I'm trying to program Operating System 12212156 and a cal into a 0411 PCM out of a 4.3L V6. I've done this before without a problem on a different car. This time I only have the option to flash the cal file.
Any ideas as to why I can't flash the OS and Cal?

Close all instances of EFILive. Plug your V2 into the computer, wait for the V2s LCD screen to display the main page. Now open the tune file and the full flash arrow will appear.
If it still doesnt work, try rebooting your PC first then plugging the V2 in.
Ahh yes. The I.T. approach. Worked like a charm.

Glad it worked, there are some features that arent available unless you have your V1/V2 plugged in before you start the tune tool.
Good job...:cheers:...I was wracking my brains.
