Engine Control Module (ECM) Adaptation
WARNING: This page is about a different car, the 2017 Jaguar XJ, 2016 Jaguar XJ, 2015 Jaguar XJ, 2014 Jaguar XJ, and 2013 Jaguar XJ. However, it is still accessible from the selected car via links, so may be relevant.
The engine control module (ECM) has the ability to adapt the input values it uses to control certain outputs. This capability maintains engine refinement and ensures the engine emissions remain within the legislated limits. The components which have adaptions associated with them are:
- Accelerator Pedal Position (APP) sensor
- Heated Oxygen Sensor (HO2S)s
- Mass Air Flow and Temperature (MAFT) sensors
- Crankshaft Position (CKP) sensor
- Electric throttle
- Knock sensors
