Buy a new Fist, return to a forum that stepped on its dick in front of you, and rock nearly every boat with one post.
Did you run each fuel type to -1 OAR (or some other standard) to allow max learning prior to logging?
Are these the latest (V400) tunes?
I am surprised OTS AF ratios are varying that much on straight 91 at mid to higher rpm. I would love to play around with datazap if you post these.
Agree still nothing like Fist. Really glad you returned.
