    What year?

    I have a dynojet cmd fuel controler for sale. With auto tune. They work pretty good.

    You install the cmd on the ski. Then use a laptop to input what afr you want it to run. Then go out and ride it and it auto tunes itself.

    There is a little more to it than than but thats the basics on how it works.
    It also runs a wideband sensor so it can read afr and then make adjustments.

    The cmd is fairly new technology so lots of people still run what they know.

    Its personal preference.
