SAFC 2 SR20DET settings...HELP!!!

[BlackZenki82]

okay guys, i don't want to hear anything about how crappy the SAFC is, how worthless it is, how i NEED a wide band, blah blah, i got it, it came with the car, so now i want to tweak it, or at least get it right.... oh, and i have searched and there's really not much on this, at least in depth of what i need...

so i have the SAFC,and no wide band, I'm not really seeking to tune with it, just to get a base settings that maybe someone else has...

my current fuel/air etc set up on the car is..

Stock MAFStock 370cc injectorsAPEXi super intake filter/elbowFMICWalboro 255APEXi 3" full exhaust (not sure if that matters or not)

the question is, what would/do you guys have set with similar mods... i have an issue of when i hold it over a certain RPM it gets really rich, bogs down, and smokes out the back a bit... like say i hold it at around 4500rpm it shudders.... i know what ya might be thinking "check your MAF!!" but i know it works fine so I'm sure it's something to do with the fuel curves set on the SAFC..

i could just disconnect it, but i like the feature on monitor mode that shows RPM, voltage, throttle %, and AFL % (which strangely, i think, enough, drops below 2.0% under load/mashed gas pedal)... I'd like to maintain the monitor features, without having to worry bout running lean, rich, and blowing up my investment...

as a side note, I'm completely new to "tuning" and what all the "NE", "DEC" stuff means, so take it easy on me... what I'm really hoping for it for someone to post all their settings for me to enter into mine..

so if any of you guys, in your infinite knowledge can give me a hand, it would be greatly appreciated

Its really not worth the risk to make any real changes with that AFC without monitoring whats happening to your A/F ratio, which you would need a wide band for. Since your running stock MAF and injectors I would say zero out everything if there are and changes to the fuel map on that thing just to be safe until you can afford to get a wide band, then you can make slight adjustments to either try to fix your running rich issue. If you just bought the car it might be a good idea to run some fuel system cleaner through it and see if that helps. Bottom Line: Changing your fuel map without a wideband is just a bad idea.

The NE points are just Apexi's name for making set adjustment points throughout the RPM range, you can change them to whatever you want to make adjustments exactly where you need them.

DEC may pertain to DEC AIR? which is a feature that lets you adjust the way the ECU reacts when you abruptly close the throttle or de-accelerate. Commonly used to keep the engine from stalling when you have a open atmosphere blow off valve.

Haha.

Op is going to blow his motor because he can't afford to tune it.

$5 to someone who posts a setup that leans the piss out of his motor.

I mean come on~ You can have two identical setups, but they will run/tune completely different.

Not to mention you are at a different location than someone else might be.

You don't even have any power mods. Why do you need to have a base tune!? Base tune is stock.

UGH.

Set the SAFC to 0 correction across the board and drive your car.

Don't use it as a bandaid to try and fix your engines problems.

$200 for an hour on on the dyno and tune, or 2k for a new motor/rebuild?

And don't think, "It won't happen to me". Because it will.

really all i want to do is use it as a monitor, form over function if you will... but i don't know what the guy before me has "tuned" on it, and i didn't know if it could be reset, to a default if you will, or if it had to have specific numbers for a basically stock set up..

so what i gather is just set everyhting to zero, an call it a day... i can afford a dyno tune, but it's worthless on a basically stock set up so i don't evene want to use the SAFC to "tune" with, just a another "thing" on the inside of my car...

as stated, I'm new to boost and tuning... sorry lol!!
