Just finished my AFC hack, D16Z6, S-AFC, 440cc, 255lph in tank, no missing link, FMIC, standard fuel pressure regulator

problem i have is that i have to have the AFC set at -30% throughout cos if i try going -40% i can hear detonation, My AF ratio reads rich but surely something is wrong cos i see you guys all run a setting of around -40% and i can only go -30%!!! Im only running 6psi!!!

Whats going on??? is it because my timing is set at the factory setting?? should i retard it??

I am correct in saying you guys all run settings of around -40 arent i???

please help i wanna be running about 9psi.

deacs

 

anyone??

 

surely someone can help with this?????
