of the most frequently serviced models (for example, if one Fiat car comes to you a year, then it is hardly advisable to purchase a scanner specifically for its service).

In addition, you can have one or two scanners with an average set of functions, but with a wide range of car models - in this case, in most cases, you solve the assigned tasks, and you compensate for the functional shortcomings of the scanners with the help of universal equipment from the second and third groups.

In the second group collected devices that can be used to diagnose any engines - the physics of the engine does not depend on the control method. All these devices are used to detect malfunctions, as well as to check the readings of scanners, since no electronic system can check itself with absolute certainty - for example, an air leak in the intake manifold can cause an air flow meter failure message, etc. In the absence of the devices listed below, you often make a decision to replace one or another sensor without proper verification and may subsequently find yourself in a scandalous situation in which, as you know, there are no winners. The most famous representatives of this group:

Gas analyzers.

Gas analyzers and opacimeters. The general picture of the technical condition of any internal combustion engine can be obtained by analyzing the exhaust gases. When the fuel-air mixture burns, various chemicals are formed in the engine cylinders. These are CO, NOX, CH, O2 and some others. Analysis of the percentage of each of these compounds in the exhaust gases allows you to judge the working processes occurring in the engine and identify the causes of deviations from the norm. The method of assessing the health of the engine by the quality of the exhaust gases is a topic for a separate conversation, but now we will only talk about the devices that perform this check.

Since gasoline and diesel engines use different types of fuel, different components are formed in the exhaust gases, different devices are used to check them: a gas analyzer for gasoline engines and an opacimeter for diesel engines.

The functionality of the gas analyzer is determined by the number of measured parameters. Recently, measurements of the two main gases CO and CH have become insufficient for high-quality engine diagnostics, the latest generation gas analyzers are four-component (CO, NOX, CH and O2) with a calculated coefficient l (lambda). The coefficient l is a relative value and shows the ratio of fuel and air in the working mixture. Some models of gas analyzers can measure the voltage in the vehicle's on-board network, temperature, and so on.

Most gas analyzers are designed as stand-alone devices and display the measurement results on a digital display. Also, many models may have a built-in printing device. More recently, models have appeared that allow you to display the measurement results on a personal computer. This allows you to present information in the form of graphs and diagrams, and the connection of a scanner, a motor tester and a gas analyzer to one PC makes such a complex an excellent tool for car diagnostics.

As already mentioned, the analysis of exhaust gases shows only a general picture of the state of the engine; a scanner and a motor tester, designed to check individual engine systems, allow to identify the specific culprit of the malfunction.

Meterspressure.

In this group of devices, one representative of which - a compressometer - has long been loved by all car services, there is a significant addition. First of all, this is a fuel pressure tester, which was not in car services designed for the repair of carburetor cars. The main characteristics of this device are the range of the measured pressure (usually it ranges from 0 to 6..8 bar) and the list of adapter fittings for connecting to the fuel systems of various vehicles. Also, a valve-piston group leak tester has become very popular, which makes it possible to more accurately determine the place and nature of the leakage of the combustion chamber in comparison with a compression meter, a vacuum gauge, which allows assessing the correct operation of the engine intake system, and a catalyst backpressure tester, which makes it possible to assess the catalyst throughput.

Specialized automotive testers.

When repairing contact ignition systems, a specialized automotive tester was often sufficient to find faults in this system. With the predominance of electronic ignition systems, its capabilities for their diagnostics are clearly insufficient; automotive oscilloscopes and motor testers, which have much greater capabilities in comparison with it, come to the fore.

Stroboscopes.

Although installation of ignition is not possible in most injection engines, test values for ignition systems still exist and timely determination of the discrepancy between the calculated and actual ignition timing often helps to determine the nature of the malfunction. But to check the ignition timing in injection engines, it is necessary to use stroboscopes equipped with a flash delay adjustment, since these engines usually do not have a separate mark for setting the ignition timing.

Specialized automotive oscilloscopes.

These devices have a set of specialized sensors (high voltage, vacuum, current) and a special synchronization system with the rotation of the engine using the current sensor of the spark plug of the first cylinder. which allows you to diagnose the engine management system for any parameters. At the same time, they retain the capabilities of a universal oscilloscope and, therefore, can be used to test the operation of almost all electrical circuits of a car. In addition, they can replace a number of individual devices used for diagnostics - for example, if you have a vacuum sensor in your automotive oscilloscope, you no longer need to purchase a vacuum gauge.

Motor testers.

The measuring part of the motor tester is basically the same as the measuring part of the car oscilloscope. The difference between motor testers is that it can not only display oscillograms of any measured circuits, but also make comprehensive assessments of the engine's operation by several parameters at once (dynamic compression, acceleration, comparative cylinder efficiency, etc.), which makes it possible to significantly reduce the time for troubleshooting. When purchasing equipment, it is also necessary to take into account that devices such as a gas analyzer, stroboscope, etc. are often an integral part of motor testers. - therefore, although the price of a motor tester is quite high, when buying it, the total losses will be relatively small compared to purchasing a separate automotive oscilloscope, gas analyzer and stroboscope.

The third group of devices is equipment for in-depth testing of the engine management system and its individual components. It includes:

Sensor signal simulators.

Designed to check the unit's response to changes in the signals of individual sensors (for example, temperature sensors or throttle position) - in some cases, the control unit may not respond to a change in the signal from the sensor, and this fact can be perceived as a sensor failure.

Injector tester.

At the initial stage of the development of diagnostics, such devices were quite actively sold on the market, but recently, preference is given to stands for cleaning and checking injectors - they include checking, and if necessary, cleaning the injectors can be carried out more efficiently. In addition, these stands by themselves create a separate set of paid services, the return on which is increasing every year.

Vacuum pump.

This device allows you to check the operability of the actuators actuated by the vacuum in the intake manifold (for example, the afterburner valve or the purge valve of the catalyst), as well as to check the vacuum sensor in the intake manifold with the engine stopped.

Spark plug tester.

Allows you to visually check the operation of spark plugs without installing them on the engine. Some testers have the ability to test the spark plug under pressure, i.e. in conditions close to real.

High voltage arrester.

These devices allow you to check the operation of the car ignition system for a load that is close to real. For ignition systems with a mechanical distributor, a spark gap with an air gap of 10 mm is used, for modern ignition systems without a distributor - 20-21 mm.

So, we decided to engage in diagnostics and repairs. Based on the foregoing, we will allow ourselves to give several recommendations for completing the diagnostic post and some rules that must be followed in diagnostic work.

Simplest solution.

First of all, the most necessary device is a gas analyzer, and the best of all is a four-component one with a calculated lambda coefficient (l). Diagnostics of the engine, as the main unit of the car, without this device is simply impossible. By choosing a model with the possibility of electrical measurements, you slightly overlap the capabilities of the motor tester. The fuel pressure gauge and pressure gauge are quite inexpensive, but nice little things in the diagnostician's kit. The simplest installation for flushing injectors will be of great help when you encounter cases of poor quality of the working mixture in the vehicles being examined.

Mobile or stationary post.

The next question is which diagnostic post is more preferable for us: stationary or mobile?

If we equip a diagnostic post at a service station, then we need to pay attention to the possibility of completing the equipment around a personal computer (PC). This will make it possible to create a single diagnostic complex from the scanner, motor tester and gas analyzer with the ability to update the software. In addition, the PC can contain a huge database of serviced vehicles, which in itself is a huge help in the work.

If you intend to carry out field work (technical assistance on the road), then you need to pay attention to the possibility of operating the devices from the vehicle's on-board network. While using a laptop, you can keep mobility and take advantage of the above advantages of a PC.

The variety of cars and their age impose certain restrictions on the choice of equipment. First of all, this concerns the choice of a scanner. As mentioned above, the scanner is rigidly tied to the make of the car, even the year of manufacture of the car and the brand of the "on-board computer" can affect the quality and the possibility or impossibility of diagnostics as such. When choosing a scanner, the main focus is on the list of brands and years of production of cars that the scanner supports, a set of cables for connecting to the vehicle's control connector, and the ability to change the scanner software to expand its capabilities. I would like to once again draw your attention to scanners that work with a personal computer - the PC has almost unlimited possibilities for updating the software, and if necessary, you only need an additional cable.

In addition to the listed devices, for the effective operation of the post being created, it is required to purchase:

· Two-post lift with a lifting capacity of 2500 kg. for cars - 1 pc .;

· Transmission racks with a loading capacity of 300 kg. - 2 pcs.;

· Rolling jack with a lifting capacity of 2000 kg. - 1 PC.;

· Charging and starting device - 1 pc .;

Locksmith workbenches - 2 pcs .;

· A set of hand tools.

The market overview of the equipment offered for sale showed the following. Sales of the equipment we are interested in, its installation, maintenance and repair, as well as personnel training and technical support are carried out by the five largest companies:

· "Am-Euro";

· "Barclay-Auto";

· "Diakom-Auto";

· "Diamax holding";

· "Novgorod plant GARO".

On the basis of a long and painstaking study of the commercial proposals of these companies, a decision was made to cooperate with Diamax Holding. It is located at:

For the convenience of calculations, the resulting amount will be rounded up to 400,000 rubles. Depreciation of the equipment will be calculated on the basis that the residual value is reduced by 50% over three years. Monthly, respectively, it turns out 1.4%, or 5600 rubles.

The equipment layout plan is now being developed. The post has the ability to work with two vehicles at the same time. That is, the diagnostic and repair post will have two parking spaces. The total area is 50 sq. m. This means a 20% increase in existing production areas. Rent 70 rubles / sq. m / month, or 3500 rubles per month for the planned area.

The costs of maintaining and maintaining the rented premises will add 20% or 2,000 rubles per month to the existing expenses of the enterprise under this item.

4. Personnel

equipment engine car staff

The main purpose of car diagnostics is to find and detect a faulty vehicle system and engine, in particular. Often the restoration of contact in the circuit of one or another sensor prevents "overhaul" of the engine, therefore, the quality of diagnostics primarily depends on the person, on the diagnostician. The client's reaction also depends on him. Therefore, you should first learn all the intricacies of the process. For this, there are special courses, when choosing which you need to pay attention to the following:

• training should be provided by adequately trained mentors;

· The training program should include theoretical issues of the operation of all vehicle systems and subsystems of the internal combustion engine (nodes, sensors, actuators, etc.);

· Practical exercises, as an integral part of the program, should be conducted in the real conditions of a car service station and, best of all, using the equipment on which you will work in the future.

When buying equipment, do not hesitate to ask the seller about the availability of such preparatory courses - only those companies that take this area of activity seriously can provide training of specialists and further support. And most importantly, we must not forget that quickly and correctly carried out diagnostics, the ability to accurately catch the "culprit" of the car owner's problems can only contribute to the growth of the company's authority and, as a result, to an increase in the number of grateful clientele.

Therefore, it was decided to train the two most qualified employees and transfer them to this type of activity. An additional 2 people will be hired to replace them. Which will lead to an increase in the imputed tax on the enterprise as a whole. These costs can be safely attributed to the unit being created.

The situation for training courses is about the same as for equipment. A decision is made to train two employees at the Diamax Holding courses. The cost of training will be 10,000 rubles.

The salary of production personnel is piecework and is 40% of the amount paid by the client for the work performed. It is calculated according to the “Work” column in the “Order for work with a car” form.

What is an on-site autodiagnostics

Almost every vehicle owner was faced with a situation when, while driving a car, a red icon appeared on the dashboard, signaling an error in the car. In this case, it is necessary to urgently contact a car service, but the car is not always safe to drive.

An error may occur, in which the car cannot move further, so the solution to the problem can be solved in two ways:

calling a tow truck, accompanied by the transportation of the car to a service or to a parking lot, and for this service you have to pay significant funds;
contacting a company that provides an on-site car diagnostics service, which will allow on the spot to determine the cause of the problem in the vehicle with minimal waste of money and time.

Important! To open this case, you will need specialized equipment with a long service life and ease of use, so if you understand the rules for working with it, you will ensure high-quality provision of services.

Often, the business idea of on-site diagnostics is combined with a stationary diagnostic center. In this case, the opening of such an institution will require quite significant investments, often exceeding even 500 thousand rubles.

List of possible services

High-quality diagnostic equipment allows a business owner to provide several services to potential customers at once:

body inspection, which usually takes a long time, and it is this service that is the most expensive;
vehicle interior check;
diagnostics of its engine;
study of the electronic system, for which a specialized scanner is used;
brake system diagnostics;
studying the chassis of the car using an external examination;
testing a car in road conditions.

Important! To provide these services, it is necessary that the staff has a qualified and experienced specialist who knows how to work with equipment, as well as who is well versed in the device and features of repairing cars of different brands.

Necessary equipment

To work in this field of activity, it is necessary to purchase high-quality and reliable equipment. It is considered quite simple and inexpensive, but it is important to carefully study all the rules for working with it. For on-site car diagnostics you need:

a mobile scanner, which is a universal equipment, and its price varies from 50 to 90 thousand rubles;
a thickness gauge that allows you to determine the thickness of the paintwork on any part of the car, and its cost starts from 10 thousand rubles;
a laptop in which a specialized program must be installed that decrypts various fault codes on different brands of vehicles;
adapter for connecting the car to the computer.

Important! The diagnostic software must be purchased so that you can enjoy all its advantages, and regular updates are also required, and usually this costs up to 5 thousand rubles a month.

How is the order going

The work of this organization is carried out in a certain sequence of actions:

Stage 1

Initially, it is necessary to advertise the organization in different ways so that as many potential customers as possible know about it. It is important to focus on the professionalism of the organization's employees, as well as on the high quality of the equipment used for work.

Stage 2

Clients call the phone number indicated in the advertisements to order services. The manager, who is always in the office, accepts applications. It is important during a telephone conversation to find out what the model and brand of the car is, as well as where it is located. This information will allow you to determine in advance where in the vehicle the connector is located, thanks to which it can be connected to a computer for diagnostics.

Stage 3

An employee of the organization travels to the specified address, where the diagnostic service is provided. For this, a special chip is connected to the vehicle connector. You need to go to the program installed on the computer to carry out the procedure. At its end, information will be displayed on the computer screen about the reason for the error, as well as what needs to be done to repair the vehicle.

Stage 4

The customer receives information from the company's employee about the existing malfunctions in the car, after which he pays for the call of a specialist. Usually, the whole diagnostic process does not take more than 3 minutes, after which a company employee can go to the next call.

Working according to this scheme, the organization can receive daily proceeds in the amount of 3 thousand rubles. from each employee.

Advertising and customer search

An important point of effective work is high-quality business promotion, and various methods can be used for this:

Promotion method	Its features
Word of mouth	The most effective method, however, does not depend in any way on the actions of the company. If really high-quality, effective and inexpensive services are provided, then customers will advise the company to their friends and acquaintances, which significantly increases the number of potential customers.
Social media	If you use the power of social networks correctly, a huge number of clients can be attracted. You can promote yourself or with the help of a hired specialist.
Creation of your site	Modern people prefer to find the services and goods they need using the Internet, so having their own electronic resource on which information about a company and its services is located can attract many customers.
Placement of ads in different media	The traditional way to promote effective business development.

Thus, for the development of the company, it is allowed to use several promotion methods at once.

Financial expenses

It takes 112 thousand rubles to open a business:

purchase of equipment - 70,000;
advertising expenses - 40,000;
business registration - 2,000.

To this must be added the costs of writing a business plan for an on-site autodiagnostics, which will become the "cornerstone" of the entire business. By this link, you can find a business plan for organizing a full-fledged car service, and

On-site car diagnostics is a profitable and non-standard business. The foundation of this direction is laid in the development of the secondary market for the sale of cars. Often, one car even has up to 4 owners. And in order to solve many questions, buyers-sellers prefer to use paid diagnostics right on the spot. After all, frank scrap metal can have a fresh, painted and attractive appearance. Therefore, the demand for car diagnostics is always stable and high.

This is a promising area for a budding entrepreneur. The main advantage of this type of business is considered to be a small investment in investments and ease of running a direction. Separately, I would like to emphasize the low competition in this industry. But, it is important to understand cars and have some practical skills in car repair.

Choosing an office.

Even a business based on onsite car diagnostics needs to have an address. And for this it is necessary to rent at least a small room. An office with an area of about 30 square meters will be enough for work. It can be like the first floor of an apartment building, transferred to a non-residential fund and with a separate entrance from the street. Or a rented office in a business center. The room does not play a special role. However, it must be fully prepared to welcome its visitors at all times. In the room, it will be necessary to equip working areas for personnel.

The cost of rental services depends on the territorial location of the premises and costs about $ 300-500.

Necessary equipment.

1. Computer or tablet - from $ 300;
2. Adapter (required to connect the machine to the computer equipment connector) - from $ 80;
3. Mobile auto-scanner (reads codes from the engine and issues a report with a list of errors and malfunctions) - from $ 1 thousand;
4. Computer program (is the "key" in determining the nature of malfunctions for different types of cars) - from $ 700;
5. Portable thickness gauge of coatings (for determining the condition of the car's coating, detecting traces of dyeing) - from $ 1.5 thousand.

It is worth noting that many young businessmen start making mistakes when deciding to purchase inexpensive equipment from Chinese sites. Yes, the savings are significant, but how well the product will perform the work is an important question. Therefore, it is better to turn only to trusted brands and purchase only high-quality software equipment.

The license will allow you to use regular updates. Moreover, the number of car brands is growing every year. Updates will not be free. In addition, it is worth adding about $ 25-30.

In total, about $ 5.5 thousand are allocated for the purchase of the necessary equipment.

Staff.

Business alone will not work. Assistants are needed: a manager, an experienced car mechanic. The team will not be big - 2-3 people. With the development of the business, the staff can be expanded. The manager's responsibilities will include working with clients, processing requests, drawing up and adjusting the schedule, as well as activities aimed at increasing the number of requests from potential clients. A car mechanic, as a person with experience, will have to accompany each exit. The employer sets the salary independently.

You should count on the amount of at least $ 1.6 thousand.

It is on advertising that the success of the company will be based. Here you need to approach in a multifaceted way, using both traditional and the latest methods of influencing buyers. Business will help the creation of its own website, print ads in popular newspapers and magazines, advertising in specialized print media.

Special attention should be paid to the promotion and quality of your own site. You can place outdoor advertising in the vicinity of a service station or not far from gas stations. Another important point in business development is the exchange of information. When carrying out diagnostics, you can advise consumers on one of the services. The car repair company itself will advise your business. Thus, you can negotiate mutually beneficial advertising.

About $ 1,000 is allocated for marketing.

Basic expenses.

A business based on on-site car diagnostics will have the following cost items:

1. Rent of premises - $ 300-500;
2. Purchase of equipment - from $ 5.5 thousand;
3. Personnel - from $ 1.6 thousand;
4. Advertising - $ 1,000.

In total, about $ 8 thousand is needed to create this type of activity.

Profit and return on investment.

The average price of on-site car diagnostics is about $ 70-100. One procedure takes about an hour. It is also worth always counting on travel time. In one day, the master can take about 5 cars. This means that one specialist can earn up to $ 500 per day. The work schedule will be busy and you will often have to work in the evenings. Nevertheless, the monthly income will be from 2 to 6 thousand $ at full workload.

Thus, the business can be recouped in 2-3 months.

Clients and development options.

The potential audience of clients is more than wide - they are people of different ages with any income level. The development options are geared towards the automotive business. So, you can promote the sale of cars and hire craftsmen to perform some kind of repair work.

Every person with a computer wants to put it to good use. Usually, the greatest income is obtained at the junction of different areas of human activity. I'll tell you about a great way to have a good and constant income using a computer in a car service.

COMPUTER DIAGNOSTICS of injection engines VAZ, GAZ and foreign cars;
CHIP-TUNING for injection VAZs and foreign cars;
RUNNING ADJUSTMENT on the electronic odometer of VAZ and foreign cars.
COMPUTER DIAGNOSTICS.

Modern cars are injection vehicles. What it is? This means that the engine is controlled by an electronic control unit (ECU). Injection engines are still a novelty for our car service, especially in the regions. Diagnosing and repairing such an engine is a challenge. There are special scanners that are very expensive (about $ 1000), or a computer program that costs a penny. The possibility of earning money is obvious. You could provide injection engine diagnostics services in your city.

What is required for this?

1) a computer, preferably a laptop - 15,000 rubles;

2) an adapter (k-line) for connecting a car to a personal computer (it can be easily assembled in 10 minutes, slowly) - parts for 200 rubles, or;

3) a computer program for diagnostics of injection engines;

4) garage, it is better to negotiate with a practicing auto mechanic with his garage (as I did), besides, he could eliminate found faults, has a circle of his clients ...

5) some free time, I do this evening after work.

Total costs are about 20 thousand rubles. If you already have a computer, then the costs are about 1200 rubles, excluding advertising costs.

Diagnostics of an injection car, without any repairs in Togliatti, costs 200-800 rubles (if you live on the periphery, you can raise the price even higher). It is easy to calculate that if one car arrives per day, then your profit per month will be 6 thousand rubles.

CHIP TUNING. What's this? The operation of the injection engine is controlled by an electronic control unit (ECU). The control unit contains the program of its work. The control unit, receiving signals from various sensors, controls the operation of the engine. By changing the control program, we can influence its work. This is called chip tuning.

What can be achieved with chip tuning?

1) Improved dynamics and engine power: you want the car to pull confidently from the bottom. The corresponding program, with a certain increase in power, will provide a higher torque in the zone of low and high revs (acceleration dynamics). Good solution for city traffic.

2) Exclusion of the catalytic converter: if the vehicle is equipped with a catalytic converter, there is always a risk of poisoning the catalytic converter and oxygen sensor with leaded gasoline. You can exclude the catalyst, and then leaded gasoline will not be scary to the injection system. At the same time, an increase in engine power is observed.

3) Elimination of floating faults: they looked at the car at the services and could not find the cause of the engine periodically stalling at idle, or the CHECK ENGINE lamp that lights up when the engine warms up, with outwardly normal engine operation? The reason may lie in program errors. Often such problems are solved by replacing the old serial program with a new one.

In almost all tuning versions, the idle and cold start modes have been improved, the temperature at which the cooling system fan has been switched on has been reduced (for those who are "boiling"), the identified errors that were present in the old production versions have been eliminated.

Again, there is a good opportunity to make good money by providing this service.

Expenses:

already mentioned: computer and adapter (k-line);
chip programmer - $ 120;
microcircuits 27C2S6, 27CS12 and panels (for a start, pieces of 5) - 35 rubles each;
adapter for loading the control program (firmware) into the ECU (a very simple and accessible circuit for self-assembly) - parts per 100 rubles;
the program is a loader of firmware in the ECU and the firmware itself (control programs).

In total, in addition to the above (it is assumed that a computer and an adapter (k-line) are already available) about 5 thousand rubles.

The payback is very fast: chip tuning costs from 1000 rubles on average; and those who want to ride not like everyone else (sports acceleration dynamics) among the owners of injection 99-current, 10-current, and 15-shek is enough.

TRAVEL ADJUSTMENT. Leaving the ethical side of odometer adjustments alone, odometers have been twisted or twisted since they were invented. Currently, three types of dashboards with an electronic odometer are used on VAZ front-wheel drive vehicles. In simplified form, the odometer in these systems is a counter of impulses received from the vehicle speed sensor, a divider and an information storage device in the flash memory of the panel. There is a computer program to change the odometer reading. It allows you to quickly and easily adjust the mileage. The program works through a special adapter (very simple, 30 rubles for details). The cost of this complex is minimal, and the income from its use is very high. The cost of correcting the mileage of the VAZ electronic odometer is 500-600 rubles. Payback occurs in 2-3 uses.

ONCE A FEW THOUGHTS.

1. If you have never dealt with cars before, then it is highly advisable to find yourself a companion, a practicing auto mechanic (as I did). There are a lot of advantages in this. First, you have a representative office and a place to work (I have a simple garage). Secondly, there is a complementarity. There are very few auto mechanics among computer scientists and vice versa. And both are the winners. Thirdly, his clients immediately become yours, and you start attracting new ones to him (mutual promotion), etc. etc…

2. These services are focused on modern domestic injection vehicles and complement each other. This allows you to get additional profit. For example, if a car comes to you for diagnostics, then it is very likely that the car owner will be interested in chip tuning and mileage adjustment.

3. This business is not widespread and, having mastered it, you, most likely, will not have competitors.

4. Injection vehicles are becoming more and more every year, and now there are already plenty of them. And this tendency will only grow stronger. For example, the VAZ 2110 has been produced only in injection for more than a year.

5. It does not take much time and you can work in the evening after work. It takes me on average 1-2 hours a day and brings 500-2000 thousand rubles a day! (city of about 50 thousand inhabitants). The larger the city, the higher the profit.

6. You get a new circle of acquaintances and, most likely, very wide. New acquaintances -> new information -> new opportunities. It is difficult to overestimate!
