ECU Remapping / ECU Tuning

“Remapping” is a software change within a vehicle’s electronic control unit (ECU). We modify the operating parameters within the code (or ‘map’) to increase the vehicle’s performance and/or economy, without the need to change or add any hardware.

In many cases the map stored within the ECU can be accessed via the onboard diagnostics port (OBD) which is always situated within one metre of the driver’s seat. In some newer models the ECU needs to be removed for the modification to be carried out on the bench.

Once team will adjust the original calibration to maximise the vehicle’s performance, fuel economy, or a clever blend of both. Depending on the vehicle and ECU type the process normally takes less than an hour, although bench programming takes slightly longer.
