I understand fuel trims pretty well but here is what I need help with.

Are LTFT's calculated separately by fuel load cell? IOW, if I drive under varying load conditions while observing LTFT in live data will the values jump around as the computer changes fuel cell location in the computer or will LTFT stay fairly steady drifting slowly as I usually see at idle?

Vehicle is a 2002 Chevy Blazer with a Vortec 4.3L V6.

Thanks,

George
