    I feel like B2404 is where i need to be, but the units justs says milligrams. I'm not sure if thats measuring an offset of some other airflow or what. I'm certain airflow doesn't get that low on decel.

    The description says "airflow" which implies "g/s" and the values in B2404 fit these units (e.g. 120 g/s is plausible);

    "airmass" would imply "g/cyl" or "mg/cyl" and the values in B2404 do not fit those units (e.g. 120 g/cyl or 0.120 g/cyl don't fit... should be more like 0.60 g/cyl or 600 mg/cyl).



    Try lowering the values in B2404.

    Tried reducing by 20%. Not enabling DFCO yet. Going to experiment a little.

    My guess is that B2404 is cylinder charge... milligrams/cylinder.

    Try increasing all the values in B2404 by 25% from the values you had in the tune you posted. Also, try doubling all the values in B2403.

    Makes sense that milligrams is cylinder charge. And that worked.
