I mapped my entire mtf using open loop and 14.7 afr ratio with the base fuel table at 1.0. Of course projected the counts over 500ish and set the base fuel table at .75 for high load. I saw 11.0 Afr throughout my WOT pull within 5%. Barely had to tweak it. I changed before 4k to .8 in the base fuel table without changing the mtf so we will see if my afr changes when I do more testing tomorrow.

Do you all disable your knock sensors? Mine was pulling max retard at 11.0 afr, 40 degree iats, and 10 degrees max timing with them enabled. So I just shut them off under 5k for now.
