i'm sure someone has a either a SAFC or VAFC with a turbo. i want to add some more fuel when i get boosted but not have to get bigger injectors so i thought maybe the "piggy backing the ECU" way might work. my main goal is to run 10psi daily and maybe 12psi at the track (all this after i do some internal work of course) would these work for up to 10psi? or would they work period with stock injectors?
and i thought the VAFC had a problem with our cars because of something but i dont remember what or i might be wrong all together lease:
did they or someone find a way to fix the problem whatever it may have been?

with our fuel kit alone you can run 12 psi. If you add the SAFC to the mix, you may be able to squeeze a little more boost out of it, but with the fine tuning, you will be able to make more power all around.

get the s-afc idea from me? LoL

the vafc wont do anything for you thats for v tec...the safc will...

exactly

haha, i cant have you running more boost than me, i wont allow it!

LoL, Jon saids we should have a 3 way race, you with turbo, him with no turbo and no nitrous, and me with turbo and nitrous lol.

He also saids you wont run me if i use the bottle

 
Rep Power: 401

jon racing us with no turbo or nitrous, LOL, so it would basically be a race between me and you then. i'll race ya with your nitrous but i wanna run w/out just to see if your CVT makes a difference.

BTW if you find any directions for installing your SAFC let me know, its gonna be my next purchase after boost controller.

theres a DIY for the s-afc in the DIY section and i would recomend the apex avc-r if ur going to be boosting. some info http://www.apexi-usa.com/electronics...aloverview.asp and the v-afcII works fine on 01-03 ex's

 
Rep Power: 584

are we sure about that bc i think u can adjust fuel with it, the only difference between the two would be one can control vtec and the other cant

also the avcr doesnt control fuel, it controls boost

 
Rep Power: 0

why would u recommend the avc-r? it doesnt controll air or fuel.... i have the avc-r .. and its a bitch to tune..

 
Rep Power: 0

what the hell are you talking about doesnt vafc mean vtec air/fuel coverter? and safc mean super air/fuel controller? or something basically works the same if not get the v-afc 2 if and I mean "IF" it works with d17's

 
Rep Power: 0

both work with our cars.. and no vafc doesnt mean af converter.. lmao ... its probally like variable air fuel CONTROLLER.... it controlls vtec engagement points and same as the s-afc... air and fuel

 
Rep Power: 351

crap ur right hahaha i thought it did cuzz u can control the injectors with it. but yes it is a bitch to tune and should only be done by a pro @ a tune shop. still think its a good over all tool if ur going to be boosting IMO have a couple of freinds with GSR's and they are all boosting and love the avc-r

 
Rep Power: 0

dont get me wrong.. i love the thing.. its just a BITCH to tune... to set the duty...

 
Rep Power: 0

wrong... the vafc can do all the things the safc can, and also control VTEC engagement

 
Rep Power: 0

no prob, ill tell you if i can get the s-afc installed even though the instructions i have are in japanese lol. I think i may have sf do it if i cant. Also ill run you without the bottle, my turbo vs your turbo first, would be a good match up lol. you have an ex right? 10:1 compression, i have 9:1(hx), which means ill be able to boost a lil more than you . Anyways i dont want to use my nitrous with my turbo yet just cause i need smaller nitrous jets lol.

Also Jon is pressuring me to sell my zex kit to him when i get my turbo on this month LoL

dude its so easy to install the s-afc... all u have to do is connect up to the wires coming out the ECU... check the DIY section.. shows u each wire..

 
Rep Power: 312

Ok question time. Will the S-AFC control duty cycle to the injectors? If not, how does it allow more fuel to be added at higher boost? Choices for fuel setup right now are: the S-AFC, Aeromotive digital FMU, E-manage, and the ERL MF2.....Of course that's BESIDES going return.

But hey - has anyone here even gotten the E-manage to work properly? I see that a lot of folks on the clubrsx forum are having difficulties getting things squared away.

Zinky has the MF2, which works great if tuned properly.

So far no one claims to have the Aeromotive....But it does look like a good choice!

man i hear ya... and dude i love where u mounted it...now i have a new idea of where im going to mount my s-afcII. 1st place i was going to mount it was going to be on the driver side, on the window right at the top b4 the headliner by the sunvisor.

S-AFC "hack" explained. Makes sense to use larger injectors.....Wonder if anyone has tried this on the 7th gen yet....time to utilize the search button!

 
Rep Power: 584

the hack? or the injectors? im using all 4-440cc injectors

 
Rep Power: 401

damn now i'm lost, you all got me confused on what does what now, lol. so the SAFC does controll fuel, but it also controls VTEC? cuz this is what i was planning to buy. is that a good or bad idea?

edit-i should add i dont care about vtec engagment, all i want is to add a little more fuel

 
Rep Power: 334

SAFC = SUPER AIR FUEL CONTROLER

V-SAFC = SUPER AIR FULE CONTROLER + VTEC ENGAGEMENT POINT CONTROL

id say if u have an ex just get the v-safc and if not get the regular safc

 
Rep Power: 584

the AVCR controls duty cycle

 
Rep Power: 312

You are still using the emanage, correct? That does essentially the same thing that the S-AFC does in terms of signal, right? I know that the S-AFC doesn't control ignition timing, but the Emanage is supposed to. Its a shame that Apexi has a different box for this (not even sure if it supports our cars or not).

I'm really curious to know, using this method of "tricking" the computer (aka the "hack"), how much off the ignition timing really is? I mean, reading a lot on the honda-tech forums, you have to make darn sure that you aren't getting pinging because of a fubared setup.....

How are the 440cc injectors working for you? I see that others were having problems and tried to stick with the stock ones....Did you get them from RC engineering?

 
Rep Power: 584

yea they rc engineering, it took serious modifications to get them into the stock rail position. but then again i did the return so, they took the fuel system out and modified the whole thing. as far as how they are working, i guess they are fine, i dont do the tuning so i really dont know, i do know that im under 60% duty cycle so i have some ways to go before they are maxd out

 
Rep Power: 351

this correct and just to add to this the s-afc and s-afcII work fine with our car ex,lx,dx
the v-afc not v-safc has some peoblems with our car but the v-afcII works just fine with the ex. no need to get it for the lx,dx because of no vtec.

 
Rep Power: 312

That's cool! You know, I've been reading (whoring) as much information about the S-AFC and the e-mange at honda-tech. So far the E-manage LOOKS like it would be a far better setup than the S-AFC. But I hear its a beeyatch to tune. You said you have a tuner do it for you?

Did you ever get the ignition harness / tuning to work? I know that running boost, I would def want to retard the ignition high up! Do you have the missing link installed too, or are you using the E-manage to regulate the incoming MAP sensor voltage?

 
Rep Power: 584

i have the missing link in there yes, i wont know about the ignition til the end of this month, bc thats when i get the car back, my shop is 200 miles away from where i live now. so it takes some time to get it there and get it back. emanage is a tuning pain ill give it to ya, having to sit in the car with a laptop trying out different combonations of things and seeing if they work.
