Company description
Remapping is intended to make the most of your car by overwriting the ECU's default settings with new software which can be programmed to enhance the overall cars performance. This is known as vehicle remapping because the ECU is essentially a program that controls how the engine works. When your car is remapped, the tuned 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.
