i cant make this any clearer, the pcm dont know whats what, its been edited and re flashed. use a different tuner and the pcm dont care one bit. its just being read and written to by what ever you own.
like i said as well, guys with hpt have sent me their pcm for the cat test kill. they read and wrote to it long before i got it and made the changes with tt and dhp. then they re read the pcm save and use that new to them file in hp. cause the changes for a cat kill are hidden in hpt, but its still in the pcm file.
