VT standalone harness
Dumb question , when transplanting VT ecu and harness (L67 & 4L60E) I have no comms with scantool
I have had this problem before with VT transplants , for some reason VS ecu transplants seem to be fine.
Is there a trick to get scantool comms (Tech2) with the VT without the other modules (I believe the BCM is the Bus master)
TIA

Re: VT standalone harness
I guess the scan tool is listening for the bus master heartbeat message, which won't be there. It may be possible to get the VT pcm to spit out the BCM heartbeat message periodically, but this isn't how it's usually configured.
Re: VT standalone harness
In VT the BCM is the master. There's two flags to set for a stand alone set up. I can't remember off hand sorry.
When I do the V8 harnesses I write a VS3 calibration to the memcal. It solved a lot of issues. Maybe you could do the same with the V6
