Your Turbo System & SAFC Settings

Post by **side waz** » Sun Oct 23, 2005 5:50 pm

**** 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.

Easy

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.

Post by **Tx-Sx-FS** » Mon Oct 24, 2005 8:24 am

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

Post by **side waz** » Mon Oct 24, 2005 10:26 am

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.

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.

Post by **1WheelWonder** » Mon Oct 24, 2005 1:24 pm

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.

someone sticky this ****er please.

Post by **crzycav86** » Tue Oct 25, 2005 7:14 am

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.

Post by **dj_hype** » Tue Oct 25, 2005 7:17 am

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

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.

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

Post by **1WheelWonder** » Tue Oct 25, 2005 10:39 am

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

Post by **fiznat** » Tue Oct 25, 2005 11:03 am

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!

Post by **Deadrodent** » Tue Oct 25, 2005 9:28 pm

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

Post by **Craving4Boost** » Tue Oct 25, 2005 10:49 pm

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""

You mean backfire?I think this would help if your stuck in traffic a lot like me...85% of the time.

NEed help with my settings... I am not really familiar with this but how do i check if the setting are right or wrong???

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 currentSAFC settings are:HI map +22% all pointsLO map +23% all pointsDEC AIR : was Thr ****%, Ne1 10%, Ne2 10% now 1.1 ne1 1.4 ne2 2.0TH point: 44%, 45%and my air/fuel readings are really unstable at idle...

what is wrong with this bomb for being dumb...

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.

Post by **WDRacing** » Thu Oct 27, 2005 11:40 am

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.

My most recent settings:

Hi Throttle: +25% 1000-2200, +30% 2800, +40 3400-7600Lo throttle: +23% 1000-7600Throttle: lo 10%, hi 35%dec air: 1.1% ne1 1.4% , ne2 2.4% --> 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??

Post by **side waz** » Thu Oct 27, 2005 4:12 pm

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.

Post by **deathBooster** » Thu Oct 27, 2005 6:44 pm

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

result:4000rmp -> 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????

Post by **deathBooster** » Fri Oct 28, 2005 5:42 pm

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..

Post by **1WheelWonder** » Sat Oct 29, 2005 3:58 am

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.

Post by **side waz** » Wed Nov 09, 2005 4:44 am

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.

Post by **deathBooster** » Wed Nov 09, 2005 5:58 am

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..http://www.roadraceengineering.com/newafc.htm

Post by **side waz** » Wed Nov 09, 2005 4:44 pm

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.

Post by **deathBooster** » Wed Nov 09, 2005 5:17 pm

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??

Post by **Mustangs_Suck** » Fri Nov 11, 2005 8:56 pm

When my car was tuned at the dyno, the hi maps were all +30% and above, while the low maps were -27% and gradually risen.

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.
