I would add them and try to utilize them. The advantage as I see it is, there is now way for the PCM to make fuel adgustments in open loop, but it will in closed loop. When you go WOT the pcm sets the STFT to 0 but it does add the LTFT to the WOT run. This adjustment is to correct fueling do to altitude and barometric pressure. I guess you could say, when the engine is correcting STFT it is learning the conditions of the moment and it applies this at WOT. In open loop only, it does not make the minor fuel adjustments and therefor the pcm will not make LTFT corrections. In this situation you would always have to use your tuning software and WB to make the minor adjustments caused from alltutude and barometric pressure changes.

If for no other reason, I would put them in just to correct the innacurate fueling that can be caused in heavy traffic due to IAT sensor heatsoak.

bingo!! I would have mine in closed loop at sub 2000rpms if i didnt run c16 at the track. (would kill the sensors pretty quickly)

gametech: using efilive cos...do you know if iat/fueling correction table affects WOT as well? I guess I should just try it...mine goes lean at idle-p/t with heatsoaked IAT sensor.

I have no idea. I'm using HPT.

Yeah A00014 table will work at any point.
IMO CLSD is very good. Dont run LTFT, just run STFT's
