OK, I just bought V2 to tune my 99 Tahoe with a 0411 ECM (LS1B). It has been tuned with EFILive as a 2002 Express (L31 Engine with LS1B ECM). I have the tune file that was used. It had the wrong VIN. I went to change the VIN, but every time I try to use the V2 on my Tahoe i get one error message or another. I put a spare 4GB SD card and have formatted everything, reloaded the firmware, and reinstalled the software.
This is the file structure:
EFILive
Scan
Tune

However it keeps asking for Options.txt, and files and folders for PID files.

What am I supposed to do just to get started?
