  • '99 SL2 PCM Swap/Megasquirt

    I just bought a '99 SL2 w/ standard trans. I went to the local car recycler today and picked up myself a PCM from a '99 SL2 AUTO because I heard that there are advantages to doing this. This weekend I plan on installing that PCM and making a homemade CAI.

    First off, will this "new" pcm I picked up work alright without throwing out random codes and putting it in limp mode? I've heard very mixed opinions. For the most part, I hear that it works great. One person said that it wouldn't work and would throw a bunch of codes at me. Also, saturn won't have to do anything to this PCM for me, will they? I should be able to hook it up and my car should start, right?

    Secondly, does anyone have some tips for installing a MSII kit in this model Saturn or a similar model?

    Sorry if all of this has been answered already, I've search several boards and googled it to try and do the research myself, but can't seem to find a whole lot of info on doing this stuff to the newer years.

    it will throw transmission error codes, but it should still run the same
    as for the MS ive never done it, but it looks pretty easy
