(up to 112 channels in certain series) to handle data from various sensors and actuators. Bosch M7 Series Overview The "M" in M7 stands for , Bosch's name for integrated fuel and ignition control. : Commonly found in (Peugeot/Citroën) vehicles with TU-series engines. : Widely used in Hyundai/Kia : Frequently used in (M62TU engines) and other high-performance applications. Common Pin Assignments

The Bosch M7 ECU pinout consists of a 64-pin or 70-pin connector, depending on the specific variant. The connector is divided into several sections, each with its own set of pins and functions. The pinout configuration includes: Bosch M7 Ecu Pinout

For technicians using tools like New Trasdata to communicate with the ECU directly, specific wiring is required for and Configuration (CNF) modes: (up to 112 channels in certain series) to

Bosch M7 ECU family (including models like M7.9.7, M7.4.4, and M7.8.0) is a versatile engine management system used across a wide range of vehicles, from Lada and Kia to Polaris ATVs and Piaggio scooters. These ECUs are primarily responsible for controlling engine torque, fuel injection, and ignition timing. Bosch M7.9.7 Pinout (Lada/Europe) : Widely used in Hyundai/Kia : Frequently used
