    Yeah , you will not like what you see , I think they had to develop a Virtual VE table just so people could understand the stupid things .
    VVT , DOD , AFM , and Flex Fuel , thanks EPA .
    Look at the Stoich setting in Fuel Management , they now start at 14.68 and go down from there to compensate for the amount of Ethanol Percentage .
    Now what is a tune again?
