I borrowed a AF meter from a friend and was wondering what is the best process for reading and setting the mixture.
Can I take readings at idle and hold the throttle at 3k and take another reading or do i need to drive it with it under load? based on readings which adjustment do I move first static or dynamic? |

Got this from one of Chris Foley's posts
in A:F ratio, you want to see: 13.5-12.9 on the gauge while accelerating or climbing, 12.8-12.5 at WOT, and 16-17 while cruising, going downhill or decelerating. Right now I am in those ranges with FI. A little richer on WOT as I can get to 11.5 at times. But seems to run well in these ranges. |

I am getting 27-28 range. Acceleration and WOT I am close but the idle numbers seem way too lean. |
