As said earlier in this thread, the wiring is a bitch. I have never heard of anyone who has done it, but I think its possible. But If u want it to work, u will have to get the abs sensors from an e46 aswell, cause the ecu is dependent on respons from abs sensors.
I have thought about this myself, but if I would have done this I would just thrown away the original ecu and get myself an autronic or haltech.
