What other than Engine>Fuel>General> FA Stoich determines the part throttle AFR?
I am running 11:1 comp on a 6.1 based 426 and I need to have the part throttle AFR at ~14.4 to prevent knock during light acceleration.
I have pulled a lot of PT timing and still having this issue due to the STFT pulling fuel and keeping the AFR at 14.9-15.1 while cruising.
On WOT pulls I have the AFR set to 12.5-12.7 and there is no knock.
I have the stoich set to .0690, which should be 14.5:1
I have tried NN on and VE, same results.
Any help would be appreciated.
