Before going to my 1hr dyno session for the first since the s/c been installed to tune the a/f ratio.

I wanted to know what "basic" settings I should setup on the S-AFC before doing the Hi throttle adjustments at the dyno. By I mean all the other setting like sensor type, pressure type, and all that other jazz. There are a rack of things to set. I dont want to be wasting my time setting the stuff during my 1hr spot.

There are so many settings, shiet...... I dont know what the hell to set them to.

Any help would be appreciated.

Dixit,

I will PM you my info if you want to call me...

but you need to put ignition to on but not crank car.

select etc, car type, 6 cyl arrow up to right
settings, sensor type, hot-wire, in 4 out 4
Lo-throttle 39%, Hi-throttle 40%

I will be available tomorrow by cell if ya need more info...
I have yet to get to the dyno as I am stilld ealing with an o2 sensor not playing nice and the CEL won't clear out until it is replaced but hopefully soon.

 

What about setting like when you set the car to 6 cylinder, which way you point the Throttle Sensor Type? incline or decline?

On the graph scale what setting for intake pressure? and air flow % correction?

Two more questions, what is this Deceleration air settings for upper limits? Do I touch anything there?

And what rpms points do yall use when you tune? Like what 8 do see best chosen?

When I dyno tuned my afc it came out perfect. Gained 55hp from it.. My dyno chart is more inclined and less staggered. I have my settings at home. When I get off work I'll send you the info.

 

55HP from Dyno tunning with the SAFC, you sure about those numbers? I am looking at 6 thru maybe 15 HP gain. I am awaiting my ME VI, but I ll post the gains when I DYNO my car w/SAFC

 

I tuned my afc on the dyno. I did a before and after. Before 255fwhp, after 310fwhp.. I think I got so high #'s because I was running extremly rich. I have to lean myself out a lot on the afc just to get back to reasonable #'s..

 

I beleive I am running very rich as well...

I have not set any rpm related mapping...+ or -

I hope to arrange a dyno next week if possible to do some tuning.

 

You using aftermarket injectors? The only Dyno I did was at 5.9 PSI, and my car Dynoed @ 244HP. I was not boosting 10 since my belt was slipping. Lets see what the missing 3 PSI will do, the SAFC and the ME VI?

 

3PSI is alot.. Put it this way. Before I had my SC I only dyno'd a pathetic 155fwhp.. My car was definitely sick back then. Adding the SC with 3.33" gave me 100hp about 10-11psi.. And the afc gave the other 55.. So it's definitely something more left for you.

 

155whp? wait something has to be wrong there........ I just dynoed the car at over 183whp on my 2k1 auto. On a 3.33" you are getting 10-11psi? I thought the 3.125 gives you 11psi? That is what im running.

Dixit

 

what the? are you serious? you have all motor(not squeezing) 310fwhp just with the S-AFC?

 

All-Motor? Hell no, aint you read where he has a 3.33" that aint all motor. He got only 155 whp motor which is damn low.

 

Yeah about 1 month ago I dyno'd with all motor. At that time I had, intake, y-pipe, test-pipe, greddy evo catback/exhaust, udp. And all I got was 155fwhp. I ran it three times. The guy had like this meter that he connected to my exhaust. I guess it measures how rich you run. The meter was reading something like 14.5. Thats high, he sais it should be like 10.5 or soo. When I changed out my plugs they were black. So I know I was running super rich, I guess that would explain the 155fwhp back then.

 

That's would kinda be impossible to be all motor unless I had a 150 shot But I'm running a SC 3.33". Just threw on my blitz bov the other day and it seems to be running better with it.

 

whew...

 

Hahaha, sorry i just wanted to use that smilie.

 

On an all motor you cant be running at 10.5:1. That is too rich. All motor you want to be around 12.5:1 to 13:1. Something else seems wrong, seems like you might have had a VAIS problem. I would love to see the dyno on it to see what is the issue.

Dixit

 

no way.

 

The 10+psi of boost is what's got my attention... that shouldn't be possible unless someone wrote "3.33" in whiteout on the pulley...

 

You cant be pushing more than 9psi on a 3.33" 10 would be 3.25 and 11 would be 3.125.

Dixit

 

too high numbers for being running RICH?!?!

this reply is so lame, i'm gonna start dancin!

 

He meant he got such high gains (55Hp) because of leaning out the fuel. I think he was saying he was running too rich causing the low Dyno numbers.

Finally someone understands

For those non-believers I scanned the dyno's from before and after sc w/afc installed..

Before SC & AFC

AFC + SC

 

Only thing is that doesnt show the difference that the safc makes.

 

not to doubt that you gained the hp because i don't but that dyno is uncorrected. it should be SAE corrected like your first one. you hp numbers will prolly be slightly lower. if you go back and get them on disk you can play with it at home using the viewer...


no disrespect intended just trying to help.

 

Also the reason why the first dyno #s are soo low compared to others with that much mods is that they dynoed it in 2nd gear. You can tell from the mph on the chart. But what is wierd how the 2nd run is like 86mph. Cant see how they got that speed on 2nd gear on an auto. Cant get more than 70-75 on 2nd gear.

Only question I got is the 2nd dyno done in 4th or 3rd? If it was 4th then maybe that is why the #s are slighly higher than normal.


Dixit

 

Actualy I think the SAE corrected was 297.9. Uncorrected was 310.6...

 

The second dyno we left od off and did it manuelly shifting, also od off and left it in drive..

 

But what about the 1st dyno. Was that in 2nd?

Cause im lost now, I thought dynoing in 2nd would give you lower number but im being told it would actually give you higher numbers? What is the right one?

 

Now thats sounds a bit better since I woke up this morning and said something is wrong with those 55HP gains out of a SAFC. I now see why your numbers are a bit different, plus your auto. Have you taken it to the track to exercise those 297Ponies?

 

I only went to exercise the 255 when I didn't have the afc.. So the extra ponies should make a difference now... I think I ran a 14.5 last time. But I didn't do anything to the car. tire psi etc.. left it street..

 

I've tried following this since I have an untuned AFC myself, but I'm a little lost here. First off, is your car a 2k or 2003? noticed it was an auto, but why would you dyno in different gears? Auto's should dyno in 3rd w/o O/D, correct? Also, why would you be running rich or lean N/A? If you have only bolt-ons, you at worst would run slightly lean due to better/more intake, not rich.

I'm not trying to put up the B.S. flag, just doesn't make sense. It's hard to really see the kind of gains you're talking about if you use skewed numbers to begin with. I know it's probably impossible to do now, but to really see the gains of the AFC alone you would have to have a baseline before/after (with the same gear pulls, same add-ons, etc....only diff is adding the AFC).

 

He was actually talking about running very lean when he had it dynoed intially at 255whp. That is when the s/c was on with a 3.33".

The first dyno is straight NA.

Dixit

 

If his numbers seem too high then what are common gains you guys have found when properly setting the S-afc? SC'er? Nitous?

Hello I just installed my SAFC as well and was wondering some of these questions. I wonder if we should make a sticky for the basic settings for the SAFC since it's so popular. Or at least on thread will the settings to do a search on.
