Hi, I have a BMW 540 from 1999 and i'm looking into what options I have regarding a standalone. The thunder seems like a perfect fit with dual knock, vanos control etc given it is a V8. But is it possible to maintain the cars creature comfort and security features that is communicating over CAN? instrument culster, climate control, abs and airbag are some of the bare minimum of CAN modules that needs to be in working order. How would you approach this?
