CAN BUS Compatibility

---

The E34/E32 the M60 originally came in did not communicate with the rest of the vehicle via CAN BUS. BCS LPC8 supports the early canbus based E series like E46 though.

16/12/2022 -
• E36/7 - compatible with BMWs of similar vintage
• E46 - compatible with BMWs of similar vintage
• E39 - compatible with BMWs of similar vintage
• E38 - compatible with BMWs of similar vintage
• E85 - compatible with BMWs of similar vintage


Additionally custom CANBUS is possible on the powertrain bus or the spare secondary CANBUS

Options at ordering
