I have a 2007 6.2 and 6L80 swap.E38 PCM. Dakota VHX and BIM. When the BIM is plugged into the OBD2 port, the check engine light flashes, trans wont shift past 3rd gear. If I unplug the BIM module the truck works as it should. Dakota has given me every tech tip they can think of. Nothing helps.

Anyone else run into this issue? I'm totally stumped. The BUS checks out fine. I have no serial data wire in the OBD2 port.
