Well, ive been searching forever on starting out settings for a SAFC-II, with wiring to the ECU, and everything.. so heres what ive compiled from multiple boards, all from turbo'ed / modified KA's and KA-t's
Enjoy

===============================================
DEC AIR SETTINGS
""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""
=====================================================================
AIR FUEL RATIO HELP
14.5:1 is insanely lean on a boosted motor. You need to be around high 11's to low 12's if your under 12-15 psi. Anyone who tells you to tune your car to 14.5:1 is an idiot...maybe if it was NA
Rick
=====================================================================
TUNING SUGGESTIONS FOR 370cc injectors with a stock MAF
For both high and low throttle at each rpm point adjust the setting to ~-27% and thats it.
As for the decel air, just leave it alone for now you will need that only if you have an open atmosphere blow off valve...or a crappy recirc that doesn't open till 5 psi or so. Anyway the Th should be **** or 0%.
I didn't see a knock setting in the SAFC manual (http://www.apexi-usa.com/pdfInstallation/18.pdf) so it might not have one.
=====================================================================
INJECTOR SIZING EQUATION MADE BY ME, COVERTPOLARBEAR
To determine the flow correction injector percentage,
(OEM injectors/new injectors=X ::: 1-X=Y :: move decimal 2 over, and thats your percent.)
(270/370=.73 ::: 1-.73=.27 ::: 27%)
(270/440=.61 ::: 1-.61=.39 ::: 39%)
(270/500=.54 ::: 1-.54=.45 ::: 45%)
(270/550=.49 ::: 1-.49=.51 ::: 51%)
Engine fuel pressure at stock is 34 psi with vaccum hose connected
Engine fuel pressure at stock is 43 psi with vaccum hose disconnceted.
=====================================================================
MORE DEC AIR SETTING HELP
Hotwire air flow meter equipped engines do some funky stuff when you put open air blow off valves on them. The Decel Air function of the SAFC/SAFCII allows you to correct this. Once you have it set right, the car should stop backfiring or stalling on deceleration.
Start when the car is cold. (after an overnight rest is the best way, but at least several hours without running)
Turn key on, go to decel air settings.
Set throttle to 1%.
Set NE1 to about 4.
Set NE2 to about 5.
Start car.
Adjust NE1 until you get a smooth idle while the engine is still cold. Now start turning it down as low as possible while still maintaining a good idle.
If the car starts sputtering and getting rough, you just went too low. Turn it back up very slowly until it smooths out. You want to leave NE1 on the lowest possible point with a good idle.
Now set NE2 to be about 1 higher than NE1.
This formula should eliminate any stalling or popping from the BOV being open.
Theory: Throttle setting tells the SAFC whenever the pedal is depressed less than 1%, the SAFC should control fuel and ignore everything else (including the MAF)
NE1 is the first RPM point you have selected in your NE Point settings. I put mine at 1000 rpm. I set NE2 at 3000, then NE3 at 4000, and so on in 1000 increments. Setting NE1 down at 1000 gives you the ability to control fuel at idle really well. Besides, you probably don't need to adjust anything between 1000 and 3000. (turbo spools after that, right?)
Setting the air flow percentage at NE1 is basically telling the SAFC a number to use whenever it reaches that RPM and less than the throttle setting. So, as the throttle is let off, the SAFC looks at the NE1 and NE2 points. As RPM rolls back, there is going to be a reduction in air into the engine, yet the MAF has already seen it. The stock ECU is attempting to send the fuel for that air that is now missing... hence your stalling and backfiring. The SAFC catches that signal, ignores it, then tells the ECU exactly how much air flow you have according to your DEC AIR settings at those RPM points. Get it?
RPM comes down, hits NE2, SAFC sees 10%. It tells the ECU it needs 5%. (because you picked that number.) Now the RPM won't dive so hard like it was. It reaches NE1, SAFC sees 6%, you told it 4% and it tells the computer only 4%. The idle sets steadily down to where its supposed to and everybody is happy.
The SAFC is all about tricking the ECU into doing what you want it to.

Brown wire - pin 39 - black wire - Ground (closer to ECU 1cm from black SAFC wire)
=====================================================================
HERE ARE SOME SETTINGS THAT MULTIPLE MEMBERS HAVE MADE ON THERE SAFC POWERED RIDES
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)
-------------------------------------------------------------------------
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
-------------------------------------------------------------------------
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.
-------------------------------------------------------------------------
-27% across the board means that for each throttle point on both HI and LO settings, set it to -27 to make it basically equivalent to what the 270s put out for fuel, but you'll be using 370cc's so you need to pull -27% counteract the size change.
This is the setup I got from a fellow BillKlineVT

6000 | +17%
7000 | +14%
runs a bit on the rich side but it works good
-------------------------------------------------------------------------
right now I have it at -50 up to 2000 and the hi throttle to -38 accross the board, just to play it safe. by the way the rest of my setup is:
KKK K26 turbo
38MM wastegat
Walbro
Z32 MAF - Blow through
SAFC2
550cc injectors
People on the boards were telling me that the k26 was to small and not worth the time. I had the MAF maxed out @ only 7 psi. What HP level does the MAF max out at anyway. The k26 runs fine @ 12psi without dropping off so we'll see how high it can boost without falling off once I get the Wideband.
===============================================
I hope this helps more than just me.. but if not, oh well, at least someone may get some sort of info out of this..
thanks
Chuck

The biggest problems with these threads is that every setup is different. The main problem with SAFCs is the users fear of using it. People are so worried that they will set it wrong. There are no right or wrong answers. There is a fine line of safe and unsafe. Thats it. And that line moves.
Basically, if you have a wideband, there is no reason you need anybody elses settings. Go out and tune your car. Period.
But, damn, good of you to put in all that time posting to help people out! That is awesome!

well, i just put a list of every SAFC setting map i could find... so i mean you can kinda gauge where to start off (instead of just guessing)
glad its helpful to you guys

You may want to add that your not tuning for 11-12's all the time
It should be around 14-15 cruising, around 13 when crossing over from vac to boost, and then 11-12 in boost. |

| After reading this several times, I'm glad that Chuck put this up here. It's hard to find a listing of safc settings that people using the SR T25 setup are using. I think it's a good place to start for tuning this exact setup. |

SAFC can only correct for + or - 50% of stock injector size. Example: SR20 comes with 370cc stock so the max for that motor is 740cc.
Also, i like my conversion formula better ( NewInj - OldInj ) / NewInj |

TUNING SUGGESTIONS FOR 370cc injectors with a stock MAF
For both high and low throttle at each rpm point adjust the setting to ~-27% and thats it.

because the stock KA ECU is designed to run close to 14.7:1 AFR a -27% will make your car run close to 14.7 (too lean) under boost. to be on the safe side i'd recommend -20% to -15% across the board on both Low and Hi throttle |

Great write up but PLEASE note this is for an s13. the pinout was all wrong for me and my knock wire was tapped to the wrong pin.
Im also having issues running my 270's (putting in all supporting mods). are the sensor settings the same for an s14 as 13? i hade to cut back 50% just to idle on 270's.

just wondering, would an safc 2 plug up into the ecu harness that was used for an safc 1? been doing some searching and i was wondering if i could technically just swap out the safc one for the safc 2 without having to resauter the wires and stuff.......

mess around with these and your NEPOINT settings to get the car to drop rpms correctly

thats the same set up i will be running, but did he retard the timing or used at MSD BTM? thats the thing i am worried about. I dont know if i should save up and get the MSD BTM or just run without it.
and i am assuming he has the walbro fuel pump, right?

| Great thread. Although I am going to be using the old school SAFC, the one with no display, just adjustment knobs. Its not as good, I know, but it should work fine. On the plus side, there is no need to write settings down cause they can never be erased. It corrects + or - 30% and I have 370's. |

I too would like to know more about this, I'm gonna use the same setup aswell.
Will this set up be ok to run an atmosp. bov ( hks sqqv )
BTW:I think this should be a sticky |

hey i have a question too. i'm somewhat familiar with my safc, and the corrections are based on our factory injectors, thus 270/550=x, then x-1 to get our correction. Now what is that based off of?? For a ka the max is 550's on a safc, but on an SR the max is like 680. Is that based on ecu??
I don't know if that made sense, like my s14 has a jwt ecu for 550's and z32, does that mean that I can control bigger injectors with my jwt ecu?? So with my tune for the 550's and I bump up to some 720's would I be able to control them via safc?

I figured I better post mine since I'm getting AWSOME gas milage with 72lbs injectors.
Setup: Crower Rods, Arias 8.8:1(Stock Bore) Pistons, Ported & Polished Head, Crower Cams at factory settings, and all the typical Turbo Stuff.
I'm getting 28-29mpg HWY
AFC2 Settings
Lo Throttle: 2,000 -3,600 RPMs -28%
Hi Throtle is currently set to 0's across the board but I'm going to have pull some fuel out because I have black suit all over the back of my bumper.
This kind of Gas milage on a built engine is very suprising to me. I'm about ready to put the car on the dyno to see what she does. I just thought I'd share my settings to help with gas milage.
I didn't see anything on calibrating the Knock. I'd like to calibrate mine to work as acutately as it can
