PNPECU Link FuryX M52 MS41 solution V4

---

This page refers to version 4 PNPECU M52 Link FuryX solution only. Make sure to check the adapter tag for your version.
This is not compatible with 320i Siemens ECUs which have different wiring, please contact us if you want such an adapter.

15/2/2023 - Version 4 is latest.

PNPECU has developed the M52 solution to satisfy customer requests to allow the M52 engine to be fully controlled

M52 OEM Sensors Usage

---

• MAF is not used
• Lambda sensors are not used
• Air temp sensor is not used - new fast sensor is supplied
• Camshaft sensor is not compatible - recommended is to fit a M54 sensor - not crucial for normal operation, vanos still works. The original sensor must be disconnected as the adapter is pre-wired for a M54 sensor / M50 vanos sensor.


• Coolant temperature - used as OEM
• TPS sensor - used as OEM
• Vehicle Speed Sensor Rear Right - used for vehicle speed
• AC signals from vehicle - used as OEM
• Knock sensors - used as OEM

M52 OEM Actuator Usage

---

• Ignition coil wiring - see options below for more details
• Tachometer signal
• Fuel pump relay
• Idle control valve
• Vanos advance
• Check engine indicator
• AC Compressor relay
• Fuel consumption output

CAN BUS Compatibility

---

The E36/E34/E38 the M52 originally came in did not communicate with the rest of the vehicle via CAN BUS. However, thanks to Link it is possible to fit the engine into other cars that require information via CAN BUS

16/12/2022 -
• E46 - compatible with BMWs of similar vintage
• E39 - compatible with BMWs of similar vintage


Link provides OEM BMW CAN BUS output for the above BMW vehicles, but since it was never developed for BMW applications it is not complete, but the main base functionality is there like tacho and coolant temp. It also supports a vast array of other cars which a M52 can be fitted to thanks to Links CANBUS options. Refer to the link ecu software help for available CANBUS outputs.
