    Default pcm swap

    im trying to put my old black box pcm into another truck, as i have it laying around from when i did my 411 swap and his computer has locked due to his crappy hypertech messing up. how do i disable the security feature to use this pcm in his truck? it will not let me do a full reflash

    I have never tried this but it is supposed to work. Make sure you have a battery charger (on low) hooked up to the truck when you do this. It is a PDF file that I got off of the MONADAX website. It is NOT mine. I am just passing the info on.
