Let's say we are doing a VE tune. PE is disabbled, but AE is still part of the equation. I'm sure it has to be or you would probably never be able to accelerate while tuning fuel trims without the car knocking it's brains out due to lack of fuel I guess.
Now, we are VE tuning and adjusting fuel trims. Does the LTFT you see once it has settled in INCLUDE fuel supplied by the AE table? If it does, if you adjust VE to remove fuel, how do we know it was becasue the VE table was too rich and not the AE table being too rich?
