I had a vehicle dropped off with pcm locked to a hpt box. I had previous tuner send me the hpt file that's supposedly unlock from hpt tech support can someone convert this to an efilive file or can I somehow? I can attach file if need be. Or is it possible for my to write flash over the hpt file even though I cannot read flash.. the is a 12592618 it's a engine swap btw. Thanks in advance
