Default My MPG experiment.

So something i've noticed, i have my fuel map leaned out until about 80kpa.. <60kpa is at about 15.5-16afr (idle is at 14.5ish) Then up 80kpa is about 15 and then it richens up to 13 by 100kpa and so forth.

A lot of times i've noticed with that tunning i've had to step on it to about 80kpa to keep up with traffic off the light.

So i richened it up so it stays at 14.5afr up to 60kpa and 14 at 80kpa..the rest is normal.

Now i noticed i am rarely having to go up to 80kpa to stay with traffic on a light however now my cruise is also at 14.5afr instead of 15.5-16. For my experiment i kept it at 14.5 during acceleration then once i get to cruise i'd lean it out to 15.5... long story short i usually get 24mpg.. with this experiment i hit 26 with a simple rich during acceleration and then leaning out once i get to speed.
