I am by no means trying to say I know what I am doing entirely. I farmer rigged my PCM to my wiring harness for my 5.3 on Sunday. Plugged my ODBlink MX+ into the OBD port. And yes after some trial and error. I was able to pull the file out of my PCM with PC Hammers and OBDLink MX+. So if you have computer or laptop handy you can do that as well.

Understand this tread is old as well and may mean absolutely nothing.
