How to make an engine chip tuning and give a new life to the car. Chip tuning equipment - flashing secrets Difficulties associated with chip tuning

Do-it-yourself chip tuning is a phenomenon already quite common in our realities. Russian men - they are like this: just let me save on a trip to the service station, if you can solve the problem with a friend in the garage. Although, of course, do-it-yourself chip tuning of an engine is not the easiest procedure, and if something goes wrong, there is a risk of significantly pulling your nerves and your wallet.

DIY chip tuning for beginners - the basics

Where did the concept of engine chip tuning come from? From those times when the trees were still big, the girls are prettier, and the first electronic control units (ECUs) for the engine have already appeared in cars. It was then that some especially smart car owners came to understand that if there are microcircuits with a processor and a controller that set certain parameters for the operation of the engine, then it is possible to replace them ?!

The first do-it-yourself chip tuning - it really was do-it-yourself chip tuning and, in addition, a soldering iron with rosin and solders. In words, the manual is very simple: I removed one microcircuit from the board and soldered another - with the parameters "sewn" there in advance. And voila! - The car drives differently.

Often better, sometimes worse than before. Then I had to repeat the process. Now everything has changed: do-it-yourself chip tuning has become much easier - a laptop with special software, a diagnostic connector, a programmer - and go! In fact, the current do-it-yourself chip tuning is the same flashing as with modern smartphones. Responsibility, perhaps, more.

How to make a chip tuning of the engine with your own hands - and what it will give

It is no secret that many owners - especially those who already have some experience in driving their car, would like to slightly improve some of its characteristics. Most often, the requirements are as follows: either improve the dynamics of the car, or reduce fuel consumption. Do-it-yourself chip tuning is the easiest way to do this, and perhaps the most affordable for the average driver.

Do-it-yourself chip tuning - intervention in the control electronics of the engine in order to change any characteristics - can be of varying degrees of depth: either a complete flashing or replacement of the control electronics, or a milder option: intervention in the database of the car's on-board computer.

There are special tuning kits: for example, the German RaceChip or the Belgian Remus Powerizer promises a power increase of up to 30%, coupled with a 10% fuel economy, while maintaining a normal driving style.

In fact, such chip-tuning boxes, visually representing an ordinary plastic box with a "printer" connector, can be installed on any type of engine - both gasoline (atmospheric or turbocharged, not so important) and diesel. Its feature is a shallow intervention in the operation of the engine control unit, and not a classic flashing.

Do-it-yourself engine chip tuning - pros and cons

The main disadvantage: with a complete flashing of the control unit, there is a risk that something will go wrong somewhere - as when reinstalling Windows, for example. But if on a regular computer it is easy to roll back the system or re-roll it, then with a car everything is a little more complicated.

In the most sad cases, you can even say goodbye to the old electronic control unit. And the chip-tuning-box technology implies, rather, the addition of the information base of the on-board computer that controls the engine with various data necessary for the operation of the motor in various modes, initially “hardwired” in this block.

Another plus of such chip tuning boxes is that they are not detected by diagnosticians at service stations of official dealers from whom the car was purchased. And, of course, this does not entail withdrawal from warranty service - which is also important, especially for owners of two-three-year-old cars with low mileage. By the way, one more important point: after installing the chip, you need to drive 150-200 kilometers in order for it to be calibrated and coordinated with the ECU.

Usually, after installing a chip tuning box, the car becomes more responsive to the gas pedal, accelerates somewhat more dynamically (here it is also important to take into account the initial engine parameters - for example, no VAZ chip tuning with your own hands will give, for example, the "top ten" the dynamics of Mitsubishi Lancer or Subaru Impreza) and brings more positive emotions to the car owner.

DIY chip tuning - how it works

The engine has a computer that “tells” when the spark in the candles will ignite, how much gasoline should be poured into the cylinder by the injector, when the turbine should start blowing and with what effort - all this is controlled by one small box, which can sometimes be in very unexpected places. Do-it-yourself chip tuning allows you to change the program that is stored there, and in which all the factory values ​​\u200b\u200bof certain parameters of the car engine are entered.

It's simple: a diagnostic connector, connecting to a computer, "creaming" the old firmware and "knurling" the new one. The essence of the current chip tuning: to come to the service station to the guys with a laptop, in a car with 120 hp. and for a conditional 5,000 rubles, remove already 150 hp from your engine. - and it's not magic.

The engine has various fuel maps that are regulated by several parameters - they, with a certain skill, are downloaded and changed: many engines today have an extensive resource for increasing power - they are even “extinguished” for the sake of the environment.

The ignition is not set optimally - if you change the angles, make the spark ignite earlier and give more fuel from the nozzle - you can easily “add” 10-15% of power from an atmospheric engine. If the engine is turbocharged, the turbine valve operation algorithm is changed.

As a result, it starts to blow earlier and stronger, plus everything is the same with ignition and nozzles - this can give up to 30% power increase. And most importantly, without loss of resource characteristics! The most fertile ground for chip tuning is turbodiesel engines: the work will give an increase in power, plus fuel consumption will remain the same.

Most often and most effectively, chip tuning looks on those motors that are delivered to Russia and Ukraine with a much lower degree of forcing - the tuners simply fill in the "European" or "American" firmware - it works 100% efficiently and safely. It is also worth "chip" to transfer the maximum torque to lower engine speeds.

They are the most working - and remove "micro-dips" during overclocking. This is a plus! After all, the main thing is not only an increase in power, but also an increased elasticity of the engine. Although if the motor is initially not very good, it cannot be radically corrected by any "chip".

DIY chip tuning and its dangers

It is more difficult if the characteristics of the motor begin to change to please their whims - then the engine starts to work in several modes unusual for itself. Which often affects its motor resource. Another problem: those who do chip tuning in Uncle Vasya's garage can sometimes be dishonest. For example, instead of flashing, such comrades can simply change the response to the gas pedal - by installing the so-called "jetter".

The fact is that the electronic engine unit “feels” when and how you press the gas pedal - you press a third, it will pour fuel by a third. Pressed more thoroughly - the nozzles will open to the full. With the “jetter”, every time you press the pedal, the car tries to tear from its place, like Usain Bolt. That's all the change. At the same time, fuel consumption, of course, will certainly not decrease.

In general, if you decide to do chip tuning with your own hands - find all the information about your engine, its power characteristics. The Internet is big, everything is there. How to check the efficiency of work? Only measurements on the stand. In the stock version and "chip". Look at the charts and compare.

Remember that as a result of unsuccessful chip tuning, irreversible changes in the operation of the motor may occur, which can lead to very expensive repairs. By the way, if you “chip” a gasoline turbocharged engine, you will have to switch from the 92nd or 95th gasoline to the 98th. And, of course, there may be a problem with the gearbox: will it tear it due to an increase in power and increased torque - in any case, it begins to slowly wear out the gearbox.

And the funniest thing: if you bought a used car that was already "chipable", and the previous owner did not say anything about it, then you can upload exactly the same custom firmware as it was. It's funny, but true - you can pay money (usually - from 150 to 400 USD, depending on the degree of complexity and depth of work, but chip tuning boxes can cost even more) - literally for nothing.

Take it, tell your friends!

Sometimes car drivers need to improve the engine, that is, increase the power characteristics, which is done by chip tuning. This can only be done for cars where there is a motor ECU, which can be reprogrammed and can affect the performance of the motor. To increase the power parameters of the motor, a special module is required, or. This is a small microcircuit that provides reprogramming and optimization of the engine, increasing certain characteristics in a big way. Often, the ECU is “reflashed” in highly qualified service stations, which reduces the risk of negative consequences. But sometimes the question arises, how to do chip tuning yourself and is it possible a priori?

• The speed of the car is increased, allowing overtaking on highways with heavy traffic, without risk.
• An increase in traction and speed characteristics, which makes traveling on city roads more comfortable.
• Tuning a car engine with a chip is the easiest way that does not interfere with the integrity of the engine.
• Easy start when the car is loaded and the exclusion of engine shutdown in the hot season when the air conditioner is on.
• Saving combustible mixtures - fuel when traveling.

Depending on the brand and model of car, the increase in the above indicators may vary significantly. You can see how the power characteristics change before and after the installation of chip tuning, using the example

We make chip tuning of the car motor

If you have already decided to do-it-yourself chip tuning and we are sure that everything will work out for you, it is worth considering every nuance, since reprogramming the “heart” of the machine is a serious process, therefore it is necessary:

• Decide what goals you are pursuing.
• Thoroughly study the whole theory and clearly know what to do.
• Buy a microcircuit in advance, that is, modules, or make it yourself (which you should not do, without professional skills).
• A working and tested computer that will need to be used when "flashing" the ECU.
• Download the necessary software that you will use on your computer.
• Look for a proven program that will provide a clear and correct reprogramming of the vehicle's electronic control unit.

Instruction: chip tuning by yourself

1. The need to reprogram the computer most often arises if an error was made in the factory program, or if it appeared during the operation of the car. Also, an important reason to produce do-it-yourself engine chip tuning is the desire to improve, modernize and improve the parameters of the engine, to make the car more powerful, sharper and more dynamic. A flashing is also necessary to reduce fuel waste when traveling.
2. It is necessary to prepare for the complex process of reprogramming gradually in order to correctly produce DIY chip tuning. You should initially allocate a large amount of time to study the subject, to study the technical features of the engine, that is, to the control system. Initially, pay attention to the stages of working with electronics, as well as electronic systems, and learn (if there is no such knowledge) to work with programs on a computer, with the rules for installing drivers, etc. If you have knowledgeable people to help produce chip tuning online do it yourself you can turn to them for help if you are not confident in your own abilities.
3. Familiarize yourself with the markings and types of ECUs, specify which one your car is equipped with, because the variations of the program that will provide the firmware in the right direction will depend on this.
4. It would not be superfluous to clarify with the master the question regarding the functioning of the immobilizer, that is, the electronic anti-theft device, namely how to turn it off in order to perform a simple reprogramming.
5. Assembling the adapter is easy enough if you have skillful hands. The simplest module (adapter) that is required for a COM port works on bases such as K1533LN1, KT3102, and MAX232. But, it is worth noting that sometimes it also happens that special programs for flashing the system may not work, although the operation of the COM port is ideal. This problem is solved by reinstalling drivers or a new operating system, although these manipulations are not always successful. To solve such a problem, you can try to flash from another computer, which is often the best option. In this case, the most common, already used data cable from a mobile device, created on a PL 2303 chip and one L9637D MC, may be suitable.
6. The proposed scheme (for the ECU January 7.2), which is fully working, shows what the USB-K-Line adapter should be. For a non-standard ECU speed, it is worth supplementing the driver registry with one line with the necessary indicators. If you add a few more transistors and additional parts, you can get another L-line.

1. Two blocks from an IDE computer cable, without additional alterations, can be used as a connector. This train will only need to be cut into two parts so that pieces from 10 to 15 centimeters are obtained. They fit well into the bottom and top slots on the January 7.2 series ECU, but be careful not to confuse their correct location, otherwise you may just burn the block later. Three microtoggle switches are also used - + common 12V, + ignition and mandatory transfer to programming mode +. IMPORTANT! Before performing any manipulations, it is necessary to turn off the second and third toggle switches.

2. To perform the firmware, the following programs are required:

   • Chiploder 1.6 or 1.96 for complex ECUs. Provides high quality flashing.
   • Combiloder 2.18 (comes with Сtp321-full - it starts when the module is connected and is a free loader). The program is needed in order to remove protection from the firmware and, when reprogramming, protect the quality of the software installed in the ECU.
   • ChipExplorer 1.6. Provides viewing of the firmware you found, as well as comparing or editing them.

Carrying out the process of optimizing the car engine

To carry out the correct do-it-yourself chip tuning Nexia or other cars, you need to take into account the fact that the program works fine only on the Windows XP operating system. The same applies if the production do-it-yourself vaz chip tuning, or other car brands. The difference in programming is only in the Flasher firmware, or rather in the file size. If, after starting the program, the calibration file displays the wrong size, then you will need to "adjust this parameter" using the "SMS Enigma new v 1.10 unpacker". It is worth noting that anti-virus computer systems do not like this program very much, but do not worry, there are no virus programs in it. After downloading the program, you need to run it and specify the file that you need.

If you did everything correctly, but your computer has a different operating system, and to produce, for example, do-it-yourself chip tuning prior, with the correct size already selected, which is necessary for this car, you need to install the virtual XP system:

• Download and install the Virtual PC program
• Download ISO image of Windows XP operating system.
• Install and configure the system.

After the virtual system has been installed:

1. A BIOS window appears, where you will need to select CD-Capture ISO Image, indicating the location where you have the ISO image of the downloaded operating system and load the axis by clicking Action-Install or Update Virtual Machine Addons.

2. After that, your K-Line adapter is connected to the computer and a package of necessary drivers is installed:

   • Go to Device Manager;
   • Select the characteristics of the port;
   • We start the XP system;
   • We allow access to chip tuning and adapter;
   • A disk will appear in the "My Computer" window, from where you need to transfer files to a convenient location;
   • We install the driver package on the adapter and check the performance of Flasher
3. We proceed to the beginning of the system boot into the ECU

Produce on cars chip tuning do it yourself accent, VAZ, Priora, Hyundai, Nexia, and other well-known cars, it’s very simple, you need to sequentially perform the following processes:

Preparing for reprogramming

1. Ensure the availability of 220V electricity to power a computer or laptop.
2. After turning off the ignition of the car, we connect the adapter to the USB connector of the laptop, after which we launch the already created XP operating system.
3. Turn on the ignition

Software download

1. Launch Flasher.
2. Specify the calibration file. The download can take quite a long time, so you will have to wait for 20-30 minutes.
3. As soon as the download is over, turn off the ignition and wait 5 minutes. You can also turn off the adapter and computer.
4. Reprogramming completed.

If suddenly, the download process went wrong, and an error occurred, then these manipulations can be carried out again.

We enjoy the impressions of the updated car

Immediately, after reprogramming, the results should be noticeable - the dynamics have improved, the car does not “stall”, the sound of the engine has become more frisky. In an overloaded state, the car does not stop, does not reduce its agility and speed, and the operation of the air conditioner does not affect the operation of the engine so much.

1. A laptop.
2. Programmer.
3. Adapters.

Equipment can be purchased. But if you do chip tuning with your own hands because of the economy, then it is doubtful. An option is to ask friends or acquaintances. But even with all the components, there may not be enough experience that professional chip tuners have been gaining over the years. The risk of incorrect firmware increases. There are many cases in practice.

• You can learn new things;

Many people want to do chip tuning of the engine with their own hands. Car owners consider independent ECU firmware to be a simple matter. “The master did it in half an hour, so I can do it myself.” The desire to save money and do it yourself is typical for the owners of those cars that are not opened during firmware. In difficult cases, the number of enthusiasts is sharply reduced. For example, among the owners of Suzuki Vitara.

What you need for self-chip tuning

1. Official and professional firmware. No one will guarantee the relevance and performance of versions on torrents. ADACT firmware can only be downloaded through the official store. Distribution via the Internet is impossible; a special SenseLock key is used for protection.
2. A laptop.
3. Special software.
4. Programmer.
5. Adapters.

Equipment can be purchased. But if you do chip tuning with your own hands because of the economy, then it is doubtful. Option - ask friends or acquaintances. But even with all the components, there may not be enough experience that professional chip tuners have been gaining over the years. The risk of incorrect firmware increases. There are many cases in practice.

There are those who are so well versed that they can flash the machine on their own without any problems. But such car owners are few.

Do-it-yourself chip tuning advantages

• Slightly cheaper if there is equipment;
• You can learn new things;
• If you like it, you can become a professional chip tuner.

Do-it-yourself chip tuning cons

• The risk of choosing the wrong firmware if you take it from the public domain;
• Time spent to understand the process;
• The risk of errors, for the correction of which you will have to contact a professional.
• Savings in the case of purchasing equipment are negligible or non-existent.

Whether to do chip tuning yourself is up to you. We do not recommend doing this if you are not 100% sure of your knowledge and skills. Lack of experience will lead to sad consequences. Contact ADACT professionals. We have favorable prices. Savings are not worth the potential risks and time spent. See for yourself. Look at the average chip tuning prices for your model.

Many car owners are eyeing the opportunity to make a chip tuning of the engine. But still, compared to the total mass of car owners, this is a drop in the ocean, because most drivers still do not know what an engine chip tuning is, what is its essence and what it is for. We will talk about this further.

Joy has no limit

The first few months after buying a new car, the new owner does not know himself with happiness. He enjoys the beauty and brilliance of the new body, the smell of the cabin, the calm rumbling of the engine.

At the same time, the driver pays special attention to the break-in period, while the motor does not yet give out its maximum parameters and only “grinds” with the rest of the mechanisms.

But time may pass and after 5-10 thousand kilometers nothing changes - the engine does not show the expected dynamics, fuel consumption remains at a high level, maximum speed is limited by firmware, acceleration from zero to hundreds remains the same "stupid".

What to do in such a situation?

If the car has already managed to fall in love and there is no desire to waste your time on, then you can do a chip tuning of the engine. This will resolve the issue at a minimal cost.

Why not

Recently, such a fashionable procedure has become very popular among motorists.

There are more and more craftsmen who are ready to fix the "brains" of almost any car - there would be a desire and money.

It would seem that this service solves many issues - increasing engine power, reducing fuel consumption, removing restrictions on the number of revolutions.

But not everything is so simple. There are many nuances that every motorist should remember.

Before we proceed directly to the discussion of chip tuning, let's recall the history of its appearance.

For the first time, this direction appeared in the early 90s, when computer technologies were just beginning to develop by leaps and bounds.

In just a few years, computers began to perform the most complex tasks in all industries, including the automotive industry.

It was in those years that motorists first learned about the existence of such a useful system as an on-board computer.

The first software began to be created, which made it possible to make adjustments to the operation of the car's electronic system. In fact, it was with this that the era of "chip" began.

The principle of chip tuning is very simple. Using a laptop and a special program, a specialist connects to the car's electronic unit and makes a number of changes to the system settings.

In this case, there is no intervention in the mechanical part of the car (only electronic adjustment). This is the main difference from the full one with an increase in its power.

How is this possible?

The task of controlling the engine is assigned to special controllers, the settings of which can be changed if desired.

As a result of simple manipulations, the specialist is able to:

1. Increase motor power;
2. Reduce gasoline consumption;
3. Correct the operation of the injectors and the turbine.

In general, the range of possibilities is quite wide.

Such software “intervention” is especially important after the installation of gas-balloon equipment, when coordination of engine operation on different fuels is required.

But in most cases, chipping is done to eliminate factory errors, increase power and reduce fuel consumption. At the same time, such flashing is available for all cars (the main condition is the presence of an ECU and the necessary connectors for connection).

We have already mentioned that well-done work on flashing the engine allows you to make significant adjustments to the features of its operation. At the same time, each motorist sets a specific task for the master.

For some, the most important thing is to reduce fuel consumption, for others - to increase engine power, for others - to make the car more dynamic, but at the same time maintain the same consumption (or reduce it).

There are situations when the main task of flashing is to “demolish” the speed cutoff, which is installed on many models at the factory. Therefore, the final result directly depends on the clarity of the task.

In what cases is a flashing needed

Many car enthusiasts decide to chip tune the engine just because it is fashionable. In fact, it’s better not to joke with the “brains” of the car and climb into them only when it is really necessary.

There are several situations where outside intervention is indispensable:

• firstly, after a few months of operation, serious flaws were found in the engine firmware;
• secondly, when transferring to cars for gas;
• thirdly, in the case of transferring the car to gasoline with a lower octane number (again, in order to save money);
• fourthly, after getting rid of the particulate filter in the fuel system;
• fifthly, after removing the catalyst (this is necessary when switching to a lower EURO-2 class, where there are no such significant restrictions as in the case of EURO-3 or EURO-4);
• sixth, to mask and remove gross diagnostic errors that were made at the factory;
• seventh, if necessary, remove speed, idle or speed limits (if any).

In principle, any of these reasons can lead a motorist to think about the need for this type of tuning. If the problems have accumulated in the complex, then you can’t do without flashing at all.

Main stages

The procedure for flashing the main parameters of the engine takes place in several stages.

First step.

A PC is connected to the diagnostic connector and, using a special program, the main system parameters are read. A few seconds and before the eyes of the master the parameters that were set by the masters at the factory.

There are only two reading options:

• on cars before 1997 with flashing, a number of problems arise, because there were no diagnostic connectors (in the form in which we know them today). But a good master is able to literally “pull out” the memory and reprogram (although this is not possible in all models);
• the second option is to use special software with which you can make changes in the background. At the same time, BDM software is the most popular.

The existing parameters are changed to those that interest the motorist. Only true professionals with experience in setting up such complex systems can do such work.

For greater reliability, it is better to contact specialized companies where it is possible to use specialized software and experience working with each specific car firmware.

There are situations when qualified craftsmen, after reading the factory program, discover significant errors that prevented the engine from reaching its full potential.

Sometimes it turns out to simultaneously increase the torque, increase the engine power and achieve a decrease in fuel consumption, which is a key point for many motorists.

Third stage.

At the last, third stage, all changes made to the parameters of the controllers are "poured" back into the computer's memory. The principle of this manipulation is similar to the one that was performed first.

The time to complete the operation is no more than a few minutes. The most important thing in this whole process is that it is always possible to return to the original factory settings.

Questions and answers

Today there are many car enthusiasts who would like to make a chip tuning of the engine of their car, but do not dare. The main reason is a lot of questions, but the almost complete absence of answers to them.

Let's deal with those nuances of "chip" that most worry motorists.

Question 1. Are software developers at manufacturing plants dumber than craftsmen at service stations? After all, they can fix all the “flaws” that irritate the motorist right away (do not set a speed limit, give the engine maximum power, and so on).

In fact, the power parameter for the manufacturer is not as important as it might seem. Today, more than 90% of all cars produced on the assembly line are not capable of delivering maximum power. There are many reasons for this.

For example, the engine can be deliberately “switched off” to reduce carbon dioxide emissions into the atmosphere.

At the same time, the developer can take a tactically competent move and release two different models (at different prices) - one will have, for example, a power of 200 hp, and the other - 220. And this despite the fact that the engines are the same (only different firmware).

But in most cases, the reduction in engine power is due to the need to comply with the current environmental requirements of EURO-4 (otherwise the car may not be released to the market). That is why most cars do not give out their real power.

In turn, for an ordinary specialist in firmware (as well as for a car enthusiast), EURO indicators are not important. Their main task is to make the engine more powerful, which can be achieved within a few hours. So the point is not at all in the intellect of specialists, but in goals and objectives.

Question 2. Does intervention in the "brains" of the engine affect the resource of the latter?

Many motorists are worried that upon completion of tuning, the motor will not be able to depart the period set by the manufacturer.

In fact, there is not a single study that would confirm or refute the fact of resource decline. Yes, and conducting such experiments is too costly.

If you listen to logic, then working at full power, the engine will wear out faster. But the question needs to be asked in a different way - will the motorist notice this?

In modern cars, "millionaires" are installed, so it is unlikely that anyone will notice a decrease in the resource by 50-100 thousand kilometers. The body will corrode and fall apart faster than an ordinary car will travel such a distance.

But when contacting a specialized company (or even more so a private master), it must be remembered that no one will give any guarantees (especially written ones) of a long “life” of the engine. Each motorist decides to make changes at his own peril and risk.

Question 3. What about the factory warranty?

The most offensive thing for many motorists is to lose the factory warranty. But in general, the format of the "guarantee" and the car is too extensible.

No one will notice the fact of intervention in the “brains” of the engine if it is necessary to replace, for example, a windshield under warranty.

If, after the alteration, the engine itself “fell off the coils”, then amateur performance will immediately be detected, and the manufacturer quite justifiably refuses to make the affected car under warranty.

As practice shows, the fact of intervention is found extremely rarely. But in any case, if you value the warranty, then it is better to wait for it to end, and only then, with a clear conscience, experiment on your car.

Question 4. How much power can be increased?

If the main task of a car enthusiast is to increase power, then his question necessarily concerns the real prospects of chip tuning.

In the case of standard atmospheric engines, one should not expect any special miracles. The optimal increase in the parameter is about 12% (in some cases, 15% can be achieved).

Things are much better with turbocharged engines. So you can achieve a significant "tide" of power - by 30, or even 50% (with the special talent of the master).

Question 5

The service station employee has the opportunity to change many parameters - ignition timing, calibration parameters, excess air coefficient, and so on. But the main thing is not even that.

A good master knows that adjusting one parameter can lead to a change in a whole group of other indicators.

Therefore, the work should be carried out with the expectation of the final result, and not for a change in any one coefficient.

The main thing is to find a "golden mean" when the implementation of one task will not lead to a deterioration in the performance of other systems.

Question 6. What is the point in flashing a naturally aspirated engine if the increase in power is minimal?

Many car enthusiasts, after they learn about the potential effect of "chip", refuse to waste money. But here we must not forget that the increase in power and torque are interconnected.

If the master managed to raise the "horses" by 1%, then the torque will increase by 5-7%. Thus, the car becomes much more dynamic and "brighter" in motion.

Question 7. Does the environmental component always suffer with an increase in power?

Most often this is inevitable and the masters immediately admit this to motorists. In most cases, the ignition timing is changed.

If you make this parameter higher, then the power will also increase, but the amount of harmful emissions will increase significantly. Although, few people care about this, except, of course, the environmentalists themselves and traffic police inspectors.

Question 8. Is the job expensive?

There is no single tariff, because everything depends on the chosen car service and the brand (model) of the car. If you find a single master, he can do the job for a thousand rubles.

Turning to a specialized company, the costs will be much higher - up to 10-15 thousand rubles (for cars with a volume of up to 1.6 liters) and up to 30-40 thousand rubles (for cars with a volume of 1.8 and above).

It is also impossible to say unequivocally that the quality of work in a qualified service will be higher - it all depends on the talent, experience and skills of a specialist.

As for the guarantee, neither one nor the other side will give it.

Question 9

After a number of events, the motorist (which is quite natural) wants to see real changes in the dynamics of the car and other parameters. But many are disappointed, because they do not notice any special changes.

The only thing that can be checked is the absence of restrictions on the number of revolutions, an increase in acceleration dynamics and an increase in power (most often this is immediately noticeable).

If more accurate information is needed, then qualified services have specialized stands on which tests are carried out.

Based on the results obtained, it can be concluded that there are real changes in the dynamics of the car.

Question 10

As practice shows, it is possible. But to achieve maximum results, you can install a special corrector - a small electronic unit that connects between the pedal position sensor and the electronic control unit.

In this case, the signal increases in power and is fed directly to the car's ECU.

By installing such a corrector, you can permanently get rid of the annoying “stupidity” of the car when you sharply press the gas pedal.

Question 11. What is the difference between a petrol engine chip tuning and a diesel engine chip tuning?

In fact, there are no key differences. The steps to complete the firmware are the same in both cases. The only thing that changes is the adjustable parameters.

For example, in a gasoline engine, the ignition timing is corrected. In the case of a diesel engine, the injection angle requires a change.

But here the specialist himself decides which parameter to adjust and which one is better left untouched.

Question 12. Is there a difference in the tuning of turbocharged and naturally aspirated engines?

There are some subtleties in setting up turbocharged and naturally aspirated engines.

In the first case, the main task of the wizard is to change the boost pressure data, and in the second, the fuel supply parameters and the ignition angle.

We have already mentioned that with the right settings, you can increase the power of a turbocharged engine by almost 25-50%, and atmospheric 6-15% .

In addition, the volume of injected fuel is adjusted, which makes it possible to reduce the “gluttony” of the vehicle by 10-20% .

Advantages and disadvantages

Based on the foregoing, some preliminary conclusions can be made about the advantages and disadvantages of engine chip tuning.

The advantages of flashing include the ability to increase engine power (and with it torque), make the car more economical, improve dynamic performance, remove restrictions on speed and speed, achieve faster acceleration, and so on.

But there are disadvantages:

• Firstly, to perform such work, you will have to pay a certain amount (if we are talking about a specialized service, then the costs will be very significant);
• Secondly, you will have to sacrifice the general parameters of environmental friendliness;
• Thirdly, there is always a danger of falling for an unscrupulous master, after which the engine quickly fails. And then the costs are much more serious.

conclusions

If you have already decided to chip tune your car, then you should clearly know a few things - why are you doing this, who will do the work, and what do you want to get out of it.

At the same time, you need to be clearly aware of the risks that flashing the engine of your car carries. This is the only way to be successful in such a risky undertaking.
