CAN BUS Compatibility

---

The E46 etc the M54 MS45.0 originally came in did 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 M52 can be fitted to thanks to Links CANBUS options. Refer to the link ecu software help for available CANBUS outputs.
