I have 440cc injectors in my b16a motor with 4:1 fmu and walbro intank pump and am currently running the afc hack. How many degrees do i set my btm to? My ignition timing is stock and when i hit 12psi, it hesitates alot, even with the btm set to 0, seems like i'm getting too much fuel. Do i need to take the fmu off? or should i advance my timing a little? Thanks.
