Fitech - Adjusting max and min values for fuel trim and fuel learn

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)

I reset my fuel cutoff settings to your recommendations. WOW. what a difference it made. So glad I found that video. Now I won’t need to have it professionally tuned. Thanks again

Just found your video on setting decel speeds on your FiTech. You said to make settings to 16 and 18 for a manual shift car. I’m going to make that adjustment in the next couple days, I hope it works. When I remove my foot from the accelerator at speed, it doesn’t idle down very fast, and I have to brake sooner than I need to. I hope your settings work for me

I have a manual transmission car and every time I approach a stoplight and push the clutch in the car dies but will immediately crank back up when I turn the key what do I need to adjust or which video do I need to watch
