Car Engine Turning Service In Cheltenham


Tuning your cars ecu is the modern day equivalent of tuning your engine. Vehicles manufactured since 1999 are controlled by an onboard computer, also known as the engine control unit (ecu). The ecu controls a multitude of different engine functions such as ignition timing, fuelling and boost pressure. Within this computer a file stores the manufacturers settings that have been fixed to allow for build tolerances into their engines and to comply with emission targets.

We are factory trained car mechanics – using manufacturer spec equipment.
