ECU Remapping Services


Remapping is designed to improve performance and economy of your vehicle overall. Our expert team at Xtreme Tuning in Birmingham, have a wealth of experience in providing remaps for a variety of vehicle types.

Whether your vehicle is 5 years or even a decade or two old, your vehicle will likely be fitted with an Electronic Control Unit (ECU). This is the ‘brain’ of your vehicle, which controls various engine functions such as fuel mixture, ignition timing and turbo boost pressure. These, (where fitted) pre-set functions are programmed into the vehicle at the factory, prior to sale.

Pre-programmed, or ‘one size fits all’ factory settings, are structured to ensure vehicles meet a range of emission standards. These parameters depend on where the vehicles are sold, such as ensuring a vehicle can withstand extreme conditions, or high or low temperatures, in addition to variations in fuel quality and other variables.

Yes. Very important. A remapping counts as a vehicle modification.

When conducting remapping services, we only ever work within the possible vehicle parameters possible. Generally, vehicle remapping is designed to improve the drivability of the vehicle, and not just outright engine power.

Yes certainly! Prior to conducting the remap, we create a backup of the original ‘factory’ ECU software settings and retain it, in case a customer may want their vehicle returned back to its original state at a later date.
