So I had a thought about DFCO and had some questions.
Until I got my wideband and program, I never knew much about DFCO and realize that in stock form it prob saved quite a bit of gas mileage when it was active. But as I modded the truck here and there I noticed that it seems to be not as precise in activating as it was before. Looking over settings and all I think I need to adjust some but not sure where to begin.
I know one thing is I dont prefer it to be active before the eng op temp reaches a certain temp. Like when its too cold. With the exhaust being more open it pops more as I see DFCO engage in cold times of the year.
Another thing is it seems on the highway to be less active when it should be. The stock rear gear ratio was 3.08 and I have 3.73 now. Since the RPMs in each gear cruising are directly affected by the gear swap, would the DFCO not be effected as well? Being a peramiter of maybe MAP entry or something need to be altered? And if so, would lowering it or raising it be the direction to go?
I am learning but is it possible to log a MAP pid with a ?? pid to compare to?

Thx for the continuing help!, Mike
