Initial settings for S-AFC - everyone's opinion

[dj_lethrow]

I have a walbro 255HP fuel pump, FIC 650cc injectors, soon to come aeromotive fuel pressure regulator and S-AFC2. It has the stock 14b turbo. I am at my very begining with tuning and could use some base settings to go with. If anyone knows of some good start settings I could use I would appreciate the help. Feel free to email me at dj_lethrow@hotmail.com.

This thread would be a lot more helpful if people just posted their settings and that's it. No pointless posts or people asking if anyone has their setup and if they could post their settings ... if they wanted to post them they would have already done it. Someone please clean up this thread and only leave useful posts .. not posts of people asking what their settings should be. :thumbdown

There aren't any. Anything useful is in the FAQs or on your loggers.

Leave them zeroed out ... you have no need to make any adjustments really.

[olmytsi]

ummm. The car was backfiring so it was runnin really rich so i backed it out til it no longer backfires so its not as rich but i guess ill wait til i get a pocketlogger but leaving it at zero is DEFINITALY not the right setign for my setup

I assume you have a regulator to control that fuel?

[1fast97gsx]

why do you have a pump that big on stock injectors? I guess give -5 across a try, but chances are you are going to run into problems with that stock fpr overrunning with that pump.

Depending on if you hooked the second input wire on the safc into your O2 sensor 1 you can go to sensor check and just floor your car and read the middle numbers. Keep adjusting the safc till it says roughly .92 v. Keep in mind this is not the way to do this, but generally you should have a logger first and then upgrade fuel stuff. Your low settings you'll have to do by feel and sound for now but redo them as soon as the logger comes.

i dont have a fuel pressure regulator because i cant afford one right now but its next. I have a 255 because i bought it off a friend for like 30 bux only 2 months old.

[Pizzy]

BTW, having the correct fuel pressure is imperative to making correct tuning decisions. I just realized that my afpr was set to 33psi, not 43 like the stock setting. It's no wonder my safc values were so far off from everyone else's. "Why does it still want more fuel!?"

My modifications are: FP 17PSI actuator, Manual boost controller, Injen intake, Greddy Upper intercooler pipe and type S BOV, Ported EVO III O2 sensor housing and exhaust manifold, Apex'I GT downpipe and catback, AEM AFPR with B&M gauge, Walbro 255 lph HP fuel pump, FIC 550cc injectors, Aeromotive 10 micro Fuel filter,

These are the S-AFC settings:

Can someone give me a base setting for my safc2

im scared to put it on my car with out setting and im having a hard time learning this stuff

I have my honeycombs remvoed- s16g ported-web cams-255 fp-2.5 down pipe-3 inch ex-stock injectors-underdrive pully-front mount intercoller-hks ssbov-few other small thing
can anybody help me ###

[kyle h.]

-3" intake 2g mas (1g car), one side honeycomb removed (previous owner of the mas)
-2.5" exhaust o2 housing back, no cat.
-boost: 10psi creaping fast to 19psi
-stock 450cc injectors, stock fuel pressure, stock pump (rewired)
-stock pipes, stock side mount with duct tape covering pin holes
-leaky tb shaft seal, and no other boost/vac leaks
-stock turbo (14b) and manifold (1g) unported.

low thr: +18% @ 1000rpm, +17% @ 1800 rpm, and then a faster decrease to +6% around 3000rpm.

high thr: +7% up to 3000rpm, +13% @ 4000 and so on, ending with 18% @ 7000rpm.

max d/c i've seen with this setup was 106%

3rd & 4th gear pulls on a cool even i was at 93% at the last WOT rpms.

i get awesome timing, obviously if the knock is low. don't reccomend boosting much during the hot day traffic.
