Ok, I completely removed EFI Live software. I then Shut down and restarted my computer. I Re Download EFI V8 and V7.5 from this thread. I then restarted the computer again. The issue continues. Even if I shut down and reopen V8 between flashes.
Pay attention to the Vin number displayed. I attached them to these file names as well. I had the same issue with the other files I posted. It will Only Full Flash a new file If I change the vin number to that file. I forgot if you do a license check in V8 it will read the Vin Of the current file programed. Service number on PCM is 12589463. Bench Harness is from EFI connection. Let me know if I can provide any other information.
