Electric Fan
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.

DDE Error
This is an Updated version of the previous DDE 2.1, and was introduced in 1995. This system was used on the M51TU engines.
Injection Pump Signal
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.
