Anyone know what parameters the DIC uses to calculate fuel mileage?

Since setting my LTFT's to -4, I've been getting about 1mpg better.

If I understood what I did to my Injector Fuel Rate (IFR) table for the LTFT's, I tricked the computer into thinking the injectors were smaller, so more fuel was requested from them.

I'd imagine I'd be getting slightly worse mileage... unless a clean part throttle tune helps mileage that much?

I don't know if it's that, or the computer is factoring in "smaller injectors" I'm running.

Did you try posting this in the PCM forum? I would think that everyone that scans that board would be able to help you. I would help if I could.

Yeah, I was going to but it looks like a majority of the people there are car-guys, and I didn't think they had this function.
