the php custom ficm tunes incorporates inductive heat, ive used them with several different levels of reflashs and not one issue so no it wont need to be matched to the ecm/tcm but there are other reasons to flash the ecm/tcm back. i could probably do an ecm/tcm if it was mailed to me by swapping it into my truck, flashing it then removing it and shipping it back out, BUT my truck is an 06 so can flash 03-04 computers due to hardware incompatibility.
