    My bro got it and i'll and find the info.
    Hooked it up to the laptop and did the testing wed of this week.

    very simple to use.

    I think when we get our BIG motor built we're going to put a sensor on each exhaust elbow.

    usually they use them on the dyno to fine tune. however we wanted to also do it in the real world with the prop on we're running. We wanted it a little lean around 13.2-13.5 at idle so it won't load up

    What carb do you plan to use (list #)? Start with STOCK JETTING, work from there.
