DME Control Unit
The Motronic 1.7 and subfamilies, and the M3 and it’s variants are the next generation of BMW ECUs. The M1.7 was used on the M40, M42 and M70, the M1.7.1 was used solely for the S70, used in the BMW 850CSi. M1.7.2 was used for the M42 and M43 4 Cylinders. The M3.1 is a 6cyl ECU, used on the early M50 24v engines without VANOS. The M3.3 family were used to run the later 3.8 litre S38b38, the S50 3.0 M3, and the M60 V8s. M3.3.1 included VANOS control, and is used on M50 engines with VANOS, introduced to the E34 and E36 in 1992.

Lambda Sensor Control
MS40 was a new ECU for BMW, manufactured by Siemens instead of the previous Bosch Motronics. BMW split the M50 24v engines and used Siemens for some of the 2.0 litres, and Bosch continued on with the 2.5l.
MS40.0 is a rare ECU used on non VANOS 2.0l, and MS40.1 introduced VANOS control.
Lambda Regulation Bank 1 Pre Cat
The next generation Siemens MS ECUs introduced many of the OBD2 features. This includes Catalytic Converter monitoring and Long / Short term Fueling and Ignition Adaptation. The MS41 was used on the M52 series of engines, MS42 on the M52TU series, and MS43 on the M43 4 Cylinders.
The OBD2 P codes fault protocol was not activated in European markets on this group, as currently it was not required by law.

Misfire Cyl 5 with Cyl Cutout
The MSS52 is an M Power ECU designed to run the E39 M5, the Z8 Roadster, and also the Wiesmann Roadsters. The MSS54 is used on the E46 M3 and on some Z3Ms. The system uses an Electronic Throttle to accurately control Air intake instead of the more common Cable throttles used on earlier vehicles
