ECU Remapping

An Engine Control Unit (ECU) is an electronic component, normally based around a single chip microprocessor housed within the vehicle. The ECU in the vast majority of modern vehicles has one fundamental function; to control basic engine operations; including (but not limited to) fuel mixture, ignition timing and engine idle speed.

Mass production for global markets has left the vast majority of ECU maps standardised, which has subsequently resulted in vehicle performance statistics often being set at an average level in order to meet basic manufacturing requirements. More and more people are seeing the benefits of engine remapping.

In the UK, where road surfaces and service quality are generally good, ECU remapping gives us the opportunity to modify engine function, eliminating restrictive elements and removing many of the standardised limitations enforced by manufacturers, maximising your vehicle’s performance.

Through engine remapping of both petrol and diesel engines we can:


    • Improve Fuel Economy (MPG)
    • Increase Engine Power
    • Move Engine Power & Torque bands to more usable positions.
    • Adjust fuel and air mixture ratio
    • Maximise turbo boost
    • Increase Engine Torque
    • Eradicate turbo limiters
    • Improve ignition timing
    • Increase valve control


Diesel Particulate Filter (DPF) is an essential device, fitted to most modern diesel engines. Its primary function is to remove dirt, impurities and other particles from the exhaust gas of diesel engines. For the most part, filtration is successfully carried out in order to abide by various global carbon emission standards.

The molecular structure of diesel denotes that there are more combustion by products inside the exhaust gases of diesel than contained in petrol combustion. The DPF is built into most modern conventional diesel engine exhaust pipes to catch these excess by product particles.

If a blockage develops in the DPF, it will stop it performing to its required level and the performance of the vehicle begins to suffer. This will increase exhaust pressure, forcing the engine to work harder in order to fight against the restricted flow, resulting in decreasing fuel efficiency, loss of engine power and eventually complete engine failure.
