Remapping your engine. Better performance, Improve your fuel consumption

Background

The engine control unit (ECU) of a vehicle is a computer that controls how the engine works.

The default settings (also known as maps) – are not necessarily the best they could be, as manufacturers who sell their cars around the world have to take into account different climates, laws and varying quality of fuels when they program the software.

Some vehicle manufacturers are also known deliberately to limit the performance of their cars through the ECU so they can release faster models at a later date, with just a few software changes and a much higher price tag.

Vehicle remapping is basically the modification or replacement of the manufacture’s default software on the ECU.

Speed and power

Remapping is intended to make the most of your vehicle’s capability by overwriting the ECU’s default settings with new software which is programmed to enhance the vehicle’s overall performance.

Previously, the process was called ‘chipping’ and involved the removal of the main microchip from the ECU, which was then replaced with a modified chip.

When your vehicle is remapped, the altered software is plugged into your cars serial port (or OBD port) which then overwrites the engine map with the new version to enhance engine performance.
If the remapping is successful, you should notice an immediate improvement in the speed and power of your vehicle.
