Engine Control Module (ECM) Adaptions
WARNING: This page is about a different car, the 2019 Jaguar XJ and 2018 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
