OK guys I have recently purchased a 2011 Cadillac Escalade for a Duramax swap. I have a 2006 LBZ complete drivetrain I was wanting to use. My problem is the LBZ won't communicate with the BCM of the caddy because of different communication protocols. If I run the LMM ecm it will work but I'm not sure on the engine programming side if you can control an LBZ with it. If this is possible I will use the LBZ if not I will buy an LMM.
