Zeroing Fuel Adder for TBI

[jrotten67]

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.

Yes that’s what mines seems to default to.

The most recent $42 .adx file will not accept ZERO in fuel table two like older $42 .adx files did. The most recent $42 .adx file will defaults the values for fuel table two at 5.03 when attempting to set ZERO's. I've tuned several vehicles with fuel table two at 5.03.
