Identification and evidence
ACTRONICS' ECU catalogue lists Bosch Motronic MP5.1 and MP5.1.1 separately. This listing confirms a catalogue designation, not the pinout or fitment of an individual ECU.
Identification and scope
Retain the complete ECU designation, Bosch and vehicle-manufacturer part numbers, engine, vehicle year and market, hardware and software identity. Similar names do not establish shared pin assignments, calibration files or programming procedures. Examples above are source-scoped and are not a complete fitment list.
