Anyone mess with the low throttle fuel settings?
The general consensus is just to leave these alone, but I think some more drivability can be eaked out with changing the 40%-70% throttle fuel settings. Anyone have any input?

Actually no I haven't. Left it at 0 across the board -- the low end is already pretty lean from the factory.

I have played with mine and it take sometime to get them decent. I have my LTFT right around 1-2 at pretty much every RMP setting.

it's complicated, because once you change that you have to accomodate the high throttle fuel setting.

some sorta math you have to do for compensation....

what about when you add 660-720 injectors. can the ecu still give drivability at low rpms?

With larger injectors you should change the settings some.

Do you have a way to view your STFT and LTFT? If not, you will have no idea where you are at.
