System overview
DME S85B50
The MS_S65 is a further development of the
MS_S54 (MS_S54 HP, M3 CSL) that was
used to control the S54 in the E46 M3.
Additional functions used for the first time at
BMW were implemented to facilitate the use
of the S65 engine management on the
S85B50:
Two-stage selectivity of the maximum
engine power output
Transverse force-dependent control of the
electric oil pumps
Requirement-controlled fuel delivery with
variable fuel pressure
Knocking and misfiring detected by ionic
current technology.
