Bosch Me711 - Pinout
Bosch ME711 Pinout: A Comprehensive Guide
The Feature: To trigger this, you must open the ECU case and ground Pin 24 of the flash chip (or a corresponding test pad on the PCB) for approximately 2–5 seconds while applying power to the main pins.
Preparation: Open the ECU casing to access the internal PCB. bosch me711 pinout
Adding a Wideband Lambda (Analog Output)
The ME711 often uses a narrowband pre-cat O2 on pin 4. If retrofitting a standalone wideband (like an AEM or Innovate):
The ECU usually has two main connectors. The pins are numbered on the plastic housing. Ground (GND): Pin 1 & Pin 2 Permanent Power (+12V): Pin 3 (Terminal 30) Ignition Power (+12V): Pin 62 (Terminal 15) K-Line (Communication): Boot Mode Pin (For Flashing) To put the ME7.1.1 into (required for EEPROM reading or full recovery): Locate the flash chip or the processor inside the ECU. of the flash chip through a resistor while powering on the ECU.

In conclusion, the Bosch ME711 pinout is a complex configuration that requires a thorough understanding of its various pins and functions. This article provides a comprehensive guide to the ME711 pinout, including its pin configuration, functions, and applications. By understanding the ME711 pinout, developers, engineers, and enthusiasts can design and develop more efficient and effective engine control systems.
- Keep the crank sensor wiring (78/79) – It’s a standard 60-2 trigger wheel.
- Keep the cam sensor (pin 73) – For sequential injection.
- Repurpose injector outputs (31-34) – These are low-impedance capable in ME711 (supports 2-3 ohms).
- Drive by wire (E-Gas): The ME711 throttle motor is controlled via H-bridge outputs (not listed in simple pinout – requires throttle motor pins 89 & 90). For standalone, either replace with a cable throttle body or use a CAN-to-analog converter.
If you are connecting the ECU on a bench for diagnostics or flashing, the following pins are generally standard across many ME7.1.1 units: Pin 1 & 2: Ground (GND) Pin 3: Switched Ignition (Terminal 15) Pin 21 & 62: Constant Battery Power (Terminal 30) Pin 43: K-Line (Diagnostic communication) Can't get 24V VR6 (ME7.1.1) 022906032CS into boot mode Keep the crank sensor wiring (78/79) – It’s
Alfa Romeo (MED7.1.1): Uses a similar physical shell but features different pinouts for direct injection (MED) vs. standard injection (ME). Troubleshooting Connections If you cannot communicate with the ECU on the bench:
