I have a Power Commander III that I map using the data output from a Twin Scan+. Should I be trying for a 13.2 A/F ratio in every cell, or are there ranges that should be richer or leaner than that?
Our Friends at DynoJet had this to say:
If you are looking for the best overall performance then you should try to achieve a fuel ratio of around 12.8-13.4:1. If fuel mileage is a concern then you may want to shoot for 13.8:1 in the cruise range.
