The ECU used in the 2KD-FTV engine is likely the 89663-0A150 or equivalent. Here is a partial pinout diagram:

| ECU Pin | Function | Action | | :--- | :--- | :--- | | | MAP (Boost pressure) | Intercept this. You will add 0.5V to fool the ECU into thinking boost is lower. | | B10 | MAF (Airflow) | Cut and feed modified signal. (Less common on 2KD; usually just MAP) | | C10 & C11 | SCV (Rail pressure) | DO NOT CUT. Tap only to monitor. Modifying SCV kills fuel pumps. | | B22 | Common Rail Pressure (VCM) | Intercept this. Lower the voltage by 0.3V to increase rail pressure. | | D1 & D2 | CAN Bus | If using a high-end module (e.g., Steinbauer), you read CAN here. | The ECU used in the 2KD-FTV engine is
