The Engine Control Module (ECM) or often called as Engine Control Unit is often known as the “brain” of the vehicle. This system enables efficient engine performance and emissions by controlling air, fuel, and spark synchronicity.    The ECM functions by receiving in data from various sensors throughout the vehicle and in return controls the actuators to provide the appropriate response against the situation. This whole set of two ways communication is made possible by an OEM coding and programming installed in the ECM. Hence the right suitable coding & programming is utmost important for the optimum performance of the Car. Kindly contact AMA auto Sharjah if you need ECM/ECU coding or programming for your German Car.
