The ME7.1.1 is part of the Bosch Motronic family, managing fuel injection, ignition timing, and electronic throttle control (drive-by-wire). Often uses ST10F275 or similar microcontrollers. Communication: Supports CAN Bus and K-Line for diagnostics.
The Ultimate Bosch ME7.1.1 Pinout Guide: Bench Flashing, Bootmode, and ECU Wiring
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.
Similar architecture but may use different internal processor layouts (e.g., ST10F275) requiring specific "lay-by" pin identification for direct connections. bosch me711 pinout
Connect this boot point to a solid using a 1k-Ohm resistor. Turn on the +12V power supply (both Pin 62 and Pin 3).
The Bosch ME711 is a popular engine control unit (ECU) used in various vehicles. Understanding the pinout of this ECU is essential for developers, engineers, and enthusiasts working with engine control systems. In this article, we will provide a detailed overview of the Bosch ME711 pinout, including its pin configuration, functions, and applications.
| Pin | Function | Description | | :--- | :--- | :--- | | | EGAS Potentiometer | Electronic Throttle Signal (Where applicable) | | 2 | Ground (Power Stage) | Ground for Output Stages (Injectors/Ignition) | | 3 | Fuel Pump Relay | Control signal to activate the fuel pump | | 4 | Vehicle Speed Signal | Input from speed sensor/cluster | | 5 | Cruise Control Switch | Input for Cruise Control (if equipped) | | 6 | Ground (Sensor) | Ground reference for sensors (MAP/ The ME7
: Typically requires a direct connection (often using a resistor like
Ensure your power supply is maintaining at least 12.5V under load. Low voltage will prevent the ECU from initializing communication protocols.

The ME7.1.1 ECU has multiple different printed circuit board (PCB) revisions. Therefore, the physical point where you short Pin 24 can vary. On some boards, there are dedicated solder pads. On others, you must connect directly to the leg of the flash chip itself. Always double-check your specific ECU's board layout before attempting this.
