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 Stage1 (Vehicles from 2000 to 2010)
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 (Some vehicles from 2009 onwards requires the removal of the ECU)

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.

Chip Tuning (Lots of vehicles before 2000 need the ECU removing and the chips changed)

This is the most difficult type of ecu remapping for us and is priced accordingly, with 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 this is complete we will then write the maps  
back 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.
