What is ECU Re-Mapping?

The Engine Control Unit (ECU) is a small computer which runs the engine and it controls ignition timing, air/fuel mixture and imposes limits on speed and revs.

These variables are displayed as a ‘map’ and can usually be modified via OBD (On Board Diagnostics) programming without needing to remove the ECU from a vehicle, this is the process referred to as remapping.


Performance Remap

A Performance Remap results in better response from the engine, with increased torque and power of up to 30%. Throttle response will be improved and the rev range will be enhanced. Power delivery also tends to be smoother, making for both a more enjoyable and safer driving experience such as easier overtakes or motorway performance..

Economy Remap

With our economy remap, most vehicles can achieve a lower rev range, resulting in fuel savings of up to 15%. During normal driving, fuel economy will tend to be better which not only decreases the cost of fuel that you will have to pay, but it also minimizes your carbon foot print.

Blend Remap

Alternatively, some people prefer a blend of both our Performance and Economy Remaps, which results in smaller gains throughout the performance of your engine.
