Below is the essential pinout. NC = No Connection (unused).
Pin assignments for the drive-by-wire system (Potentiometers and Motor). Fuel Injectors: Specific pins to drive the fuel injectors. Ignition Coils: Individual control pins for each cylinder. MAF Sensor: Mass Air Flow sensor signal. MAP Sensor: Manifold Absolute Pressure sensor. 4. Bench Programming / BDM Pinout
For tuning, the ME7.1.1 requires connection to a BDM (Background Debug Mode) tool to read/write the flash memory (29F400 or similar). Usually VCC or Ground, depending on the tool. Reset: Required for flash access. Clock: Required for flash access. bosch me711 pinout
Here is a reference table for the Bosch ME7.1.1 ECU, based on a consensus from professional automotive communities, which are considered reliable sources.

If your OBD-II scanner says "No communication" but the ECU has power (pin 80), check the CAN bus. Resistance between pin 15 (CAN Low) and pin 16 (CAN High) should be approximately (due to two 120-ohm terminating resistors in the cluster and ABS module). Open circuit (>100 ohms) means a broken wire.
