Ok I have a 2010 nytro mtx 162 with a stage 1 supercharger. I am running at 500 feet above sea level with about 7 psi of boost and 97 octane gas. In my green mode i have a good 12.5 AFR. When it turns to yellow it jumps up to 14.5-15 AFR and red is 12.5 AFR and WOT is 11.5-12. I have turned the yellow up all the way and messed with the boost fuel adder and fuel pump accelerator and altitude comp. what ever i do other than pinning it to get past the yellow i can not get my AFR down in yellow mode. I know I am almost ridding at sea level so 14.5 is supose to be the ideal AFR. I would like to get it down to the mid 12s like the other two. I figure that gas is cheaper than a motor. Please help my figure out how to get my yellow mode AFR down.

If I am not mistaken the colour of lights when running may not be the same as the colours when programming the fuel curve.
That should also be in the instructions.
I would add lots of fuel and then start to reduce it when it is overfueling.
I have a apex so the numbers will be different I would use some higher octane fuel until you have it perfect. I use straight Av gas at 10-11 psi
