Idle Speed Setting – CO Adjustor
The BMW DME M1.1 (and similar, 1.2 and 1.3) is an early Bosch Motronic ECU, used on all of the 6 Cylinder BMWs up until 1990, and a few more after that.
M1.1 and M1.3 was used on the M20, M30 and M40 engines, whilst M1.2 was used on the S38 and M70, which are the early E34 M5 engines and the early V12s.

Multi Function Steering Wheel: Button
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.

Temperature Sensor Signal- Radiator Outlet
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

Injection Pump Control Unit
DDE 3 is the BMW name for the ECUs used on the M47 range on Diesel engines, also known as he Bosch EDC15. These are 4 Cylinder diesels, used in the E46 320d, and uses Common Rail Injection. Common Rail systems use a high pressure fuel rail with diesel injectors, as opposed to the mechanical injection systems, or the PD (Pumpe Düse) system where each injector also acts as a high pressure pump.
