Follow
Nabors75

This video will show you where you can read and adjust the minimum and maximum values of your AFR trim and AFR learn. Note: You should not need to adjust these values. If you're finding you do have to adjust these values. You either have the wrong cam setting chosen, or an issue with your engine. (vacuum leak, O2 sensor, etc)
