Would an SAFC do anything for N/A KA?

say you got a full exhaust system including headers, standard cold air intake, and maybe some cams.

would tuning with an SAFC bring out any extra power?

I say the more HEADERS that you put on the more effective your SAFC will be. Get a vtec controller too.....

I really dont know. Cams would give you more power.

SAFC gives you fuel. Cams give you air. Fuel is the easy part. Air is the hard part. Thats why people use turbos...

SAFC is worth 10whp maybe.(once you say a number, the guys who really know will correct you...)

ive heard claims from a dyno tuner, na ka peeps with headers, exhaust, intake + safc = 10-15whp, depending on engine condition, ambient temp and all the other varibles. now if you throw some cams into the mix and change the individual cam timing, adjust the fuel curve......... id be interested in the results

I dyno'd one on my car. We were lucky to get 2hp out of it.

Not the threadjack, but I have a very similar question. How much good would the AEM standalone do for a NA KA with intake, header, exhaust, cams?

Well, you could get more out of it if you put on a larger MAFS and a N15 pulsar throttlebody on your motor. Its 70MM (huge!!) and Any tuning you do with that would yeild more than 2HP...

The SAFC is really just a half *** tuning unit. it only tricks the ecu to see more air therefore throwing in more fuel. It does not accomodate ignition timing adjustment to go with the new amount of fuel going in so it just a half-*** show peice in th end. The best way to go if you dont want to spend the cash on the AEM is get a JWT chipped ecu and the SAFC to fine tune it becuase they change your ignition timing maps to suit your mods much better. Other than that, it wont yeild much of anything-Chris

Personally I like the S-AFC. An investment that grows with your list of modifications instead of having to spend a few hundred for the JWT chip and having to get it reflashed everytime you go with something new that will change your air or fuel flow rates or without the heavy initial cost of the AEM unit. It's definitely not something that'll get as much power as lets say a turbo but it is alot more flexible than a JWT chip and much less costly than the AEM EMS. Definitely a unit to fine tune without the commitment of the AEM (cost) or JWT (not adjustable without major inconvienence). The AFC gets my thumbs up with all that's considered.

well actually, despite the facts ive stated a couple posts up, ive have seen it give good gains and is a descent device for very mild tuning with bolt ons. But any serious setup should at the very least get a JWT+SAFC to tune or the AEM unit. Actually, AEM claims that with the DC header and short ram intake and AEM stand-alone, they got 27 horsepower (at wheels i believe) on a stock KA24de. That is quite impressive and shows you the power of stand alone tuning. Now think what high compression, hotshot header, pullies and some ITB's could do.

EMS will give you much better gains. You can control everything from timing and duty cycle to the nighlight in your bathroom.

I believe they got 27hp from it...

There is a pretty cool demo version of the AEM EMS you can get off of AEM's website. I got the program, but the instruction manual that came with it didn't work so I was clueless as to what I was doing, but it was nice to get a look at what the program looks like.

Not to threadjack, but 2BN_S13, how hard is it to do the N15 Pulsar TB? Is it just a straight forward install or does any fabrication go along with it?

HahAHAHA... what's with the noob flamin'???^^^

anyways, you could also try a program called "MegaSquirt". I ran it off a laptop to my diagnostics port on my NA saturn...

With all these F&F kids runnin around with civics and every possible bolt-on they can find, it's rare to see someone actually tuning the car also.

I respect what you doin' man... kept messing with the ecu on my satty til I had the a/f ratio to stoic (it had been runnin too lean.) And it does help s-afc, or any of those...

so basically, if on a budget the Safc would be good, but if money isnt that much of a problem AEM EMS or JWT Ecu would be tha way to go

i didnt see quite the same gains as they did. i ended up with 152/164 with the ems/header/catback/intake/and udp on a dynojet. that was with the basemap loaded though (pretty rich), im pretty sure ive pulled a little more out of it now. hopefully the next time i dyno it will be at 10psi , but i might after i get it running with a map setup as well.

don't you have an S14? i think the less aggresive cam profiles probably have something to do with it showing less gains.

correct me if i'm wrong.

I agree.. I have an S-AFC and for me, it mind as well be a damn vtec controller because I have no idea how to tune it. Chicks dig the blue screen though

SMT6 is a pretty good piggy back compared to the SAFC. You can actually mess around with the ignition timing, I just bought an SAFC because I'm a compulsive spender and it seemed good at the time.......

SAFC helkps you dial back some of the excessive richness of our stock motors= more power and better MPG

Yeah I plan on getting one and I figure if you can tune your A/F ratios to stoic (14. something to 1) the power gains and better gas mileage can't be complained about. Overall I think its a great product for mild tuning

Hey and while we're at it you guys look at these:

I kinda like the Greddy but the description for it is too vague for me to just buy it. The blitz looks pretty good too but it looks ugly

i got an SAFC II because i was gonna boost in a month but something came up so now i dont have enough funds for the set up. I started to mess with the SAFC on my stock KA, tryin to get some better MPG. anyone done that? if so what are u running on ur map across the board? i think i might be leaning mine out just a little too much on low throttle. i think i have like -4 and like -3. anyone else?
