You can use a different commercially/open source available editor and read the file from a bench PCM that you flashed with your proprietary format/different software tool... You can also go hardcore and yank the flash chip and read the image with a hardware programmer. If you do the latter, be sure to reverse the byte order in the binary if you want to be able to open it in the software editors.

Gameover,

I have heard a few horror stories related to doing a cal-write on those PCMs if the OS's are different... but if it didn't 'brick' it, you should be in good shape.

Hopefully, I didn't brick it... It's actually gonna be ready to be fired up this weekend!

I ran across this problem years ago........trying to use a 5.7 pcm on a 4.3......I guess they (EFI Live) think
the risk of brickification is too high like on the E40

If the PCM is not affected by the cal only flash and does not work correctly as a V8, it is possible that it could be full flashed by a Tech2 and have all of the correct OS and segments written to it. This shouldn't require another license either.

Everything went smooth with the cal only flash....Fired right up and owner has been driving vehicle for a couple of months now...
The OS's were actually the same "16263425" 4.3 cal only flash to 5.7
