mmm strange what for?... a friend a long time ago (gp 90) told me that giving 2 degrees of advance felt the most? boost but smoked even more?.... shouldn't it be the opposite? i.e. pi? advance less smoke ( of course within the limits)... then we should lower the values in the map and not to increase... you how do you do? from the tip off of each curve ( from the sixth bend) or are you working on the whole curve?
