I am getting ready to tune my car for the first time with my s-afc II. I would like some input on where to start at with my tuning.

1. where to set fuel pressure at
2. Baseline for the safc
3. boost level ( currently running 13-14 )

any other input is greatly appreciated

great compression, no boost leaks, doesn't burn/leak oil

1. 37psi
2. -20/-25% accross the board should be a good rich starting point.(guessing your on stock maf)
3. stay at that boost level and work your way up.


I would get a 2g maf if you dont have one yet. Also a FMIC will help a lot. You wont beable to push more than about 15psi on the stocker without causing heat soak.

do you have a wideband? i wouldnt mess with anything with the safc until you can see what your a/f ratio is.

Why is that?? He can tune to knock if he has a logger. A wideband would be great but for now he can tune to timing and knock just so he knows the motor is not getting damaged.
