The engine management system of the new Mercedes-Benz S-class has been completely redesigned and fully meets the demands of the new top models. The ignition management, fuel injection management and air management system components are interlinked by a high-speed serial databus, controlling functions are performed in real-time and parallel. Open system architecture and a suitable communication structure indicate how engine management systems will be designed in the future.

The electronic fuel injection and ignition control units on the engines of the new Mercedes-Benz SL roadsters were further developed on the basis of the tried and tested control units. Introducing a communication interface between both ECU's has permitted coordinated functions such as maximum speed limitation. The ignition control unit contains an adaptive closed-loop anti-knock control algorithm for each individual cylinder.
