Task The electronic control unit (ECU) collects all necessary information for the engine, for example sensor signals, prioritizes them, and then goes about implementing them. Furthermore rider demands and exhaust-system requirements re-lated to the mixture composition are computed. Torque is the key factor in implementing these requests. For instance, the air-fuel ratio is adjusted in such a way that torque is provided as economi-cally and cleanly as possible. Doing so also allows active safety systems such as ABS and motorcycle stability control (MSC) to af-fect engine torque.

Function The electronic control unit is realized as a printed circuit with various types of housing possible; in this case, molded housing. It is also able to manage upcoming featu-res such as on-board diagnostics (OBD), a start-stop function, ISO 26262 (Road vehicles – Functional safety), knock control, connectivity, and enhanced user experience, enabled by Blue-tooth-compatible communication.

The molded ECU works reliably and independently of ambient conditions (vibration, temperature, tightness).
