using 05/06 pcm in 03
will a pcm out of a 2005 or 06 expy work in an 03?
yes, i know the engine and transmission are entirely different and will not work, my main concern is if it will play nicely with the modules on the truck like the cluster and bcm and security module. i know they are technically all 2nd gens but i dont know if there were any major changes or revisions to these subcomputers that would make them incompatible. the reason i care is because hptuners only works on 05+ expeditions and i dont think it will ever be supported, so this seems like the only real possible solution to self tuning this thing.
