    If we're talking pie in the sky, is it possible to kill Hill Assist for the Sport crowd?

    I believe I is a function in the ABS unit?

    As someone pushing the upper limits of “healthy weight” on the BMI chart, I find this offensive. Girls can be fat too.

    Hey folks, can you guys confirm, is DFCO only an issue in 1rst gear? or all gears?

    Mainly 1st gear here. Coasting in stop-n-go traffic and offroad.

    Sorry!

    I find it feels active when coasting to a stop in 6th as well.

    Yup exactly. You can coast down and once you go far enough it lets go

    Okay well testing so far concludes that from gear 2-6 we can get fuel to stay cut until 650 rpm.
    working on 1rst gear.

    The Port injection, Direct Injection, Split injection code is what sent me down this code rabbit hole.

    So, with DFCO there are a few components,
    2-6th gear is controlled separate than 1rst gear

    There is also an additional injection amount added on initial refueling.

    the code will take me a little longer to sort through.
    The flow chart for it.
    mind boggling.

    also found the code to change the target AFR to whatever we want.. make it run leaner..richer all the time, etc. Make it leaner or richer depending on temp..

    That's a whole lot nicer word than what I was thinking. How the hell does this engine even run with decision trees like that.
