Modern vehicles are controlled by an Engine Control Unit (ECU), which manages fuel delivery, turbo boost, throttle response and power output. Factory settings are often conservative to suit global conditions, emissions targets and fuel quality.

Engine remapping allows these settings to be optimised for real-world driving. Depending on the vehicle, remapping can improve throttle response, increase torque, enhance power delivery and in some cases improve fuel efficiency. All remapping work is carried out following detailed assessment and car diagnostics in Swansea to ensure the vehicle is suitable.
