Chip-tuning with your own hands - you like to ride, love and strain. Reprogramming of "brains" of a car on-board computer how to make chip tuning

the main / About cars

Surely, every car owner, at least once, but dreamed of more powerful car, I dreamed of feeling anything incomparable sensations of strength and speed. And if earlier, the dream could only come true with the purchase of a new car, today the problem is solved with less costs, and not only financial - engine tuning chip - a unique operation that allows you to significantly increase the power of your car. Let's talk about this in more detail.

History of origin

Chip tuning appeared in the early 90s of the last century, while there was a rapid development of computer technologies. The computer has become universally used in many industries, and the auto industry was no exception. With those for many years now, and the engine chip-tuning, not only did not lose their relevance, but also significantly increased its popularity, becoming a real salvation for many car owners who dream of a powerful and high-speed car.

What is chip tuning

But what is chip tuning? This is a special optimization of the engine of the car, as a result, it increases its power, and, without interference in the mechanical components of the car.

Modern engines are equipped with an ECU - an electronic control unit, which, in fact, and controls the operation of the engine, in accordance with the program embedded in it. It is enough just to modify this software and this will immediately give a tangible result - first of all, the torque, engine power and its "pickup" will improve. In addition, the tuning firmware allows you to upgrade cold launch Auto, fix the ignition advance angle, fuel injection parameters, as well as deactivate some systems that are responsible for monitoring the toxicity of the car exhaust gases.

True, it is worth remembering that holding a chip-tuning with your own hands or by car service, you act on your own risk, losing a guarantee on the car.

Advantages of use

We offer you a list of basic advantages that gives such optimization on your car:

Improved speed acceleration indicators;
Higher speed;
Increase engine power by 5-30 percent, depending on the type of engine used;
Higher car maneuverability;
Improving the dynamics, which reduces the acceleration time up to 100 km / h;
Reduction of fuel consumption - up to 20 percent;
Improving the operability of the onboard complex of the car.

It is worth noting the fact that all this happens without direct interference with the operation of the engine and the settings of the main nodes of the car, and the adjustment is carried out directly at the level electronic systems car.

Are there any deficiencies?

However, like everywhere, there are not only positive moments here, there are disadvantages. Among the main of them are worth it:

Increasing the toxicity of exhaust gases - the lack of rather controversial, since it, as a rule, manifests itself only with an incorrectly carried out;
Reduction of the engine's working resource - for everything you need to pay and for an increase in power including. The more active the engine works, the smallest time he can serve;
Loss of warranty - however, if the operation is carried out official dealerThis problem is solved by itself.

Performing the operation on your own

Conducting this operation at home, is relevant when you want to improve your car, but there is no time, desire or opportunity to wait when the work is carried out in the official service center. Is it worth holding a chip tuning with your own hands? Everyone responds to this question independently, advise it is meaningless and we will not do this, just tell me what is necessary for the engine chipping.

So, in order to perform the operation, we will need:

Firmware - here it is very important to choose a high-quality version.otherwise the consequences will be the most deplorable;
Microcircuit - the choice is quite large and depends on the wishes of the car owner, as well as the brand of its car;
The microcircuit panel is similar to the firmware. Do not chase a cheap copy, it is better to take once, but a quality product.

Conducting the chip operation independently, it is also worth remembering that it can be performed exclusively on a good engine that has been adjusted and calibrated.

Conclusion

Summarizing the above, it is possible to conclude that the competent chip tuning is able to significantly improve the operation parameters of the automotive motor, make it more powerful and economical. Performance of this operation is better to be trusted by professionals not only with experience and knowledge, but also with all the equipment necessary for work.

Chip tuning - Feel the power of your car.

FAQ for beginners:

1.
Question: What is the meaning of tuning?
Answer: Imagine that the engine is a pump on air pumping. Each factory engine has its own volume and its design features. For example, it is 2 engines, it is 8kl. Engine 2111 and 16kl. Engine 2112. If you remove logs from each of these engines and analyze them, we will see that 16kl. Engine 2112 consumes more air than 8kl. 2111, may not be in the entire revolutions range, but at least in high turns of DV.2112 consume more air. Accordingly, the car with dv.2112 will be faster and faster accelerate. Because in dv.2112 more air intake (4 valves per cylinder), instead of 2 y dv.2111. In this way, when we put tuning hardware, camshafts, a receiver, choke, directing release, reset the CHC channels, increase the engine volume or put the turbine, thereby we achieve 2 factors, it is more air intake by the engine and better bandwidth. Than more engine Consumes air the higher its power and moment. For example, factory 16kl. Engine 2112 consumes about 320 kg of air / hour, the turbocharged is about 900 kg of air / hour.
Outcome: more air\u003e More power, less air\u003e less power.

2.
Question: Why after tuning it is necessary to calibrate the firmware?
Answer: Each factory injector car A firmware is recorded in the electronic control unit, which has been calibrated in accordance with the engine configuration. Ie, the firmware has been calibrated in accordance with the volume of the engine, the parameters of sparing shafts, the phase of sparing shafts, the design of the receiver, the design of the throttle assembly, the exhaust system, the capacity of the injectors, etc. The engine controls the firmware, an angle of the ignition advance, composition of the mixture, cold. running and so on. And when we put the tuning camshafts and the receiver, we thus dramatically change the inlet system and the engine gas distribution system. So after tuning, we got new dynamic characteristics Engine, it requires new firmware calibration, under our new engine configuration. Because the factory firmware was configured to the factory configuration, and new tuning Configurations it will not work correctly. There will be jerks and failures in motion, the car will not develop maximum power and maximum speed, cold. The move will not be stable. In addition, the operation of the engine on the non-tuned firmware can cause long detonation, it is the mark of valves, split the pistons, damage to the connecting rods and the walls of the cylinders, in general, at best, the repair of the engine at the worst replacement.
Total: Before tying a car, you need to find an adjustment or to have at least the initial level of knowledge. And of course have equipment for calibrating the firmware. Ideally, any installation of tuning hardware on the engine, such as the direct-flow release requires a new firmware calibration.

3.
Question: What equipment do I need to calibrate the firmware?
Answer: When we picked up the engine with a bunch of non-standard iron, camshafts, receiver, release, etc., we fulfilled only 50% of work. Nichrome all this will not go anywhere without calibrating the firmware. The remaining 50% is the setting of all this minced meat) So, for this you need a system that will allow us to configure all this. Under the word system, I mean the engineering engine control unit and the wiring to the engine sensors. The engineering control unit differs from the usual the fact that the engineering can calibrate the firmware in real time, this mode is called online. Those. You eat behind the wheel, and the adjuster is sitting next to you with a laptop, connecting through the adapter to your ECU and calibrates the firmware to obtain real-time data, such as the composition of the mixture, ignition advance, inlet air temperature, and so on. And accordingly also changes these parameters in real time. Systems for calibration of firmware online mass, it is January, Corvette, Megaskvirt, inventory, and so on. They have one, customize the firmware online. Further, one engineer is not enough, you need another broadband oxygen sensor to see the composition of the mixture in the graduate manifold. There will be little a regular factory oxygen sensor, it only sees the composition of the mixture of 14.7, this means that in order to burn one part of the gasoline, it is necessary to 14.7 parts of the air, and the SDK sees a mixture from 10 to 20, 99% of the engines work in this range of the mixture. For all this equipment, you need firmware and programs that will allow us to configure all this, without programs any equipment a bunch of useless metal and plastic. As a rule, always when buying equipment included programs and firmware, or sold separately. This is the minimum set of adjustment. There is also a mass of devices to facilitate the firmware configuration, in particular the EC sensor that is screwed into the exhaust manifold and allows you to see the temperature of the exhaust gases, it is necessary to adjust the ignition.
Outcome: For calibration online, engineering block with wiring, PX, a set of cables for connecting / flashing a block, software and firmware. Well, the knowledge of all this business)

Question: Where to start tuning, what to do in the first place?
Answer: Before tuning your wheelbarrow need to go to the system that allows you to configure the firmware online. Under the word, the system is due to the electronic control unit. For example, if you have a bosch control unit 7.9.7 on your car from the factory, then before tying your wheelbarrow, it is necessary to replace this unit for January 7.2, if you have a Bosch block 7.9.7 or 7.9.7+, then we simply buy January 7.2 and put it's because The wiring between these 3 blocks is interchangeable. If you have a block, say m74 with e-pedal Gas, then you need to make the same actions, install the ECU January 7.2 or 5.1, but with the replacement of the wiring, because the wiring from M74 does not suit any of the January. Because any of the January does not support E-gas, then, accordingly, it will be necessary to switch to a mechanical choke, and in general E-gas is a solid headache, more hemorrhoids than good. When you go to any of the ECU of January, you can already put tuning hardware. First that you need to do it install graduation system Spider 4-1 or 4-2-1 or insert instead of catalyst, thereby let's breathe the engine better, this will play a huge role in the future tuning. And then when you already have a motor configuration for more seriously, you can easily contact almost any customizer to configure you firmware. At the same time, the ECU is January you can have an ordinary (factory, non-engineering), when the Admitter will configure you firmware on your engineering ECU this firmware will work perfectly on your factory ECU. Properly configured tuning firmware is a key to success. Downloading already ready-made firmware on the Internet spaces for tuning engine configuration, you make a mistake and engage in masturbation, the car may go but not as it should go. There will be a degree, jerk and failures while driving, increased consumption. The firmware is configured individually for each engine, this is another key to success. Free free free cheese is only in a mousetrap. And good and tasty cheese is bought for funds.
Outcome: first go to the ECU January 5.1 / 7.2, then we put the release of the spider, and then the camshafts / receiver / choke and the last four turbines, for each cylinder)

Thank you for the article

Sooner or later, but in the life of many owners of the car with the "computer" the moment occurs when the engine tuning chip turns into a need from which it is impossible to reject.

And whether it is necessary. In this article I would like to note the main nuances and bring some examples, as well as interesting information about this. I will start with the fact that the chip tuning has long been planned to be done, however, as many (if not all), there was a doubt, and his blood did not burn her desire to give. Judge for yourself, specialists (sometimes even acquaintances) this procedure will cost at least 3,000 rubles, and even more.

Considerable amount for a ten-minute procedure. However, rationality won with the arrival of summer, when under the influence of the heat of the car began to "slow down" with air conditioning. It was decided to act myself, it's good that there was a K-Line adapter. Here I am not going to paint what chip tuning with long stories like "small" scientific dissertations. I would only like to celebrate the most important, main nuances.

Why do we all need

The term chip tuning implies optimization (improvement) of the engine programs. Simply put, nothing wrong with this will not be your car. If you need more detailed information, Google is always ready to help you. And now I mean only the main advantages of this process.

The advantages of the tuning chip include:

the possibilities for accelerating during overtaking on the tracks, where there is an intensive movement;
significantly more comfortable driving through the streets of the city due to several increased traction characteristics;
chip tuning is a faster and easy way to tuning a car engine compared to engine boost;
the possibility of easier movement with a fully loaded car
fuel economy.

Helpful information

Preparing for a chip tuning car with your own hands, I reread a lot of information on the Internet, which, mainly, was reduced to the description of the term chip tuning and other "generalized" information. But once he found an interesting survey, which conducted a version of one road site. Three driver were surveyed (this is not a global survey on warming around the world), which recently conducted a chip tuning of their car. In his "interview", they called the main reason for the implementation of this procedure, attention:

small acceleration;
ability;
car power.

According to the results of the survey, two of the three owners spent everything themselves without referring to any salons. What can this be informed of us, ordinary, "unobed" owners? The answer is obvious. Why pay more or even pay, if the entire expensive procedure can be held yourself. There is nothing complicated in it. And indeed, if you think about the numbers that today offer various specialized companies, then we can say that they are somewhat impressive, let's say.

The average cost of chip tuning on atmospheric engine It begins to counted from $ 150, for turbocharged - from 300 dollars. For cars with experience, which "threatens" chip-thing will need to pay from $ 450 for "chipping" atmospheric motor "and from $ 750 - for turbocharged engines.

General instructions for holding chip tuning

Before you begin to perform tuning chip with your own hands, you must consider the following:

why do you need it;
well prepared in the "theory";
have a match at hand (buy or manufacture a second adapter), it is necessary to pretend the verified "computer", and also need to have everything else to replace the software;
iMPORTANT: Find and download software that will be used on your computer;
be sure to find firmware for the ECU ( electronic block control).

Most often, the need for firmware occurs if you need to correct the bugs of the factory software (software), as well as if there is a desire to add the car dynamics and save fuel. This is necessary and when used as fuel on a par with a gasoline of liquefied gas. Some craftsmen conduct chip tuning to explore the device and operation of the engine control system.
Preparations are better gradually. You do not need to try to cover everything at once. It is very important to understand how to work with electronics and electrics, be able to use the laptop at the installation level of drivers and programs. Everything else can help the "smart" friend - search engine, as well as skilled hands and gray substance in the head. It is necessary to get acquainted with the varieties of the ECU and their marking, for which motor is needed what firmware. Try to deal with the issue of immobilizer. When you understand everything (or you will have such a feeling), it should be not sightering to try to discuss with the master on the service virtual theme "How to replace the firmware of the car, as well as to disable (deactivate) immo." To ask the wizard for too long I do not recommend A busy person has a precious time and, most likely, new questions will flow by themselves. But the answers to them are better to try to find himself. It will be very useful.
If your hands are different as skillful not to call, now you can go to the assembly of the adapter. The most common and simple, which is suitable for the Iron Som Port, works on the basis of K1533LN1, MAX232 and KT3102 (the adapter schemes are presented in the photo below). It will cost you not expensive, close one hundred all the equipment. You can take on the radio market. However, there is a small problem here - not all "systemics" are equipped with a standard COM port, and sometimes even those that have it can not work. It often happens that the comport is working fine, the program, for example, will win (satellite OPEN) work, but special firmware programs simply do not go. Changes to settings and the drivers can not give anything like installing new Operations. In such a situation, an option with a stranger computer can be seated, on which, "oddly enough", all suddenly, magical way, starts working. In this case, the already used data cable from the mobile phone based on the PL 2303 chip and plus one MS L9637D will help. This scheme is still one hundred percent (January 7.2), but the registry of the drivers is necessary to supplement one line with the parameters for non-standard velocity of the electronic control unit. As a result, it will turn out a USB-K-LINE adapter. Add two more transistors and several parts, and get a L-line.

You can use two pads from an IDE of a computer loop without rework. This loop is cut into two pieces of 10-15 cm. So they are well included on January 7.2 under the top and bottom of the nest nest (two empty pins pads, as a result, will remain at the bottom or at the top of the block of the block), however, it is important for subsequent connections. Their location, because the block is smelted.

You can also use three microtumbler - general + 12V, as well as ignition + with mandatory translation to programming mode +. Then, before starting any operation, the second and third tumblers should be turned off and turn on three in the order, then two. Sometimes to get a connection, you have to take off the overall +. You can take mandatory nutrition with a car, when performing work on the table - from the "practical" adapter for the current close 500 mA.

To perform flashing. The following programs will be needed: Chiploder 1.6 (more expanded on blocks 1.96) and Combiloder 2.18. The second "prog" comes complete with the CTP321-FULL (this is a free ship, which is started when the adapter is connected). However, it happens that it falls out of work or simply cannot finish the process to the end of the fill.

The first program works well. The second is needed mainly to remove protection from the firmware you found, as well as to install such protection during the fill of the software in the ECU. Without any problems, the protected software from the controller does not exit - there is erasing. It is recommended to prepare for this and have several (found in different places) of factory firmware in stock.

The CTP321-FULL directory after installation has standard and tuning firmware, so that can suit something. You will need a "prog" chipexplot 1.6. With it, you can view the firmware that you will find, as well as edit and compare them. Before starting fulfilling all actions, remember that all responsibility in consequences to fall only on you. If one hundred percent is not confident or afraid to spoil something, think about alternative options.

How to spend chip tuning: practice

Everyone who wants to hold the engine tuning chip with their own hands, but does not know how it will be useful to read this material. For example, a machine is selected Hyundai Accent. AT-5. Good sedanperformed by the skillful hands of South Korean masters. So, proceed to "chipping" with your own hands.

First you need to disassemble the theoretical part of the procedure. For this, the option is perfectly suitable with the study of chipthuning forums. Since there is a Kefico computer in the car, then the firmware can be performed in two ways: with refinement (for this you need to get resistors), and without it, using the ODB-II diagnostic connector. In practice, apply the second method.
Search for verified calibration and good software, which is present in the open access.

On one forum, the Matizovskaya Calibration was found, which has perfectly proven itself in practice. The machine "does not slow down" with air conditioning, moves without failures, there is an economical fuel consumption and more dynamic acceleration.

You can use Kia Flasher to firmware, which will work better in combination with the Orion adapter. You can use Hyundai Flasher. These programs are identical percentage of 99%, the main difference is in the title.

I had downloaded and calibrations, and the program. Next, they launched them on the computer with Windows 7, it turned out - it does not work. What is the problem? It turns out, the program needs only XP. Run the computer again, the program, the calibration file - displays the "file size is incorrect."

I had to return to the forum, it turns out, not everything found out. Hyundai Flasher, according to the results of the study of messages, it works with calibrations that occupy 512kb, downloaded by the same size 218. But there is a solution. You need to download a program called "SMS ENIGMA NEW V 1.10 Unpackinger". All antiviruses react to it, but do not be afraid, this is a reaction to its encryption, there are no viruses in it.

So: I downloaded, I started it, I pressed to unpack, and then chose the file. As a result, the calibration occupied the appropriate 512cb, the Kia Flasher program perfectly sees it.

Preparation of equipment for work.

It is necessary to find a computer with HP OS. This is very important because this nuance will slightly facilitate your work in the future. If still not found, follow in order.

Install virtual xp

To do this, download the Virtual PC program and install it.
Then you have to download the ISO image of Windows XP
Next, the installation and required configuration of virtual XP

(It will be clearer with pictures).

To begin with, you should run Virtual PC

After pressing the finish, the Virtual OS configuration will be completed.

In the virtual "system" window, after it starts, the BIOS window will appear, on its top panel you need to press CD-Capture ISO image, and, at the same time, specify the image from your Windows XP. Then the installation will begin. After installation, load the virtual axis. Click on the top panel of the Action-Install or Update Virtual Machine Addons.

Dale need to install, restart and close the virtual machine. We connect the K-LINE adapter to the computer and immediately install the driver. After that, go to the Device Manager, which is located in the control panel.

Select the properties of the port

Run in your Windows XP virtual machine. Share the software for the tuning chip itself and the folder with the drivers on the K-Line adapter.

In the My Computer folder, a new disk will appear, which will contain files from a shared folder. We throw the folder on the desktop.

Now install the adapter driver, as well as check the performance of Kia Flashera. You must specify the COM-1 port in the settings. Now you can close the virtual XP. After that, you can proceed to load calibrations to the ECU.

Preparation on the venue of the operation

How to choose a place:

The car needs to be put in such a place so that it does not interfere with anyone.
It is important, even necessarily, the presence of electricity 220 volts for a computer.

Let's proceed. Laptop We will put in a flat place, connect the power to it and control so that the computer does not fall, and the power is not turned off, it is also necessary that the adapter does not fall from the connector.

Connect to the diagnostic port of the adapter block, turning off, pre-ignition of the car.

Adapter We connect to the USB port of the laptop, run on it a virtual Windows XP (remind you, it is for those who have on the Windows 7 operating system laptop). Then turn on the ignition. That's so simple. Preparation completed.

Loading calibrations

It is important to remember everything well (you can write) and delete. If you make this step correctly, then everything will work well, you install the connection. Next you need to select "Download" and specify the calibration file. We have to wait for the end of the operation.

Download may take about 20 minutes. When the download is over, you need to turn off the ignition and wait 5 minutes. The adapter at this time can be turned off, the laptop can already be turned off. It is possible that an error occurs during the boot or the circumstances that will interrupt it.

In this situation, it is necessary to turn off the ignition, eliminate the reason that it caused an interruption and start a re-procedure. Five minutes later, turn on the ignition of the car, boot the motor and enjoy. It is possible, as a backup option, take a factory calibration with you, which is called ADE1I52 for most.

Impressions after the procedure

From the first moments you notice that the car behaves differently - the engine sound has changed, the dynamics also changed. In general, we can say that the car began to behave noticeably more.

With the air conditioner turned on, the machine behaves like a tuning chip without it. The machine corresponds environmental Standard Euro-2. In general, after this operation, he was satisfied, considering that all this is completely free.

For the last, I would like to add that I don't call you this article to make a chip tuning immediately, and I am not responsible for future (possible) damage to the machine in the process of tuning chip, performed by yourself. This article is not a call to install these calibrations, you can install any other you find. It's just one of possible optionsI decided to share with you.

Laptop, theoretical knowledge and a great desire to make your car faster and more powerful - this is "three whales" of a successful chip tuning with their own hands. The firmware for the tuning chip can be found on the network.

IN obligatory Before holding a tuning chip, you need to diagnose all systems in the car to exclude other factors (for example, beat air filter, and the standard firmware cannot provide the correct composition of the fuel-air mixture due to the deterioration of air intake).

It is also necessary to know exactly that the control unit supports tuning and various firmware.

We get ready (the issue price is about 200 UAH.) Or make a K-Line adapter. "To" line is a channel, error information and general diagnostic and technical information are transmitted;
We find the necessary firmware for the electronic control unit. Choose the firmware carefully, checking, to match all the marking items, otherwise it will not go;
The next step is to build an adapter. If there is a COM port in lapty, and you go to the most easy option. If the COM port is not, you can make an adapter based on the cable date of the mobile phone, taking as the basis of the PL 2303 and L9637D chip. On the firmware January 7.2, this scheme works, only it is necessary to prescribe an additional parameter string for non-standard ECU speeds.

Two pads from the IDE of the loop will suit the connector. It must be cut into two pieces of 10 cm. You can still use three microtumbler + 12V, and ignition with mandatory translation into programming mode. The second and third tumbler must reboot - turn off and include, observing the oddity of 2.3 - 3.2. Mandatory meals for the adapter can be taken from the car.
For flashing, use the CHIPLOADER 1.6 and COMBILOADER 2.18 programs. It may immediately be possible to consider the program from the controller (it will erase), therefore it is better to have several firmware in stock. Standard calibration that needs to be with yourself just in case, for most cars is called ADE1I52;
For firmware, it is good to use the Kia program - or Hiundai Flasher. These programs only work under XP. If WіNDOWS 7 is installed on the computer, you will need to download the VIRTUAL PC program by which you install the virtual OS;

Principle of operation diesel engine and gasoline power aggregate differ from each other. However, you can select the general moments that are connected directly to the chip tuning with their own hands:

Fuel injection parameters, CO emission limit into the atmosphere, main parameters in different modes The engine is controlled by an electronic control unit.
In each electronic control unit (ECU), regardless of its type, there are preset versions of the software in which specific parameters are specified in all modes of engine operation. When operating the electronic control unit compares the current parameters to give the appropriate signals from the sensors, and changes the operation of individual equipment to obtain factory parameters.

Help: ECU (electronic control unit), ROM (constant storage device), software (Software)

The question arises - how to increase the engine power with your own hands due to the adjustment of the parameters on the control unit and is this task real? To do this, consider more the foundations of the tuning chip.

What are the methods of increasing power

Chip tuning is a change in the parameters of the software of the electronic control unit in order to increase the power and improve the car dynamics without making changes to the engine design. The serial firmware has a limit on power, torque, maximum speed of the power unit. The use of this reserve in order to improve the characteristics of the car is called flashing or chip tuning.

In addition to chip tuning using special software and removal of the control unit (or overpaping through the diagnostic connector) there are other innovations in the automotive industry to reduce fuel consumption using additional equipment. But tangible results such equipment (for example, TuningBox) may not give - such devices on the fact "deceive" the car sensors, which makes it possible to influence individual parameters.

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

Features of the work of the ECU and factory firmware

The software developers for injection controllers take into account the efficiency, motor resource, exhaust toxicity, fuel consumption level, and based on this information are offered standard (factory) software settings. The program is stored directly in a constant storage device (ROM) of the control unit - this is software for data processing, tables with coefficients for all modes of operation of the motor.

But what is the engine firmware and how is it related to data changes in the electronic control unit and chip-tuning car? The computer receives data from various sensors and provides control of actuating devices with the factory coefficients. If you change this data via chip tuning, you can affect the operation of any devices that are carried out by means of a block.

Independent chip-tuning car engine

Independent engine swift is performed easily and quickly if Flash ROM is installed in the ECU. If the unit is used by the EEPROM type ROM with UV erasure, then the use of a programmer or a ready chip. Under independent flashing and chip-tuning car, they are mainly the first way - and consider it.

Required:

K-LINE adapter to connect a laptop to a connector on the block (ready or made independently).
Firmware for chip tuning of your car engine.
Software for downloading firmware (for example, Chiploader, Delco Suite or similar software).

The procedure for flashing the engine using the computer is as follows:

Determine the type of ROM used and the factory firmware version. As a rule, all the necessary information can be found on the control unit cover.
Find the firmware under your car. What ways to increase engine power using firmware exist? You can download the ready version on the Internet, buy commercial firmware on specialized sites, use the firmware editor to independently change the parameters affecting the engine power (if, of course, in your particular case it makes sense to increase precisely power).
Tuuning firmware from a computer Download via loader (software for download) or programmer to perform a car tuning chip-tuning with your own hands

The programmer is special equipment For a tuning chip, foreign cars, which connects through a laptop or directly to the Bosch, Delphi, Siemens block, etc.

Consider how to make chip tuning by the use of a loser. If you want to experiment with different parameters - operating modes, idling, Start, heating, time of injection, etc., you should download and install special software - ChipTuningPro. This is a commercial software designed to edit and create firmware. You can use free programs for chip tuning car. In the program, you can calibrate different parameters and save in the form of a file ready for download to Flash memory, but it will have to do at your own risk. By chiptuningpro or similar editors will allow you to perform a tuning chip on your own and get a noticeable result in the engine operation.

If you have chosen a quick engine tuning using the finished firmware (free, commercial), then you will need to do the following:

Connect an adapter to a laptop with Windows. The computer will assign a virtual COM port cable. Find out which port is assigned, you can directly in the control panel. Here you can set the port speed, which will be required to download the firmware using free program Chiploader. Do not install drivers.

Remove the computer, connect the block to the adapter according to the scheme. For each block, depending on the manufacturer and the model, you will need to independently find a connection scheme.

Run the program for chip tuning chiploader or a similar free downloader. In the program, configure the COM port, which was assigned a laptop, and its speed to transfer data from the computer to Flash.

Connect the cable to the laptop. Click on the "Install Communication" button. It does not always manage it from the first time.

Once the connection with the block will be installed, set the path in the program to the finished firmware and click on the "Download Flash" button.

Disable cable. Install the block in the car.

Turn on the ignition, wait up to 5 seconds, turn off the ignition.
All - chip tuning is made. You can run the motor and check the result of flashing.

All information lost when the power is turned off, will independently restore after a while. No other action after installing the electronic control unit do not need to be performed.

Advantages and disadvantages of chip tuning do it yourself

A person who is not familiar with the basics of work modern engines internal combustionmay scare and puzzle cons chip tuning. Let's look at the pros and cons of chip tuning.

The advantages of the engine chip-tuning include:

A noticeable decrease in fuel consumption and increasing engine power.
Increase the torque of the power unit.

Among the minuses of flashing can be noted:

Reducing the resource of the diesel engine with an aggressive driving style.
Reducing the gearbox resource.
The ability to damage the chips during incorrect connection, attempts to install inappropriate versions of firmware, performing operations with errors when changing the parameters and install the firmware with your own hands.

Therefore, to the question of whether the chip tuning is harmful to the car engine, each car owner must answer himself. It all depends on the goals of flashing, ride style, timely error diagnostics.

It should be understood that the installation of a finished firmware or editing existing versions is common ways to reduce fuel consumption on cars with gasoline, diesel, GBO. But even in the simplest programs you will not find the parameters that allow you to directly change maximum speed Or remove the speed limit, fuel consumption, etc. In commercial programs, you can change the engine's behavior in various modes, but change the parameters without minimal knowledge that it will give - far from the best wayIf you do not know the basics of the engine tuning chip car. It is better to use ready-made firmware - economical, power, etc.

Chip tuning diesel engine pluses and cons is actually the same as petrol motor. Only among the minuses of chip tuning can be noted the negative impact of changes in the parameters on the TNVD fuel pump.

Efficiency chip tuning: whether to do

Note that:

Nobody will say how the tuning chip affects the engine resource during self-perflash. The official factory firmware is a proven and repeatedly tested by the manufacturer's software product, which uses the parameters recommended for a particular engine.
Refracting and changing even individual parameters can significantly affect automatic transmission. For example, a significant increase in the maximum torque can quickly deduce the automatic box.
The manufacturer knows how to increase engine power without negative consequences - numerous studies are held, the plant is warranty for increasing power by changing the parameters of the motor.

If all this does not stop you, you can safely start tuning with your own hands. The main thing is to study the forums about your car, download the necessary software and firmware, buy an adapter for connecting a laptop to your ECU. You can always download the factory firmware (roll back) if not independently, contacting the car service.
