Control Unit

Two water-cooled MSD87-12 control units are used. The same water tight components as those on the MSD85 (N63 engine in the F01) have been used. As on the predecessor engine N73, a primary (master) and secondary concept strategy has been implemented with the two control units. They have the same hardware, software and data records. The connected sensor system runs an automatic primary (master) and secondary identification. In this arrangement, the master is responsible for communication with the complete vehicle and the specified nominal values for the engine functions. The control unit is designed with the current software for the vehicle network with FlexRay.
