Everyones N/A dynoed S-AFC settings wanted
Ok. I know everyone would say every 7 is difference and I need to get my own settings but I want to know your S-AFC settings for N/A cars only and ones with lots of mods. Yes Bambam if your still alive , even your settings. Im going to get a general idea of were I can set my car at. I have MZSP7 mods except for short fb Tranny. This is NOT my daily driver 7 so Im looking for some easy hp without dyno tuning. Now I have seen N/As run more than -13% fuel reduction across the board on stock fuel system.
Thnx alot
Thnx alot

you have to be carefull across series too. the ECU's react way different to mods. the 86-88 lean out and the 89-91 richen up with mods. so don't either bother looking at poeples #'s with a different series.

PD-DAY ! thnx alot that helps. Although I would like the low settings as well. I have a 89GXL series 5 so it does run really rich believe me. I see 14% at the most but I have lots more mods so I will probly do a tad more each RPM. Also whats your low settings? Thnx a billion especialy for the AF% because I wanted to compare that to my Ported manifolds. I will get back with my results during this weekend.
Anyone else?

PP13bnos? Thnx alot. Your profile doesent mention wich car its for. Don you have a S4 N/A with a mild street port? I think I would be able to use your settings but backed off around 6 points because I dont have a street port. Plus I have much greater A/F ratio to begin with because its a S5 car and the fuel burns my eyes.
Also PP13Bnos? whats your A/F% readings? and 40%low 80% high?
Silver Rotor? I will try and keep this thread alive until I post my findings as well so please type back when you get some. thnx everyone

I had a 10-1 a/f ration without the s-afc. Use at your own risk. CJ

If i drive freeway with a less than a half a dozen first through 3rd gear 8.5k rpms runs, I usually get around 27mpg. I think that if i left my foot out of it for the entire tank of fuel, drove nothing but freeway, and shifted before 4k....I bet i could get 30mpg. CJ

Thats F-in awsome. I dont think I will be going that low , although Good to know my engine can handle it.
PPNOS or anyone? How do I know when Im at 14-1 a/f ratio without a dyno? If I hook up the blue wire to oxygen sensor what % readings should I see for that A/F ratio ?

Ok I installed my S-AFC but didnt tune it. I saw a 50.7% A/F ratio. I hope to gain 10points by tuning but I dont know. That would put me up to PPnos and he has a street port. We will see.
Also My sensor readings are In-1 3.8v in-2 .02v In-3 8.9v
Can somone tell me if these are to spec? thnx

Excuse me. I meant 3.9 for TPS and like .02 or something for oxy wich isnt conected. It fluctuates a little. Actually all of them do. Are these readings ok?

Also im thinking that the A/F % is not directly related to how much power your car makes. You can have more % air flow but make less power than a car the other way around.
