I just picked up v2 for my 2005 lly duramax and had a dsp5 switchable tune built for it. Uploaded it and it works very well. I haven't tried to scan with it because I have no reason to.
I used the 2nd vin license for my 2010 xpress van e38 4.8L. I have successfully downloaded a tune, modified it, and uploaded it back to the pcm. I have tried logging both via bbx and pass thru logging and have been unsuccessful.
When I plug into the obdII port with the engine running and try to start the logging process, I get various messages on the dash, stability, airbag, etc. none of the gauges function, radio turns off, turn signals are non functional. The engine will stay running and it will take what appears to be snapshots of data very sporadically.
When I plug into the obdII with the engine off and ignition in on position and try to start the logging process, I get the many of the same messages, but the engine wont crank.
I have set chosen pids in v8 software and set up the v2 as much as I know how to in that program, but I am obviously missing something.
I feel like blaming the v2, but I don't know. I have 2 other gm vehicles, but I'm afraid to try to scan the others at this point. I don't know if there is any danger of messing up PCMs
Can anyone help me?
Thanks in advance
