Whats up everyone,

I am currently running a Apexi Neo S-AFC on my RB20DET build and I was wondering if there were any one of you out there that would share the settings on your S-AFC if you are running the same build.

Currently I am running this:

Stock RB20DET
Stock RB20 MAF
Stock Injectors
Walboro 255 fuel pump
RB25 Turbo
Stock coilpacks

I would probably be better off just playing with the settings, seeing as that everyone's car won't be tuned the same. However, I think its worth a shot to ask what setups you people are running, so I have an idea as to what to set mine up to, and not just shoot in the dark like an idiot.

Any information on this would be much appreciated. Also, I know how a lot of you feel about S-AFCs and all I can say is that IM BROKE NUKKAH!!! Cheers.

You're broke!
And I'm feeling somewhat generous!
I'll trade you a tune, for you S-AFC! You would have to cover ECU and all shipping!
Think about it, offer expires in 12hrs ;)

Cpl things,
replace the 255 with a z32 NA PUMP (191lph)
Or
Get a aftermarket FPR ( rb20 stock FPR cannot correctly regulate a 255 like a ka/sr FPR can)

With a z32 pump, Stock ecu,stock rb20 maf and rb25 turbo at 10psi, no tune just the oem base map my car runs 10.1-11.1 AFR's all day long under full throttle so no need for a tune, spend Money on a wideband instead

Keep shooting in the dark fucking with a SAFC without a wideband...you'll be broke with a broke car at the same time.

Hahahaha lolz Well now I know what my next two mods/purchases are gonna be. Thankfully I actually have a Nismo FPR that I have yet to install. Also, the car isn't my DD, so it doesn't get driven that often. Wideband coming up for sure though. Any more sage advice?

Throw away the SAFC since its the worst way to "tune" a car. Sure you can fuck around with the fuel map a bit but it doesnt do you any good when you can't tweak the timing map. You'd be better off getting an ECU rom tune.
