i'm planning on getting a spare 98 pcm for my firebird. my original is currently getting worked on getting un-bricked. when i plug the spare pcm/vcm and do a read file, the software will ask if i want to license the pcm or not. once i commit and license the pcm/vcm and save the hpt file, this is where im uncertain. can i upload my current tune from the original pcm/vcm and if so when i do the flash, should it be a full write or calibration only? if i cant use the tune from my original pcm/vcm then i can just update the spare tune to match my current tune which then goes back to the flashing part, should it be a full write or partial? i understand after that i can just do calibration only and not the write entire calibration otherwise risk bricking the pcm.

i tried searching but perhaps i wasnt looking in the right places.
