Bosch Me711 Pinout -
The Bosch ME7.1.1 is a versatile engine control unit (ECU) used extensively in high-performance and luxury vehicles, particularly within the Volkswagen Audi Group (VAG) and Porsche. Understanding its pinout is crucial for automotive technicians and enthusiasts performing bench flashing, tuning, or ECU diagnostics. Bosch ME7.1.1 Essential Pinout Table
- Never assume grounds: The ME711 is extremely sensitive to bad sensor grounds (pin 41/42).
- Check pin 80 before blaming the ECU: No Terminal 15 signal = no communication.
- Tuning requires boot mode: Unlike ME7, you cannot flash via OBD without a BDM or boot pin manipulation.
Note: Many technicians reference pin numbers by the ECU schematic (1 through 121 consecutively). For simplicity, we will use the consecutive numbering (1 to 121), as this is how tuning software (WinOls, ECM Titanium) and boot pin diagrams refer to them. bosch me711 pinout
For standard bench connections, the following pins are used: Pin 3: (Terminal 30 / Constant Power) Pin 21: (Terminal 15 / Ignition Power) Pin 1 & 2: Ground (Terminal 31) Pin 43: K-Line (Data Communication) Pin 60: CAN High Pin 58: CAN Low Pin 62: Often used as an additional signal in some variants Connection for Boot Mode & Programming The Bosch ME7
