    PCM Power supply

    Not really an OBDII tuning question but,
    Any recommendations on a AC power supply for a Pcm?
    I am making a harness to do some testing, dont really want to have a Battery and charger here, whats a good power supply to power up the PCM to do some scanning and reflashing?

      Cool, thats what I was thinking, I had made a charger years ago to keep Battery full when programming Pcm in the dealer.

      I have a few PS left to use

        yes, ATX supplies are awesome for this. i just converted the one i had in wifey's desktop...

        770watt PSU in the desktop, and like ~350-400watts for the bench supply...
        1995 Monte Carlo LS 3100, 4T60E...for now, future plans include driving it until the wheels fall off!

          770? Nice. And I thought I was going overboard with my Antec 650w Truepower Trio on my gaming system, lol. 350-400w should be an overkill for a PCM/ECM that's not running any sensors/injectors/ect.
