What is Ecu, How to Repair, What to Do on Ecu?

ECU is the electronic system used for the control of vehicles. It is called an electronic control unit. It provides the communication within the vehicle and reads the data from the sensors.

Use under the engine computer in new generation vehicles, there is a different computer for each module. ECUs contain microprocessors.

Generally in vehicles;

  • Engine control unit
  • Abs control unit
  • Comfort system control unit
  • Display control unit
  • Airbag control unit
  • Climate control unit (air conditioning control unit)
  • Transmission control unit

There are ram, rom, eprom, eeprom, flash memory units in the electronic card.


Ram: Holds temporary memory.

ROM: It is readable memory.

Eprom: Erasable and programmable memory.

EEprom: Programmable read-only memory.

Ecu (Engine ECU Programming)

What is the Flash Memory Unit on the Ecu?

The flash memory unit updates the software on the ecu.

In transactions changed via the software;

Chip tuning process

  • Egr fault solutions
  • Dpf fault solutions
  • Adblue fault solutions

Oxygen sensor fault solutions

For these operations, the software in the engine computer must be read. This operation cannot be performed with fault detection devices.

ECU programming devices and chip tuning devices are available for these processes.

After chip tuning, it provides power and torque increase, fuel saving and performance in vehicles.

In order to control the changes made in the software of the computer in the vehicle, the software in the engine computer is checked and the vehicle originality test with the existing file, whether the vehicle has been chip-tuned, etc. possible to view transactions.

In this case, the software in the vehicle can be read and compared with the original file.


How is the Vehicle Test Performed After Chip Tuning?

After the chip tuning process to the vehicle, there is usually a 20% to 30% performance increase in the vehicle.

In my works after tuning, the definitive test is given with the vehicle dyno.

Dynos are usually available in appraisals because they take up space and are costly in price.

You can take it wherever you want with the mobile dyno produced by Magicmotorsport. It is also possible to install on a mobile phone or tablet.

Thanks to Mobil Dyno, the control of the vehicle software test in the vehicle is provided.
