M52 OEM Sensors Usage
• MAF is not used
• Lambda sensors are not used
• 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 sensors - used as OEM
• Vehicle Speed Sensor Rear Right - used for vehicle speed
• Knock sensors - used as OEM
• AC Compressor Enable - used as OEM
• AC Compressor Activate - used as OEM
M52 OEM Actuator Usage
• Ignition coil wiring
• Tachometer signal
• Fuel pump relay
• Idle control valve
• Vanos control
• AC Compressor relay
• Tachometer
CAN BUS Compatibility
The E36 etc the M52 originally came in did not communicate with the rest of the vehicle via CAN BUS. 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
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 S54 can be fitted to thanks to Links CANBUS options. Refer to the link ecu software help for available CANBUS outputs.
Options at ordering
Not everyone is going to need or want the same thing with their ECU conversion.
Ignition outputs
• Smart coils - Customer will install logic coils in place of original coil wiring
• Stock coils - Adapter housing provides ignition drivers.
ECU Model
• ExtremeX - 8 Analog inputs are spare, 5 Digital input are spare, 2 Low side outputs are spare. CAN2 is spare in multiple locations.
Injector
This is a selectable option so that the webstore doesn´t incorrectly calculate shipping cost
