You can load bin files into EFILive also. Doesnt have to be ctz.

I have a 21 ecm trying to make it work on my 22. Learning a lot from this thread.

So you put the truck's original VIN in the 20 ecm? Did you finally do it successfully with efi live? I've never heard of "wiping the keys"??? I thought you just reprogrammed them by having them in the truck when doing it???

I know it's being done. I just don't know how..... yet.

I can leave ecm virgin, anyone with witech can then put vin and learn key
