How is chip tuning done. How and where is it better to do chip tuning

Drivers approach the choice of a car quite responsibly and with great trepidation. However, over time it may not be enough. On the other hand, buying a new and more powerful machine is an extremely expensive decision. The ideal way out of this unpleasant situation is engine chip tuning, which has gained really wild popularity in recent years. In this article, we will talk about how to do chip tuning with your own hands and what a novice master needs to know and be able to do in order to avoid annoying mistakes and ruin the software stuffing of expensive nodes.

The ideal alternative

Not so long ago, chip tuning seemed impossible. Why? The fact is that modern internal combustion engines are necessarily equipped with an ECU, or simply electronic control units. The electronic filling made it possible to programmatically regulate the characteristics of both the internal combustion engine itself and each of its individual nodes.

The internal combustion engines of old-style cars do not have such electronics, so all settings are made exclusively mechanically. What is the progenitor of chip tuning, and what methods were popular before the advent of electronics in the design of modern engines? Such operations for modifying engines include the use of turbocharging, pistons and connecting rods made of lightweight materials, and other types of interference with the standard design.

It is almost impossible to do such an operation on your own without certain skills and equipment. In addition, do not forget about elementary risks: any repair carried out illiterately can have a deplorable effect on the condition of both the engine and the car as a whole.

For this reason, chip tuning is much easier. In addition, in this case, you do not have to interfere with the design of the internal combustion engine, change the parameters of its components and disassemble the complex and sensitive mechanism.

ICE chip tuning is not always done on its own, however, in any case, this operation is simpler and faster than the usual methods of upgrading ICE. What is it?

The fact is that the electronic one is endowed with a program, which is a translated binary code and, using a computer, is recorded on the built-in storage medium. This program, in fact, controls and changes the operating modes of the internal combustion engine, allowing it to reveal its potential to one degree or another.

The modern automotive industry is trying to make the car a transport not so much powerful and comfortable as environmentally friendly and safe for the environment. For this reason, many engine models do not try to make them as powerful as possible, artificially cutting down their characteristics for the sake of lower fuel consumption and emissions of combustion products into the environment.

To return the motor to its potential, the firmware developers have changed the standard programs of the control units in such a way that the internal combustion engine gives out its maximum parameters. At the same time, the amount of emissions increases, but, despite this, fuel consumption becomes less, and the driving comfort and acceleration dynamics are incomparable with those before the flashing procedure.

How it's done?

To do chip tuning with your own hands, in addition to the car itself, you need to have two important components, without which this operation, in fact, cannot be performed. The first component is a special adapter. Its task is to interact with a laptop or personal computer with a machine by connecting to its diagnostic connector. Usually, such a connector should be looked for under the steering column, but it would not be superfluous to clarify this point in the documentation attached to the car.

The second component is the software and firmware program, which will eventually be implemented in the electronic engine control unit. The software that needs to be installed on the computer is usually included on a CD with the adapter itself. If there is no such disk, usually the instruction manual indicates the site from which you can download the desired distribution.

With the second part, everything is somewhat more complicated. Several programs usually come on the same CD as the installation file for the computer program. But the problem is that for each individual engine model, its own program is used, which may not be in the public domain. Usually in these cases, the program is purchased on specialized sites, and then transferred to a computer and firmware is produced.

How is the procedure itself? The first step is to find the diagnostic connector and connect the adapter to it. Then a laptop with a running program is connected to the adapter and they wait until the software “finds” the machine and connects to its block for recording.

The attached program allows you to read files of a certain format only. For this reason, don't be surprised if a malformed file won't load or causes a memory error, indicating that flashing is not possible.

If there are no problems with the format, then the next step will be the actual process of starting the firmware, which can last from 5 to 10 minutes, depending on the ICE model, adapter and software version. At this time, it is strictly forbidden to turn off and start the engine. It is also worth monitoring the state of charge of the battery of the laptop itself, because if the process is suddenly interrupted, the ECU can easily turn into a “brick”.

At the end of the process, the program will display a message about the successful completion of the operation. If all is well, then the internal combustion engine will start without problems and will not make extraneous noise. Usually the difference is felt during acceleration: the car starts to go faster, and its dynamics becomes an order of magnitude better than the old one.

Worth it or not?

Of course, doing chip tuning for free will not work in any case. If you produce it on your own, then an adapter will cost a pretty penny, which is not always easy to find on free sale. If you turn to a third-party company, it will cost less. So, usually the cost of firmware varies up to 5 to 30 thousand rubles, depending on the make and model of the car.

If a motor that is not endowed with a turbine is being flashed, the effect will not be so noticeable. So, on average, the increase in power and torque is 10-15 percent, and fuel consumption is reduced by no more than one liter per hundred kilometers. True, the price of such firmware will be minimal.

Owners of turbocharged internal combustion engines will feel the difference in almost all cases. On average, the increase in performance is from 30 to 40 percent: twice as much as any atmospheric ICE. In addition, the reduction in fuel consumption is also more noticeable: in various cases, the difference can be up to 30 percent in all driving modes.

Summary

Summing up, we can confidently say one thing: chip tuning is the most modern and safest way to increase the potential of the car and its performance. Despite the fact that such a procedure is not cheap, it allows you not to interfere with the mechanics of the internal combustion engine and increase its capabilities. The main thing is not to save money and purchase official equipment and software: in this case, there are usually no problems with the firmware.

Recently, electronic control of transport has become widespread. At the same time, the concept of chip tuning appeared. This procedure is of interest to many car owners, because with its help you can completely change the character of any car. Where to make chip tuning can be found in this article.

What is chip tuning? Where is it made? These and other questions cause increased attention of car drivers.

Chip tuning can be defined as a way to change the mode of control over the movement of a car by correcting control programs. The main goal of chip tuning is to completely modernize the engine management system and increase its power. But this is not all that chip tuning is capable of. Where such a procedure is done, you can find out in a car service.

The question arises: why don't car manufacturers immediately release models with high power? They have reasons for this. One option is to reduce carbon dioxide emissions by reducing engine performance. As an example, we can take the Ssang Yong Actyon with an engine power of 175 horsepower, which runs on diesel fuel, and its counterpart is the same car model, only with 149 horsepower. Although the engines of these cars do not have significant differences.

Which engines can be chip tuned?

It is not advisable to carry out this procedure if the car has a naturally aspirated engine. It's simple: for such motors, the power can only be increased up to 7%. In practice, this difference will not be noticeable.

The engine firmware process is complicated by the fact that the engine control unit has a strong connection with other important systems and transmission. This is why engine adjustments can adversely affect transmission performance. No less important is the level of professionalism of the master, on which the changes in the character of the car and the preservation of its original characteristics depend.

If you correct the ECU, then you will immediately need to change the gearbox. This procedure is not easy. Sometimes this is simply not possible, for example, in the case of the BMW 7-series. In this car there are about 80 blocks tightly connected to each other.

The cost of the firmware procedure

Depending on the brand of the car and the professional level of the master, the price of chip tuning varies between 10-25 thousand rubles. You can, of course, save money and adjust the motor for a thousand rubles, only this work will be of a handicraft type. Turning to a reputable company where you can do chip tuning, you will have to pay a couple of thousand dollars, or even more.

The make of the car also matters. If, for example, you flash a Niva, then you can pay 2,000 rubles, for a BMW they will ask for a minimum of 5,000, and chip tuning a sports car will cost several thousand dollars. More information about prices and methods of carrying out can be found on chip-tuning.ru.

Benefits of chipping a motor

Speaking about the advantages of engine firmware, it should be added that all the pros and cons of this procedure apply

to subjective opinion. After all, for someone, a plus may seem like a minus and vice versa.

The main advantages of chip tuning include:

• Noticeable savings in fuel consumption;
• Additional horsepower;
• Improved driving dynamics;
• High responsiveness of the gas pedal;
• Correction of the program and characteristics of the engine.

The positive aspects of chip tuning are not given much attention because of their obviousness and indisputability.

Cons of chip tuning

Arguing about the effect of the firmware on the engine resource, it should be stated that this procedure does not have any positive effect on the engine. However, there is nothing critical in its implementation. Any chiptuner cannot give any guarantee that the engine will operate safely after the adjustment. Therefore, it is better to turn to trusted specialists who will bring the engine to safety limits.

The most important negative side of “chipping” is that after it the engine will no longer be environmentally friendly due to an increase in exhaust emissions into the atmosphere.

It would not be superfluous to mention the factory warranty, which automatically loses its validity from the moment the engine is “chip”. After all, not a single manufacturer will have a desire to pay for the repair of a motor that does not correspond to the initial indicators. Almost all chip tuners insist on convincing car owners that no one will be able to see changes in engine performance.

But surely the manufacturer cannot be so stupid as not to see the difference? With the help of special devices, you can easily determine the presence of interference. Even if you drive the car to the service, you must first return the engine to the factory settings.

Each owner decides for himself whether it is worth doing this, where you can do chip tuning and whether it is really necessary. It is important to understand that the firmware of the motor will significantly increase the potential of the driver. After all, the life of the engine does not depend on the changes made. but on driving style and proper care of the car. The main thing is to learn how to take care of and competently operate your car, regardless of the type of engine, whether it will be reconfigured or factory.

Currently, more and more vehicles are being produced equipped with. So far, not everyone can afford such cars, but in the near future the number of cars without "brains" on our roads will decrease at least twice. Despite the growing popularity of on-board computers, very often their work leaves a lot to be desired. Therefore, as “brainy” cars increase on the roads, the service associated with their maintenance is becoming more and more popular - car computer firmware.

The main goal pursued by the creators of on-board car computers is to provide maximum comfort to the driver and passengers during the trip. In the case when such a device does not cope with its work, it needs the so-called (from English microcircuit adjustment).

Flashing the brains of a car is the most optimal and least expensive way to increase, improve the dynamics of a car and at the same time not remake the engine.

For those who are not yet very good at information, we explain that the electronic brains of a car are an electronic engine control unit, the operation of which is determined by some program. By changing its parameters, you change the behavior of your "iron friend".

The manufacturer's firmware is characterized by the presence of a certain reserve for the ability to increase power, torque, speed and maximum engine speed by changing the software in the "brains" of the car. The fact is that cars, the "brains" of which are strongly clamped into the framework of the norms in terms of the level of toxicity. Chip tuning was invented precisely in order to expand these limits.

Reasons for flashing

The factory firmware of domestic and foreign cars is far from perfect. This is especially true for domestic manufacturers, who can produce a car with a frankly defective one. Criteria for determining marriage are easy to track:

• the car has sluggish dynamics;
• the engine can stop at the most unexpected moment in any mode;
• failures are present;
• uncertain start in the cold season.

Such problems can only be eliminated by changing the engine software. It is worth noting that you do not need to be stingy and it is better to reflash the brains of the car than to buy a new catalyst, oxygen sensor, particulate filter, etc., when they fail due to improper engine operation.

Also note that Euro-3 and Euro-4 systems are designed to use expensive and high quality. Firmware is also required for safe filling of domestic gasoline.

Which programs are better to choose

At present, a market has already formed for adjusting firmware even in the vastness of our country. A program for flashing a car must necessarily meet all the quality standards of such information products, otherwise, instead of getting rid of problems, you will double their number.

The most famous and reliable foreign manufacturers of programs for the on-board car computer are chiptuning.com, chip-tuning.de, upsolute.com. Among domestic software producers, SMS Software, chipsoft.ru, adact.ru, chiptuner.ru and pauluschip.ru have proven themselves well.

Similar ready-made programs can be used if you own a stock engine.

Stock engine firmware

You can reflash the on-board computer at a car service. In the first case, you will have to pay a considerable amount of money, and in the second, you will spend a small amount of time and deal with the manual for this operation.

On the video - the firmware of the Chevrolet Aveo on-board computer:

Brief instruction that the new software on the car:

1. Before starting the flashing, you should write down the version of the hardware implementation of the car computer. You will find it in the top line when power is applied.
2. Now you need to download the update file and bootloader that match the version of your on-board computer. If it doesn't match, it won't work.
3. The next step is to connect the COM port of the adapter to a personal computer and connect it to the on-board computer using a connector. It is also necessary to connect power to a special connector, but do not supply it.
4. Now run the Boot24 program. A window with several sections will pop up on the screen: “Open firmware file”, “Select COM port”, “Download”.
5. First, select a COM port. A small triangle will appear on the screen, clicking on which will open a list of available ports. Now select the port to which the K-line adapter is connected, and click the "OK" button.
6. Next, click the "Open Firmware File" button. In the window that appears on the screen, specify the file with the firmware (*.rom) and click the "OK" button. This file is located in the folder with the program itself.
7. Now you should turn on the power of the on-board computer and click the "Download" button. On the display you will see the inscription "Turn on the BC". To cancel the installation, click Cancel.
8. After turning on the power, the utility will start loading, which will be indicated by the growth of the progress indicator of the installation process. If you messed up somewhere, the download process will not start. Upon successful installation, the message "Download completed" will pop up. After that, your on-board computer is ready to serve faithfully again.

What to expect from flashing

Most motorists are concerned about only one question regarding chip tuning - how will it change qualitatively? Experts advise not to chase power, as the maximum increase in horsepower can adversely affect the comfort in driving a car. Smooth movements of the car can be replaced by jerks and twitches in different driving modes.

On the video - firmware BC Lada Grants:

Choose a program that will add not speed, but comfort in driving and save you from factory defects.

Correct tuning of the brains of the car will lead to the following changes:

• engine operation will become more elastic;
• traction will be more even and smooth;
• the comfort of driving the machine will increase;
• power and torque will increase up to 15%;
• will improve;
• the maximum speed indicator will increase;
• jerks will disappear when shifting gears and the thoughtfulness of the automatic gearbox;
• slightly reduced fuel consumption.

In addition, during flashing, you can turn off lambda probes, catalysts, adsorbers, etc. Flashing the brains of a car helps to increase the resource of the power unit, as engine operation is optimized, factory errors and excessive depletion of the fuel-air mixture in high power modes are eliminated. Euro-3 and Euro-4 systems. Fuel consumption may remain the same. However, during acceleration, it will no longer be necessary to stomp the gas pedal, which will significantly reduce the load on the engine.

If you have spent a considerable amount of money and purchased a smart car, then do not be stingy and reflash its “brains”. The result will not be long in coming and will fully pay off!

Everyone knows the phrase of one famous hero - "A car is not a luxury, but a means of transportation!" For many car owners, the appearance of their "iron friend" is an expression of their own individuality. Someone needs a solid, someone elegant and even aggressive. However, any car exterior loses all meaning if it does not have the main advantage - excellent engine performance, ease of control.

All this can be achieved with the help of tuning (English tuning - tuning) of the engine. These works are in rather high demand.

The mass-produced engine on a car is designed for a decent margin of safety and is designed to preserve the engine's life. And for most car owners, maximum performance is not needed for daily traffic on well-maintained paved roads. You can increase engine power by two main tuning methods - through design improvements and reconfiguring the electronics. Let's take a closer look. These are just two technical methods.

What is chip tuning and what does it give

Chip tuning is the tuning or reconfiguring of the engine electronics.

Chip tuning is performed to improve the following engine characteristics - improve the operation of the cooling fan, stabilize cold start and idle modes. Professional programs, purposefully written, improve about fifty operating parameters of the engine.

This tuning method is designed for most modern engines controlled by an electronic unit, designed for maximum resource savings, minimum fuel consumption and low exhaust toxicity. He, according to the manufacturer, is not configured to receive the maximum. Replacing the engine control program is the task of reconfiguring this unit.

Thus, the solution to this problem is to reprogram this electronic chip containing this program. And this replaced program should take into account a lot of features, and most importantly, the capabilities of this engine model.

Such tuning is a very responsible task. Programs written by amateurs are simply dangerous to use - after all, only a professional can perform the optimal combination of the interaction of technical factors. Therefore, such chip tuning by car manufacturers, as a rule, is carried out for a fee. It is the manufacturer to perform such tuning will be the safest for each specific engine model.

It should be understood that as a result of the chip tuning, to one degree or another, both a decrease in the resource and an increase in fuel consumption will occur, from one liter or more for every 100 km of track. In addition to the fact that the engine will start to work at higher speeds (this is what causes the increase in power), the very ability to press the pedal provokes a high-speed driving style. It should also be understood that the requirements for the brand of fuel may also increase. However, with the help of chip tuning, you can also moderate your appetite, but as a rule, the most economical settings are set at the factory.

On turbocharged engines, chip tuning has the greatest effect, since the program will be able to control the timing of the turbo boost more optimally, as well as the maximum pressure value. This factor gives an increase in power up to 30%, and torque - up to 40%.

How to make chip tuning with your own hands

First of all, we must warn that doing chip tuning with your own hands is a very risky undertaking, but if you are confident in your abilities and that you can figure it out, then why not try it. In extreme cases, it will be possible to give the car to the service so that everything is restored there.

In addition, it should also be said that it is expedient to do chip tuning with your own hands only if you have the necessary equipment and software available or if you know where you can borrow it all. You can download the software for free, but in this case, you yourself understand that no one will give guarantees that everything will work.

Buying everything you need for chip tuning is unprofitable, since it will be more expensive than doing this procedure in a car service. Therefore, before deciding to do chip tuning yourself, you should still think carefully, but do you need it?

Procedure

If you still decide what you need, and the spirit of Kulibin has taken over you, then here's what to do ...

1. Study up and down specialized forums dedicated to chip tuning with your own hands, for example, this one: auto-bk.ru/forum/. Be sure to find the section dedicated specifically to your car model.

2. Decide what kind of software and what equipment you will need.

3. Install the software on the laptop, make sure it works correctly

4. To connect the laptop to the diagnostic port of the car, a special device is used - a K-Line adapter or another, depending on the car. This device, as a rule, also requires installation on a laptop. Make sure you get the right device for your car

5. After installing all the necessary programs and drivers, you can proceed directly to chip tuning. It is better to do this procedure in the garage so that you can connect the laptop to a power outlet.

6. Make sure that the laptop is securely standing and will not move anywhere. Check the reliability of all connections (to the diagnostic port of the car and to the laptop) so that not a single wire jumps out during the calibration program.

7. Turn on the ignition

8. After that, you can run the engine calibration program in accordance with the instructions for it. After that, it remains only to wait for the end of the program. This may take 20 minutes.

9. When the program finishes its work, turn off the ignition and leave the car alone for 5 minutes. At this time, you can turn off the equipment.

10. After 5 minutes, you can start the engine and enjoy the result. You made a chip tuning with your own hands!

If during the procedure some kind of failure occurs, then you need to turn off the ignition, wait 5 minutes. Then turn on the ignition and repeat the procedure again. But it is better to do everything possible so that there are no failures. To do this, use only proven software.

In addition, you need to know that chip tuning can be done by replacing standard elements with ready-made tuning ones, or by adding some special devices. But this is purely individual for each individual car, and you can easily find this information on chip tuning forums.

Chip tuning video

In this video, the price of chip tuning is called one million rubles, but we are talking about Belarusian rubles, which is approximately 3,500 Russian rubles.

In conclusion, it remains only to say that chip tuning is most effective on engines that, in terms of their characteristics, allow at least something to be changed. If we take, for example, the engine of the VAZ nine, which produces 81 hp, then it is hardly possible to achieve any tangible results. To see this, watch this video:

The principle of operation of a diesel engine and a gasoline power unit are different from each other. However, there are general points that are directly related to do-it-yourself chip tuning:

1. Fuel injection parameters, limiting CO emissions into the atmosphere, the main parameters in different engine modes are controlled by an electronic control unit.
2. Each electronic control unit (ECU), regardless of its type, has pre-installed software versions that specify specific parameters in all engine operating modes. During operation, the electronic control unit compares the current parameters, receiving the corresponding signals from the sensors, and changes the operation of individual equipment to obtain factory parameters.

Help: ECU (electronic control unit), ROM (read only memory), software (software)

The question arises - how to increase engine power with your own hands by adjusting the parameters of the control unit software and is this a real task? To do this, let's take a closer look at the basics of chip tuning.

What are the methods to increase power

Chip tuning is the modification of the software parameters of the electronic control unit in order to increase the power and improve the dynamics of the car without making changes to the engine design. Serial firmware has restrictions on power, torque, maximum speed of the power unit. Using this reserve to improve the performance of a car is called flashing or chip tuning.

In addition to chip tuning using special software and removing the control unit (or re-chip through the diagnostic connector), there are other innovations in the automotive industry to reduce fuel consumption using additional equipment. But such equipment (for example, Tuningbox) may not give tangible results - such devices in fact "deceive" the car's sensors, which allows you to influence individual parameters.

The same devices include a block for increasing the power of a diesel engine, which operates in parallel with the control unit, and, according to manufacturers, is capable of increasing the power of the power unit up to 30%. At the same time, the probability of failure of the injection pump (for diesel) increases many times, the resource of engine parts is reduced, so it is better to use firmware and chip tuning of the car to increase the power of the power unit, reduce fuel consumption.

Features of the ECU and factory firmware

Software developers for injection system controllers take into account efficiency, engine life, exhaust toxicity, fuel consumption level, and based on this information, they offer standard (factory) software settings. The program is stored directly in the read-only memory (ROM) of the control unit - this is data processing software, tables with coefficients for all engine operating modes.

But what is engine firmware and how is it related to changes in data in the software of the electronic control unit and chip tuning of the car? The ECU receives data from various sensors and provides control of actuators taking into account factory coefficients. If you change this data through chip tuning, then you can affect the operation of any devices that are controlled by the unit.

Self-chip tuning of a car engine

Self-re-chipovka of the engine is easy and fast if the ECU has a Flash ROM installed. If the block uses a ROM type EEPROM with UV erasure, then you will need to use a programmer or a ready-made microcircuit. By self-flashing and chip tuning of a car, they basically mean the first method - we will consider it.

Required:

• K-Line adapter for connecting a laptop to a connector on the block (ready-made or made by yourself).
• Firmware for chiptuning your car engine.
• Software for loading firmware (for example, ChipLoader, Delco Suite or similar software).

The procedure for flashing an engine using a computer is as follows:

1. Determine the type of ROM used and the version of the factory firmware. As a rule, all the necessary information can be found on the cover of the control unit.
2. Find firmware for your car. What are the ways to increase engine power using firmware? You can download the finished version on the Internet, buy commercial firmware on specialized sites, use the firmware editor to independently change the parameters that affect engine power (unless, of course, in your particular case it makes sense to increase power).
3. Upload the tuned firmware from a computer through a loader (software for download) or a programmer for do-it-yourself chip tuning of a car engine

The programmer is a special equipment for chip tuning foreign cars, which is connected via a laptop or directly to a Bosch, Delphi, Siemens, etc.

Consider how to make chip tuning yourself using a loader. If you want to experiment with various parameters - operating modes, idling, starting, warming up, injection time, etc., then you should download and install special software - ChipTuningPRO. This is commercial software for editing and creating firmware. You can also use free programs for car chip tuning. In the program, you can calibrate various parameters and save as a file ready for loading into Flash memory, but you will have to do this at your own peril and risk. ChipTuningPRO software or similar editors will allow you to perform chip tuning yourself and get a noticeable result in the engine.

If you have chosen a quick way to tune the engine using ready-made firmware (free, commercial), then you will need to do the following:

1. Connect the adapter to a Windows laptop. The computer will assign a virtual COM port to the cable. You can find out which port was assigned directly in the control panel. Here you can also set the port speed, which is required to download the firmware using the free ChipLoader program. Drivers do not need to be installed.

1. Remove the ECU, connect the unit to the adapter according to the diagram. For each unit, depending on the manufacturer and model, you will need to independently find the connection diagram.

1. Run the ChipLoader chip tuning program or a similar free downloader. In the program, configure the COM port that was assigned by the laptop and its speed for transferring data from the computer to Flash.

1. Connect cable to laptop. Click on the "Establish connection" button. It is not always possible to do this the first time.

1. As soon as the connection with the unit is established, set the path in the program to the finished firmware and click on the "Download Flash" button.

1. Disconnect cable. Install the block in the car.

1. Turn on the ignition, wait up to 5 seconds, turn off the ignition.
2. That's it - chip tuning is done. You can start the motor and check the result of the flashing.

All information lost when the power is turned off will automatically recover after a while. No other actions after installing the electronic control unit do not need to be performed.

Advantages and disadvantages of DIY chip tuning

A person who is not familiar with the basics of modern internal combustion engines can be scared and puzzled cons of chip tuning. Let's look at the pros and cons of chip tuning.

The advantages of chip tuning the engine include:

• Noticeable reduction in fuel consumption and increase in engine power.
• Increase the torque of the power unit.

Among the disadvantages of flashing are:

• Reducing the resource of a diesel engine with an aggressive driving style.
• Reducing the resource of the gearbox.
• Possibility of damage to microcircuits due to incorrect connection, attempts to install inappropriate firmware versions, perform operations with errors when changing parameters, and installing the firmware yourself.

Therefore, to the question of whether chip tuning is harmful to a car engine, each car owner must answer for himself. It all depends on the purpose of flashing, driving style, timely error diagnosis.

It should be understood that installing ready-made firmware or editing existing versions are common ways to reduce fuel consumption on cars with gasoline, diesel, LPG. But even in the simplest programs, you will not find parameters that allow you to directly change the maximum speed or remove the speed limit, fuel consumption, etc. In commercial programs, you can change the behavior of the engine in various modes, but changing parameters without a minimum knowledge of what it will give is far from the best option if you do not know the basics of car engine chip tuning. It is better to at least use ready-made firmware - economical, powerful, etc.

Chip tuning of a diesel engine has the pros and cons in fact the same as a gasoline engine. Only among the minuses of chip tuning can be noted the negative impact of changing parameters on the injection pump fuel pump.

Efficiency of chip tuning: is it worth it?

Please note that:

1. No one will say how chip tuning affects the engine resource with self-flashing. The official factory firmware is a software product tested and repeatedly tested by the manufacturer, which uses the parameters recommended for a particular engine.
2. Flashing and changing even individual parameters can significantly affect the automatic transmission. For example, a significant increase in maximum torque can quickly disable the automatic gearbox.
3. The manufacturer knows how to increase engine power without negative consequences - numerous studies are being carried out, the plant bears a guarantee for increasing power by changing the parameters of the motor.

If all this does not stop you, then you can safely proceed to chip tuning with your own hands. The main thing is to study the forums about your car in advance, download the necessary software and firmware, buy an adapter to connect a laptop to your computer. You can always download the factory firmware again (roll back), if not on your own, then by contacting a car service.
