    Ebay M42 chips

    Anyone in the USA try one? Says disables O2. They are inexpensive.

    The one claiming +12hp and with a 7,200rpm rev limit? I haven't used it but that's crap. There's no way you're going to get 12hp out of a chip tune on an M42 and revving it to 7,200rpm is pointless, it's out of breath by 6,500rpm with stock cams and intake. Have a look at the results with MarkD's chip: http://www.m42club.com/forum/index.php?topic=11635.0

      I'm running one and asked sssquid to check the chip for that. The one I had does not disable o2 feedback and helps the engine a fair bit. With that said i'm runnig a sssquid chip now.

      No one makes this car anymore. The government won't allow them, normal people won't buy them. So it's up to us: the freaks, the weirdos, the informed. To buy them, to appreciate them, and most importantly, to drive them.

        Agree, chips will not provide 12HP, even at the flywheel. A real tune for your engine may get you there.

        Revving to or above stock redline is very helpful on track, and it's just plain fun if the valvetrain is healthy.

            +1 for Sssquid

            I have been working with him on a custom tune for my 2.1L M42 and he takes his tunes seriously.
