When you get to the download pcm Select try ALT keys, and unselect use high speed.

If that does not work, unplug from the truck, and shut the EFI program. Now replug back into the truck. Next open EFI and try. Sometimes it does not recognize the cord if you have the program open then plug into it.

The last time I did a LB7 it took 4 tries. I have no idea why, but it should work, when it messes up, you can tell after just a few seconds. If the green bar starts moving you should be OK.

It really does not need to be liscensed to the vehicle to read the program, just to install one
