Yeah I'd be happy to share notes one the GM stuff. I recently only discovered that all OS in the Corvettes, and possibly a couple others LS, used a completely different ArbID structure. So I've been working on that protocol the past couple months. Think I have a check engine light byte identified for it, but not yet for protocol above..
Sending you a PM with my contact info. Think I've stumbled across your work on the BMW swaps before.
Cheers
