Engine Management - Theory & Operation: Introduction: Notes

The Range Rover Petrol Engine Management System consists of the Bosch ME7.2 Engine Control Module (ECM) controlling the BMW 4.4L V8 M62 engine.

ME7.2 is a development of the Bosch M5.2.1 Engine Management System used on the Land Rover "Thor" V8 engine, the major difference being that ME7.2 is a "drive-by-wire" Engine Management system, i.e. ME7.2 has electronic throttle control.

Another significant system difference is the extensive use of a Controller Area Network (CAN) system to provide the interface to other vehicle systems.
