GMLAN / CANbus messages for E40 (LS2 / LH6)

[Bayley]

Does anybody have high speed GMLAN (CAN bus) message definitions for a 2006 E40 controller? I'm trying to convert the GM messages into BMW CAN messages and while I've been able to reverse engineer the BMW side, I'm not having much luck with the GM side.

These are the messages that the E40 controller is sending out:

Plan-B is to request the information I'm looking for (engine RPM and coolant temp) through OBD-II PIDs, but that's a clunky extra layer of coding and will never be as fast as reading the raw cyclic message.

Thanks

I looked though the GMLAN Bible online. It's pretty sparse and doesn't contain anything specific to the E40 PCM. It's a great concept, but really lacking in content.
