Don't bump old posts for a question that has been answered many times. Also, if you need to, make a new thread. The reason I say this is because many of thses guys aren't active on Nico anymore.

**** May Be Worthy Of Being STICKY'd ****

Hey everyone whats up.

Well as I saw another thread asking for SAFC help (as did I) and I thought it might be a good idea to make a thread where it would be WAY easier to search out answers, see people's systems and settings.

These units can be complicated at first and even appear a little ominous to the first timer so this should help.

So for those who are already using either the SAFC (LCD screen with button's) or the SAFC II (LCD screen with knob) post up your COMPLETE settings including, Throttle Point, NE Points, High/Low Throttle and Fuel % Correction for each NE Point.

Also include what turbo system your running like kind of turbo, injector's, ect, ect. Don't forget to mention if you've tunned on the dyno, via a Wideband or not at all.

True no two cars will be running the exact same settings despite maybe having the same turbo system but at least it will give new people something to research on and use to just drive there cars and get to the dyno or tune with a wideband.

Anyway here's my SAFC settings (have NOT hit the dyno as yet)

NE Points: 1000rpm, 2500rpm, 3000rpm, 3500rpm, 4000rpm, 4500rpm, 5000rpm and 6000rpm

Throttle Point: Lo - 10% / High - 43%

Low Throttle Fuel Correction: -25% across ALL NE Points

High Throttle Fuel Correction: 1000rpm -17%, 2500rpm -17%, 3000 -16%, 3500rpm -15%, 4000rpm -15%, 4500rpm -15%, 5000rpm -15% and 6000rpm -15%

My turbo system is, SSAutochrome Manifold, SR T25 Turbo, SR Turbo Extension, Megan Racing 3" Downpipe, SR 370cc Injector's, Megan Racing Fuel Pressure Regulator, 300zx Fuel Filter, SR SMIC, Walboro Fuel Pump, GReddy Type S BOV (atmospheric) and the SAFC (buttons)

So that's me how about you???

Also PLEASE feel free to ask any questions, post any comments or concerns as this will probabley go a long to helping out a lot of people.

Take care guys.

need lil help SIDEWAYZ...what setting should i change if im running ur setup but my boost spikes to 12psi...what should i use for the HI THROTTLE settings??

Re: SAFC Settings, Question, Comments and Concerns Thread (Biggamehit)

nlzmo400r — 2007-10-16T12:19:31-08:00

So yes, i have searched but am not seeing what im looking for. Any help is greatly appreciated guys, i know there are plenty of Gurus in these forums and are very kind to us n00bs who are only trying to learn...thanks in advanced!

My Set Up:
KA24DE-T
T25
3inch DP/no exhaust yet
FMIC
SR intake/Stock S13 MAF
370cc SR injectors
SAFC2
AEM Wideband(getting bung welded today for better results)
1st Gen/EVO BOV w/ recirculation Tube(rigged, not working well)

-I have shortly tuned with a wideband but we had the sensor rigged in the back of the downpipe, i am now going to get a bung welded onto my downpipe for correct results.
-I am also looking to replace the stock SR intake b/c it's that rubber **** and it's hard to clamp hose clamps on rubber, so im going to pick up an alluminum one.
Questions:
1. On the SAFC2, where it says(under the THR settiings i believe):
Neo1: 800rpm
Neo2: 1000rpm...etc. How can i adjust these, it only lets me highlight them and not change them in anyway?
2. When Monitoring AFL, what exactly does it stand for and mean;Airflow? Is there any "norm" at idle that it should be?
3. Dec. Air, does it only account your settings if you're running open BOV(Un-recirculated) b/c it doesn't seem to be helping my hold idle when clutched in or in neutral. I am forced to heel toe until slowly 0% throttle then i can let off the gas, and even then the idle is at 450rpm..then only once i completely stop will the rpm rise back to 750ish...
4. For my MAF "IN" and "OUT" should it be 1 and 1, or 5 and 5?
5. Also, I'm not sure under which settings it's under but where it asks you:
Low THR xx% and HI THR xxx%, for mine i have it at Low 10% HIgh 50%, should this be at anything else, also does this mean that for the settings i have changed for my low THR they only apply when i am in between 10%-49% throttle and the same applies for the high throttle?
6. Air bung on the valve cover, is it necessary to have a hose going from this to the intake right before the Filter? I have one of those small filters on it and plugged the spot on the intake since it's after the MAF...?

I think that's all i can think of for now, again guys, any help is greatly appreciated; just trying to learn from people in the know. Thanks.

-Chris

bring this back to life....im just getting to that part in my setup, Sidewayz...my intercooler piping pics are on the link in my signature...but ill be wiring my SAFC asap and need some pretty accurate and safe settings for

setup in signature too...I was goin by Sidewayz setup cuz exactly the same except he lives in colder wheather than my Texas heat...so should there be any changes in any of ther stated numbers??? i have all 3 settings Sidewayz posted but first seemed to be set for normal temps instead of cooler air but let me know...cmon guys, know theres alot of KAT out there with this setup....need lil help on the wiring--the white and yellow for air pressure, white goes to ecu pin #16, but this pic shows yellow comin from another white wire but not sure what ecu pin #...any help?? Thanks everyone and lets keep this alive.

My current setup are Greddy FMIC, T28,255lph pump, 555cc injectors, and a AEM wideband + hks blowoff--. close to what WHEELWONDER have..
I forgot what my previous settings where but this is my current

I know this is REALLY old, but in this situation, your MAF wire had to be wired backwards.

red240ne — 2007-06-25T22:27:50-08:00

I run 2 in 5 out for the MAF setting, but I have an s13. But basically for the MAF setting you can just play with it until your idle smooths out.

Anyone have settings to use with a JWT ecu? I have 740 injectors with cobra maf and JWT ecu. Car runs very rich and would like to fine tune it. AFC is already installed (well will b today) but just turned off because I dont know how to set it.

Re: (kas14slider)

1995240sxSE — 2007-06-06T12:00:40-08:00

why is your timing retarted? A birth defect? Sorry I just woke up. How much boost are you running? Not too sure you need to adjust timing unless u are running a bunch of boost. your right on safc hotwire 2in 2out for stock maf. also 4 cyl with arrow from bottom left pointing to top right! Just put all your high maps at 0% and your low at -23%. that should keep ya very rich and safe! Dont boost too much till ya get a wideband or a dyno tune!

kas14slider — 2007-06-05T00:09:12-08:00

Could anyone help me with these settings, I don't have any money to afford a tune right now. Car is a 96 s14 with stock maf

Also what should be the correct sensor type, I have it as hot wire and set at 2 in 2 out but I think this is wrong

My setup is:
-s14 t28 at stock boost
-Ebay Godspeed FMIC
-Taurus e-fan
-Megan 2.5" catback
-ebay manifold and downpipe
-Walbro 255 pump
-SAFC II
-SR 370cc's
-stock s14 MAF
-retarded timing

Your both very welcome. I don't know how much it helped out but, anything is better then nothing.

Tx-Sx-FS - FOR SURE let me know about that fmic kit, take pic's of the install, pic's of any prob's, how you solved them and so on. It's a great deal on that kit and I may be interested in it myself. Just want to know about it all first.

Hopefully other people will be posting up there settings and system so everyone will have lots of information to assist in there own set up.

Just wanted to say you have a BEAUTIFUL car dude. That blue is amazing. And I hate blue cars honestly, but yours is just, wow. crazy.

In response to the AFC settings, I need to play with mine a bit more, its really fun to see the drastic changes in power you make with the AFC, + or - of course. I got mine from idling like turds (black smoke everywhere) to idling like a top. My dec air settings never seemed to affect idle at all. My MAF output voltage is the main one I needed to use. I'm at 1 in 1 out with a N60 maxima MAF. I'm running a very similar setup

XO2 Manifold
T25
370cc
N60 MAF
3 inch downpipe
3 inch test pipe
Apexi N1 dual exhaust
Apexi BOV
FMIC
SAFC 2
Manual boost controller

My car kept popping couplers at 10psi so I bought T bolt clamps and they're hopefully on their way. Once I get those installed I can fine tune the boost controller(getting boost creep a lot) as well as the SAFC settings.

I have 460cc injectores. Try low at -40 accross the board and high turn to -27 across the board, but don't get into boost. If it smells like your running rich just turn it down some more. I have to run -50 at idle and then it goes up from there , but my hi throttle starts at -10 and goes all the way to +50

**** NOOB QUESTION ALERT ****

Is an SAFCII and a wideband an alternative to a tuned ECU like enthalpy?

I was planning on getting an enthalpy, but because I plan on many stages it will get very expensive very quickly.

Re: (Mustangs_Suck)

side waz — 2005-11-28T20:45:42-08:00

DUDE, you really got lucky! I'm very suprised your still driving. LOL

Well I had to adjust my settings again on the Decl.

THR% - 5.0%
NE1 - 1.9
NE2 - 3.5

As well my idle was rough so adjusted that back to around 900 rpms (ish) from the srcew on the motor. Now it jumps a little but I tracked that down to my bov being to lose. However untill I get my turbo I don't want to tighten properly as my current turbo is not making 7psi anymore. So to keep it alive on "life support" I am making sure there's almost NO compressor surge.

Seems to be working out ok and I can live with the idle problems untill I install the T28.

I will also change my Hi Throttle to 0 at my first NE Point and increase by 1% to NE Point #8. That should cover me just fine untill I hit the dyno.

well i trust your word, thx for clearing that up with me.

I guess I got lucky, as I drove it for a few hundred miles, and wailed on it a few times, with that 14.5:1 setting.

Even on NA, max power is still made around 12.8:1 with proper timing to accompany it.

And do you guys having problems have widebands??? If you have a wideband, then tuning the SAFC should take 10 minutes max...

lol, a little bit longer. gotta mess with timing too.

So not all +%'s are wrong...depends on your car I guess...but idk..I feel as if they didn't tune it well..they said my car was running a dangerous "14.5:1 AFR" and they set it down to a 12.5:1, but from what I've read on here, or from what I recall at least, 14.5:1 is more of an optiumum number than what they set it down to.

Hey man.

I never needed the Dec function either till I changed my bov around a little. As long as your having little to no compressor surge, don't worry about it. "If it ain't broke, don't fix it" LOL.

As for you settings, it's my understanding that the 0 is the normal flow rate for injector's. So going in to - will lessen the amount of fuel and + will increase the amount.

I do know that once you reach the injector's max on the duty cycle, it will lean out despite the fact you think your adding fuel.

I'm not sure how much that helps and I know there's someone here who can answer it better.

Maybe PM structure240 b/c I've read that he's the SAFC wiz on here.

Re: (side waz)

deathBooster — 2005-11-23T15:26:05-08:00

There is a big confusion in my head right now.

My current settings are : t28 turbo, 555cc injector, stock sr maf, 3" downpipe + straight cat.

I didnt not set the DECEL SETTINGs becoz it seems fine to me. is in factory default..

and my
Throttle point is: Lo 44%, Hi 45%
NE POINTS: 1000, 1600, 2200, 3400, 4000, 5000, 6000, 7000
LO : 25%, 25%, 25% , 26% , 26% , 27% , 27%, 28%
HI : 31%, 31%, 31% , 32% , 32% , 33% , 33%, 33%

everything runs fin my A/F readings are 14-14.7 when cruising but chokes when boosting.

now my big confusion.. when I was setting the LO 1000rpm... I move it down toward the negative side say -10% my wideband will read very RICH.. (+11 and higher) ??? why?? i though negative readings is to make it lean and possitive readings to make it richer??

am I getting it wrong??

Re: (side waz)

side waz — 2005-11-23T13:03:24-08:00

Ok I think I got it. First though I did this on a cold start, wrote down the correct info and imputed it. Then, using the adjustment screw on the motor, turned my idle down from 950rpm ish, to around 800. Everything seemed fine and I also did some bov work, losening it, and went for a boot.

As it turned out I stalled when letting off the throttle. Then it hit me b/c it's very cold up here now, and I had the heater and rear defrost on, I did'nt take that in to account as it takes more power and lowers the rpm's even at idle. So back under the hood I went. Keeping the heat on high and the rear defrost on I adjusted the idle back up to around 900rpm's, played with the Dec settings and I "THINK" it's working. I'll know tomorrow after the car sat all night.

Anyway my new set up, including the DEC SETTINGS are,

NE POINTS: 1000rpm, 2000rpm, 3000rpm, 3500rpm, 4000rpm, 4500rpm, 5000rpm and 6000rpm

THROTTLE POINT'S: Lo - 10%, Hi - 40%

FUEL CORRECTION FOR NE POINTS:
LO gt; From 1000rpm's to 5000rpm's -27%, 6000rpm's -26%
HI gt; -15%, -13%, -10%, -8%, -5%, -4%, -3%, -2%

DECEL SETTINGS:
THR% - 4.5%
NE1 - 0.4
NE2 - 3.5

Can someone let me know if I'm bang on or at least close to having eh Dec Settings right?

Thanks a lot.

sorry fiz, just trying to help here

""when the car is completely cool start it up. have the safc mointoring throttle %, air flow, and rpms. have the engine at 1000rpms and write down the air flow. then have the engine at 2000rpms and write down the throttle % and air flow.

now go to the dec. air settings. the THR setting is the throttle % you documented at 2000rpms. the NE1 setting is the air flow you had at 1000rpms. the NE2 setting is the air flow you had at 2000rpms. this will get you very close to the settings you need. may not be perfect but very close. this will allow you to run an atmospheric bov without stumbling between gears""

Reviving this thread with a question to this.

How close is close? I'm asking b/c I am going have to use this function on my SAFC and there's been a couple of guys here who have really helped with this but it's sort of two different ways of doing it.

Whats the best, most accurate way? There is what you suggested, then there is this,

taken from S14tat:
this is what you do in laymens term.

the ne1 and ne2 is the air flow percent you put down.

ne1 would be the first point on your lo- hi throttle map rpm.

ne2 would be the second point on your lo-hi throttle map rpm.

the throttle number on the decel air would be throttle percent its required to rev it to the ne2 rpm.

and then your done. It just gets a little confusing having a bunch of different ways to something thats probabley really simple. LOL

I though 0% reading on the S-AFC is the normal reading for you stock ECU isnt it?? Right now i am using 555cc injectors shouldnt i make the Lo Throttle richer??

Re: (deathBooster)

side waz — 2005-11-09T18:44:05-08:00

Well I'm no expert but the closer to the 0 mark you get, the closer you get to the normal flow rate of the injector's. Anything above 0 would be richer and below would be leaner. So I'm pretty sure you have it right.

At least that's my understanding but anyone please correct me if I'm wrong.

Re: (side waz)

Thanks a lot guys..

by the way side waz.. i need to make sure in the hi and low throttle.. when i move toward -50% or +50%... to the negative side is leaner.. and to the positive richer?? right??

right now my settings seems to be alright.

Here is a link that might help somebody understand the afc..

side waz — 2005-11-09T06:44:12-08:00

Hey guys.

Ok here's the new numbers I'm using and so far they seem to be working out ok as according to my air/fuel gauge, I am staying more in the optimum range as opposed to mostly always leaning out. I know this is'nt the way to really know what my a/f's are but things do seem smoother.

I also based these on when my boost seems to really start kicking in which is approximately 3000 RPM's.

NE Points: 1000rpm, 2500, 3000, 3500, 4000, 4500, 5000, 5500

Throttle Position: Lo 15%, HI 35%

Low Throttle: -25%, -25%, -24%, -24%, -23%, -22%, -20%, -19%

HI Throttle: -15%, -13%, -11%, -8%, -6%, -5%, -4%, -2%

Since I have not yet dynoed I don't where the turbo stops making power. I lean out to much for my liking so I have'nt bothered to find that out. I do know in the higher rpm's more air is coming in and as such, more fuel needs to be added so that's why the numbers approach 0 in the high end of the power band. I don't push it all that hard either but just to a little safer if I'm playing around, it's better to be running a little rich then to lean.

Keep posting up your settings as well as anything else to do with the SAFC so people can look here for help.

Have a good one.

Most peoples settings are usually negative numbers like mine posted above. 15-16 afrs are deadly, try using negative numbers for your high throttle map. It almost sounds like you SafcII is miswired.

Today i did the cold start thing to fix the dec air on my afc.. and it doesnt work..
i set the throtle to 1%, and ne1 to 4, and ne2 to 5, then i start the car and start turning the ne1 toward 0 and nothing happens... car keep running fine..car will not sputter or get rough..
then when driving it.. if i slam on the gas and boost +10psi the car will run lean 15-16... and you here the misfire.. how ever if i accelerate slowly toward 6-7krpm it wont go lean it will stay between 11-13.. how do i fix this?? sometimes at iddle i am running rich..

Just fig out now that with the current settings
Hi Throttle: +25% 1000-2200, +30% 2800, +35 3400-7600
Lo throttle: +25% 1000-7600
Throttle: lo 10%, hi 35%
dec air: ****% ne1 10% , ne2 10% --gt; need to fix this tomorow with cold start

result:
4000rmp -gt; 10psi the car will go lean 14.7-15... afl=0.5...

how do i make it rich??
do i change the hi throttle 3400-7600 to +45%
what are the correct readings for the afl????

Hey guys.

Well finally there's some settings being posted up so that's good.

Now I've seen a lot of you mentioning the Dec Air feature on the SAFC. I totally understand it's function as it aids in not letting the car stall out after letting off the throttle when it's wide open.

I am currently not using though, as I adjusted my idle on the motor from 7-750ish to 9-950 ish and so far the car has'nt stalled out on me once. I'm just curious though if the Dec Air function MUST be used b/c it's connected to the rest of the SAFC in some way or, does it not matter about using it and the fact that I've solved any stall issues via motor is fine? A little clerification here would be great.

I've also changed some of my current settings a little and will post them up tomorrow. I am not sure how well it's really working but I think there's a difference. According to my air/fuel gauge ( which I know is'nt all that accurate at all) I don't lean out quite as fast and it feels a little smoother.

I just wish I could hit the dyno sometime soon as I'd like to see how close I am, either that or see someone's settings here that has been dynoed and uses the same set up as me.

My most recent settings:

Hi Throttle: +25% 1000-2200, +30% 2800, +40 3400-7600
Lo throttle: +23% 1000-7600
Throttle: lo 10%, hi 35%
dec air: 1.1% ne1 1.4% , ne2 2.4% --gt; need to fix this tomorow with cold start

a/f readings from my AEM widebad
idle at 828rpm afl = 3.7%-4% a/f unstable mostly between 12-14 maybe 13

2000rpm when cruising afl = 2.5%

3000rpm afl = 1.3%

So, this is wat i collected just now.. how bad is this??

WDRacing — 2005-10-27T14:40:32-08:00

With 555cc injectors you'll want to pull more like -50 until you start hitting boost. So I'd use 800rpm as a start then, add fuel at whatever rpm you start to see boost.

It's very hard to bench tune a car. What are your actual AFR's? What rpm do you see boost? Are you using a wideband air fuel monitor, cause the other ones simply don't work. You'll know your rich, but thats about it, you don't wanna tune on boost with one. They are only marginal for idle.

Your decel air settings also have a HUGE part to play with idle. But EVERY car is different with those, although we can probably get you close. Email Structure if you have problems, he's a wiz with SAFII. I can tune almost anything, but I hate doing it over the internet. If something were to go wrong, I'd feel pretty badly.

1WheelWonder — 2005-10-27T13:48:33-08:00

What are your hi/lo settings for the rest of the board, how are your afr readings while crusing, and what do they sit at during idle? Mine bounce a little but never more than a point either way.

So what is Anthony's way? i'm trying to get as many tuning tips before i start my own project.

fiznat — 2005-10-25T14:03:52-08:00

Hey how about less talk about when we're gonna sticky the thread, and more SAFC settings! haha, thats the reason the thread would be worthy of getting stickied, right? ...Cause it would be full of lots of useful info? So far we only have 2 people who posted their settings!

1WheelWonder — 2005-10-25T13:39:12-08:00

Yes I did use Anthonys way, works like a charm.

Re: (1WheelWonder)

Craving4Boost — 2005-10-25T13:16:17-08:00

wheelwonder - did you use anthonys way of setting the dec. air settings or another? just wondering

No need to sticky it.

I say one of the mods should add it to the "great info here" thread that's already stickied. It just makes this forum much less cluttered.

Anyway, I will post my settings after I tune some more.

That way works out great to but untill we get a lot more reply's with peoples settings and what not, I think having it "Sticky'd" would be best.

Then after theres a lot of info, toss in the section.

Keeping this thread right up top and easy to see will hopefully get more guys adding there info, questions, comments or concerns on the SAFC.

crzycav86 - I look forward to seeing your settings man.

Have a good one guys.

ok, i agree with ^^^ instead. Makes things really easy instead a cluttered.

With my setup I am using a t28 .60a/r comp and .86a/r turbine, 255lph pump, 555cc injectors. Afr's are constantly watched with a plx m-300 wideband.

Lo map is -50% across the board, which gives me 14.5-15.5 afr's while cruising around town.

High map is -50% from 1000-2200rpm's, -45% at 2800rpm's and -35% 3400-7000rpm's which gives me afr's of 12.5 during spool and 10.8 to 11.5 during full boost, which is at about 10.5psi.

NE points are 1000,1600,2200,2800,3400,4000,4600,5200,5800,6400,7000, and 7600rpms

Dec settings are 1.1,1.4, and 2.0. I have no stalling problems at all.

Throttle point is 10% and 33%

All These settings are working really good for me, I have excellent streetability and it pulls like hell at WOT. However, i'm not to certain about the NE points, I have not touched them.

This is a good idea -- can anyone else contribute? Complete tunes are realy what we're looking for: meaning running, dynoned, finished and working setups.

Hey thanks, I'm glad you agree.

Do you think you could make this thread a "Sticky" then? It's always up top and easily accessable.

I also agree that FULLY tunned settings are the best but at least having numbers (like mine even) allows the guys a base starting to point. You can't push to hard or really stay in the boost for to long, as you'll lean out over 4500rpm's, but untill they hit the dyno or get a wideband you can drive with no issues.

Come guys post up.

Your both very welcome. I don't know how much it helped out but, anything is better then nothing.

Hopefully other people will be posting up there settings and system so everyone will have lots of information to assist in there own set up.

Re: Your Turbo System & SAFC Settings (side waz)

Tx-Sx-FS — 2005-10-24T11:24:55-08:00

he has the exact setup that I do, Ill be testing the settings when the engine goes in sometime this or next week. Thanks Sidewaz.

And my FMIC was ordered last week, but just got shipped today, so another week or two for that to come in. D@MN them

z3ro069 — 2005-10-23T21:02:23-08:00

SWEET!! man I am gonna be running the same setup without the greddy bov.. anyway i'm just finishing up here within the next week hopefully. And I am glad that you posted this for me to experiment. thanks alot man ! i'll keep in touch. Oh and I think ppl who post their settings and whatnot will at least help ppl get in the ball park.
