I am getting an apexi safc soon and I was wondering how people have been tuning them to get the best results? I know some people think it is BS but I have heard from others that it can show gains. Any comments would be helpful. Thanks.

 

Ummm....why do you need this? Are you running a turbo? SC?.....
If not....i would have spent the money on the safc.....maybe got something the will positively give you gains.... Like nitrous.

 

The S-AFC will give gains to a NA maxima.

 

What kind of numbers? Enough to make the 300 or so worth it?

 

small gains....but at least its a pretty blue color!

 

I will say some where in the 10 HP range... depending on what else you have done your car.

So 10 HP worth $300 to you?

If you spent $150 on an intake giving you 5 HP... then 300 for 10 is not out of the realm to me... BUT what is it worth to YOU?

And if you have I/Y/E/VI... I think it would be right on the money... unless you wanted to save for a larger mod

 

Plus some people like playing the NA game for what it is worth.

On this VERY SITE.. is a brilliant write up by Keven97SE on how to tune an AFC ... now i have given you his name and the topic.. now i am not going to tell you how to find it

 

I probably wouldn't bother unless you are boosted in some way. Put the money towards nitrous or something else!

 

Hmmmm


Dammit bags.....now you have me wanting one!

 

who on here gained 10hp N/A from an AFC?? and with what mods??

 

did not say on here... and basic bolt on's

 

where did they make the power at?? what were the optimum points on the band??

 

Can you tone down your sig, it is FN huge and takes up space, besides 90% of the things listed people done got already.

 

Wow sprint you know everthing.

 

it has been mentioned a few times...no luck.

 

from my understanding there was a 3-5 HP gain through out with 1st/street setting and " about 10 peak HP " on the 2nd/track setting

 

interesting...a buddy of mine made ~11-12fwhp throughout after adding the AFC to his VG with P/P heads, Euro cams and bolt-ons! I wasn't doubting you, just curious to see where the gains were....

according to some of the guys on the SE-R boards the secret(if even anymore...) on most N/A Nissan's is to slightly lean out the top-end...personally I'd never try to tune one of these on my own...

 

I wish i knew the guy better who did it. I have been thinking about this for awhile... there is a shop here in atlanta the specializes in nissans/240's and they sware by them.. If I were looking at staying NA I would have one ASAP.. but I have a larger purchase in mind.

cool.. I did not know any VG's had them

 

I'm planning to get the S-AFC too. Probably my last mod...since I'd want to tune just right with my other mods. I was told by an experienced tuner that I'd see 8-15HP and mileage will increase. He said adding an intake should naturally lean out the air/fuel mixture...didn't ask him about the affect other exhaust components had on the ratio though. Looking at my exhaust tip under normal driving conditions, it appears to run just fine. When I do some constant heavy driving, the tip gets really sooty, probably running rich. Anyways, I was planning on getting the S-AFC if and after I get the MEVI.

 

An intake won't make the car run lean. It's MIGHT be possible to have enough na bolt ons to make the a/f lean but that would only happen when the car is in wot open loop program and you were flowing upwards toward 30% more airflow. But that would take an intake/headers/cams/larger TB Y pipe/cat back etc...

 

only because i search

 

don't sleep on the well tuned VGs...we've got some secrets up our sleeves

 

no I do not.. with Variable timing and intake.. I know there is some power there

 

no no, he said slow poke vg.

 

hmmmm...this particular VG was an auto and running with VQs...so slowpoke, I'm not sure about that one.

yeah the VG doesn't have VTC, but we DO have variable intake...Nissan didn't start being cheap and taking good things off of their motors until '95 and later.(j/k)

 

i have seen the 3rd gen 1/4 mile times thread

 

haha.. yeah I mxed up VG & VE

 

low blow man ...yeah, well we have our few quick ones though...
