    06+ were wonky, probably won't work with DHP.

    04-05 are the only ones you can really use, and while you're there grab the stuff to make an off board. Obd2 plug from inside the car and the PCM plug, blue one on the left IIRC. Just grab them all to be safe.

    Then a +12vDC power supply from almost anywhere and build yourself an off board. Stop bricking PCMs lol

    Have instructions on how to make that off board? I wired it up the same way it showed in a post here by explicit-spade but when I go to try and read it with HPtunner it says Vehicle power not detected. I have it connected to a +12v /1.5 amp power supply.
