Essential for sequential fuel injection. Throttle Position Sensor (TPS): Measures throttle opening.
2. Common Bosch M7 ECU Pinout Functionality (Generic Overview)
The Bosch M7 series electronic control unit (ECU)—including variants like the ME7, MED7, and M7.9.7—is a cornerstone of automotive engine management. Used extensively by manufacturers like Volkswagen, Audi, BMW, Porsche, and Chery, understanding its pinout is essential for diagnostics, repairs, engine swaps, and performance tuning.
| Pin Number | Signal Name | Description | | --- | --- | --- | | 1 | Fuel Injector 1 | Output to fuel injector 1 | | 2 | Fuel Injector 2 | Output to fuel injector 2 | | 3 | Ignition Coil 1 | Output to ignition coil 1 | | ... | ... | ... | Bosch M7 Ecu Pinout
: These units often feature three modular connectors with a total of 112 channels. They comply with EOBD standards for emission diagnostics.
(Exact pin numbers differ by variant; this section lists groups you will find on M7 ECUs.)
The (Engine Control Unit) is a highly reliable and versatile engine management system frequently used in a wide range of vehicles, particularly in many Korean (Hyundai/Kia), Chinese (Chery, Geely), and Russian (VAZ/Lada) vehicles. Understanding the Bosch M7 ECU pinout is essential for technicians, tuners, and DIY enthusiasts involved in engine swaps, diagnostic work, or performance remapping.

Reading or writing the flash memory (typically an AMD AM29F400 or AM29F800 chip) on a Bosch M7 ECU requires specific bench wiring. This is crucial for deleting immobilizers (Immo-Off), recovering bricked ECUs, or cloning hardware. OBD/K-Line Bench Setup
To work with the Bosch M7 ECU, you'll need specialized tools and software, including:
Monitors engine temperature.
Example A — 4-cylinder sequential injection (conceptual)
To put the ECU into bootstrap mode for firmware writing, some versions require connecting specific internal resistors (e.g., two 680 ohm resistors) while grounding certain pins during power-up. Bench Connection:
