TunerPro recommends zeroing out the Fuel Adder and adding this value to my VE table while logging data. Whenever I do that and re open it, it changes from the zero I set it at to 5.08....why? Can I just leave it at 5.08 and just subtract that value from my original Fuel Adder value when I get the VE tables close? If not how do I get this table to zero and stay zero.
