Most modern vehicles contain an ECU (or Engine Control Unit) that is a small computer that controls how the engine works. Most vehicle manufacturers de-tune the engine by setting the software on the ECU to the defaults before sending the vehicle out to be sold and this restricts the power of the vehicle. Manufactures do this as they sell there cars all over the world, this means that the software settings on the ECU are defaulted for different climates, restrictions and laws. Vehicle remapping is where the manufactures firmware is modified taking away these restrictions.

Remapping a vehicle replaces the default software on the ECU by overwriting it with new software that is programmed to optimize your cars performance. This is known as vehicle remapping. When your car gets remapped the tuned software is plugged into the serial port of your car and overwritten by our computers leading to improved engine performance.
