ECU Remapping

What is ECU Remapping ?

Most vehicles have what is called an ECU (or Engine Control Unit) which is a computer that controls how the engine works.

Vehicle manufacturers automatically de-tune the engine by setting the software on the ECU to a default setting before sending the vehicle out. This is done because the manufacturers sell their vehicles all over the world, this means that the software settings inside the ECU have take into

account the different climates, laws & restrictions and the varying quality of fuels.

ECU Remapping is modifying the original software in the ECU to allow the engine to run at it’s optimum without any restrictions, this allows the engine to run as it was meant to.

Most of the remapping that we do is done by plugging special reading and writing equipment into your cars serial port (or OBD port) which then overwrites the original engine software with a new version to enhance the engine performance, we also do Chip Tuning, BDM, Tricore and other methods of doing the remap, if you would like more information about wht is involved in ECU Remapping then continue reading below which goes into quite a bit of detail.

OBD Remapping 

This is the easiest way to remap your vehicle for us and is usually the cheapest method for you, it is done by connecting our tuning tool to the OBD port located within your car and downloading the tuning parts within. We will then open this file with our tuning software and make all the necessary increases where required. When we have completed all the necessary changes required we will then upload the new map back into your vehicle through the OBD port and then the remap is complete.

Tricore Remapping

With this method we would have to remove the ECU from your vehicle and open it up on the bench, we will then make a simple connection to the circuit board that will bypass the chip protection that has been enabled by the manufacturer, this is something that was introduced in 2009 and implemented on a lot of 59 plate registered cars and onwards (we call this tricore protected), we will then perform the same procedure as we do with the OBD remapping, when we have completed this process we will then replace the ecu back in the vehicle and then the remap is complete.

EEprom Remapping

Whit this method we will need to remove the ECU the same as we do with the tricore system above and once we have it on the bench we will need to unsolder the chip that contains all the tuning software and use a chip reader/writer to copy all the files that are contained in the chip, we will then make all the necessary changes as with the above methods, when thi s is complete we will then write the mapsback to your chip, (some chips are not rewritable so we would need to replace it with the same equivalent) we will then reinstall the ECU and then the remap is complete.
