Dupec Ecu Pinout !exclusive! Jun 2026

Some Dupec units come pre-wired with a Nissan gray connector or a Honda blue connector. In this case, the is not determined by the ECU manufacturer, but rather by the car manufacturer . You simply need a factory service manual (FSM) for the vehicle to identify what each pin on the harness goes to.

(like the AMD 29F010) to solve "no start" or flashing spanner light issues caused by faulty transponders or immobilizer modules. Compatibility : Because it mirrors the Bosch Motronic 1.3/1.5

(MAP Signal), A8 (TPS Signal), B11 (Lambda/Oxygen Sensor). Actuators B6 (Fuel Pump Relay), C11/C15 (Injector Control). Communication Diagnostic pins often use the K-Line for OBD interaction. Troubleshooting and Modifications Opel Corsa lite Dupec 1.4 Immo Bypass Chip - Motokey dupec ecu pinout

Disclaimer: Always verify these pins with a multimeter in continuity mode before applying power. Dupec manufacturing batches vary.

A wrong pinout can destroy the ECU. Common scenarios requiring an exact pinout include: Some Dupec units come pre-wired with a Nissan

Before you can use a pinout, you must identify the connector style attached to your Dupec ECU.

Before diving into the pinout, it is critical to understand what the DU PEC actually is. (like the AMD 29F010) to solve "no start"

The following pinout refers to the standard 55-pin configuration for the Dupec/Motronic ECU used in the Corsa 1.4i: Power & Grounds Pin B1 & C16 : Battery Voltage (Positive). : Ignition Input (Switched Battery Voltage). Pin A11, A12, B10, C12, D1 : Main Ground (Earth). : TPS and ECT Ground. Sensors (Inputs) : Rotation Sensor Signal (Crankshaft Position). : MAP Sensor Signal. : TPS (Throttle Position Sensor) Signal. : VSS (Vehicle Speed Sensor). : Lambda (Oxygen) Sensor Signal. : ECT (Engine Coolant Temperature) Sensor Signal. : ACT (Air Intake Temperature) Sensor Signal. Actuators (Outputs) : Fuel Pump Relay Control. : Ignition Coil Control (Cylinders 2 and 3). : Ignition Coil Control (Cylinders 1 and 4). : Injector Control (Cylinders 2 and 3). : Injector Control (Cylinders 1 and 4). Pins C5, C6, C8, C9 : Idle Air Control (Stepper Motor). Common Issues & Modifications Immobilizer Bypass : A common fix for these ECUs is an Immo Bypass chip
