How it Works
- MMS 200:
The MMS200 series was the first Engine Control Module (ECM) series for the 12v V6 engine,
used in the Audi 100 through October 1992 production. It was adapted from the MPI Engine Management
System for the Coupe Quattro and 90 Quattro 20-Valve and included On Board Diagnostic I (OBD-I)
capabilities. The ECM itself is made by Bosch and contains an 8-bit microprocessor with 48kB system
memory.
