This is strictly a curiosity question.

I've read a lot and picked up that if LTFT's are positive at WOT, then the computer uses another variable for adding fuel.
Does anyone know what variable/table is used by the computer for this?
Is it accessible by LS1Edit, TechII, or HP Tuners?

Or is it just the computer biasing x% richer for the x% the LTFT is positive?
