ECU firmware from A to Z: Improve the dynamics of the car yourself

Each modern car is equipped with a control unit. This device is designed to ensure the correct operation of the engine and all its systems. What is better to use the editor of the ECU firmware, how is the firmware of the blocks of cars do it yourself? You can find out about it below.

What is firmware?

What is the computer firmware, as such a device correctly reflash when connected to the diagnostic connector with your own hands, what use the programmer for chip tuning and equipment? Reprogramming ECU is the process of reconfiguring the motor control unit with all calibrations. The firmware represents the program of programs recorded in the memory of the engine control unit, with which its operation is controlled.

If the driver decides to carry out a chip-tuning car, the ECU is reset. Tuners interact with the elements of the engine control unit (calibration) to control the combustion of the combustible mixture and the operation of all adjusters of the unit.

In some cases, when conducting a chip tuning, using the editor, only a change in program code is made. But this happens less often than making changes to calibration. The firmware of the control unit can be located or inside the processor, or on an external board, it all depends on the engine and car model.

Moving ECU Masters in the field of chip tuning can be made using various programmers and equipment. The price of such equipment for chip tuning is high, but using such programmers is the ability to add major adjustments to the operation of the unit. Chip tuning itself with such equipment with pinout, calibration and programmer can be better, if the flashing is made by a qualified master.

Note that the type of interface that is used in the chip tuning for the firmware does not play roles. The specialist must be sure that if necessary, it will be able to reprogram the device and restore the factory settings for the engine control unit programmer. In addition, it is not necessary to forget that annually automotive manufacturers improve the system of protection against theft. And this, complicates the work of a chip tuning specialist. Most cars released until 2008, with a chip-tuning with pinout and calibration, there is no possibility to reconfigure the device without dismantling it.

What firmware happens?

Today, there is a huge number of different manufacturers of equipment programmers for flashing the engine control devices. American and German manufacturers are most famous and in demand, but in Russia recently growing the number of companies engaged in the release of programmers. This is due to the distribution of vehicles on the territory of the former CIS vehicles with turbodiesel and injectionboxes, as well as modern engines control units. But as a result of the fact that automotive manufacturers originally equip the car with modern protection against hijacking, domestic equipment programmers sometimes do not allow to reflash the ECU.

What gives flashing?

If the equipment chip-tuning was performed correctly, then you will feel changes in the operation of the motor immediately, at the first trip. A competent procedure of chip tuning allows to achieve a smooth and smooth operation of the unit, with the result that driving becomes more comfortable. In addition, the calibration and flashing of the engine control unit will increase the power of the motor, as well as increase its torque.

These parameters contribute to improving the vehicle dynamics, in some cases you can even achieve a decrease in fuel consumption. But it is not necessary to chase at elevated power and constantly reconfiguring the equipment, as this can lead to undesirable results. Moreover, do it yourself, without having experience, as the computer can fail.

Depending on the programmer and control unit, during the procedure of chip tuning and hijack protection, you can change the calibration from which the operation of the unit will depend on. In fact, adjustments may be subject to thirty to a thousand calibrations. Experts change the CSD settings, the combustible mixture supply parameters, the start of the motor, etc. Edit is made using a diagnostic programmer connected to the cable to the connector. Dismantling and dropping a computer board is not required. Depending on the car, it is impossible to achieve improvement of parameters using the programmer and connect it to the cable connector.

When reconfiguring the computer, the factory parameters, in particular, the protection settings from theft are stored in memory. Therefore, if the chip tuning process is carried out correctly, you can always return to the standard parameters. Note that software and programmers from eminent brands should be applied for self-reconfiguration.

How to flash with your own hands?

Equipment

Before you decide to discharge the ECU with initialization and its firmware, you must familiarize yourself with one of the main components of this process. But it is about the editor for the car. The editor is a special program designed to make changes to the computer settings. If you decide to produce this process yourself, you must prepare at least one editor in advance.

Today, to purchase the editor to adjust the computer files is not a problem. You can find editors from various brands and for various purposes.

Among popular can be allocated:

1. Delphi MT60. The MT60 version is universal, since it is suitable for editing most devices, including Mikas from 7 to 11 version. You can purchase MT60 for Mikas 11 in any specialized store.
2. OpenBox. After connecting the hardware cable to the computer connector, you can use the OpenBox editor. OpenBox one of the common options. OpenBox - Universal editor, suitable for blocks January, Bosch and Mikas 11. In practice, OpenBox interacts with Mikas 11 and other computers, allowing you to increase the protection against hijacking and improve other parameters.
3. In addition to OpenBox, reconfigure Mikas 11 from the hijacking after connecting the equipment to the connector through the cable using the chipexplorer utility. Like OpenBox, this program is suitable for Mikas 11 and other ECU.

To set up Mikas 11 from the hijacking with OpenBox, you will need a special module that connects to the device through the cable. The cable connector must correspond to the diagnostic output. The procedure for setting up Mikas 11 or another computer using OpenBox is carried out in accordance with the instructions.

What do you need to know?

What you need to know about flashing computer Mikas 11 or another to increase hijacking protection? By purchasing the editor for Mikas 11, you must check the contents of the package. Included, not only a program that will increase the protection against hijacking, but also a USB key that looks like a conventional flash drive. If it is not in the kit, you will not be able to use the program. It is desirable that a license is to the editor - depending on the manufacturer, it can be either one year or one and a half.

Specialists they do not advise you to do this yourself - it is better to give to those skilled in the art, not to get on dear repairs.
