Help with VAFC Hack

[B16eh2]

I have been reading around on the net for a while trying to find a ok way to "street tune" my vafc to increase fuel so that I can be semi safe driving around town on 8-10psi untill i can purchase hondata an get to the dyno.

I see that people have done this before, Im just not understanding what settings to go into to increase fuel. Has anyone done this before or know how? Thanks for the help..

Setup:
B16a block
ARP head studs

Gsr Head
Stock Injectors
billet fuel rail
Skunk2 I/M
Hondata I/M gasket
GSR Cams

Ram Horn Manifold
T3 Airresearch .42 .48 Internal gated
3in D/p
FMIC and 2in hard pipes

Management, VAFC I

look thru the manual it should indicate where the a/f is.
its easy man i had it on mine but!!!!!!!! they stole it
which one do u have the apex vafc the black one? thats the one i had.
btw wat year is ur ride , see i notice u got the skunk2 i/m
im trying to get one for my ride i got the b18c1 gsr in my 95 civic.

(I just added a couple pics for reference, Look at first post)
No I have the silver one, The first Vafc. I was hoping some one could give me a little walk threw with the settings as which ones go where Ect.

wen my ride was single i had the pro series and it would hit the proportion valve of the brakes thats why i was a lil concerned.
awesome set up!!! so u got the old one huh?
i wanna get the new neo but first the the pro series!

There is no problem with mine at all. Even when I tore my mounts it still never hit lol. I like it much better the the stock manifold although I never had it on, I just like the design of the skunk versious the gsr. IMO the gsr manifold seems to have a horrible flow design not to mention the butterflys in the middle.

Any how back on topic

would u know if a h22a tb will fit on the pro

you cant use stock injectors, they wont flow near enough fuel even when increasing the duty cycle from the VAFC.

Im not looking to go out race with it, I just want to increase the flow enough to handle daily driving needs.

All Im asking is if some one can tell me what to set the settings at to increase the flow is all?

you are a bit unclear of the concept.

what a VAFC hack is, is using large injectors (larger than stock) (usually 450cc) and scaling back the fuel delivery of the large injectors to flow normal amounts under no boost situations and when you enter boost the large injectors will increase their flow and being that they are quite large they will have enough flow to sustain fuel delivery for the boost level.

if you are using stock injectors you will have to increase the fuel delivery, this will likely limit your boost levels to under 10psi, as will the hack.
stock injectors cannot safely handle 10psi with the amount of timing advance that the vafc introduces.

the way to increase fuel is increase the number in the vafc.

for example, if you want more fuel and its set to 0 across the board, if you set it to 20 across the board you will be getting 20% more fuel.

if you have 450cc injectors in a stock d series typically they are set to -38, this is because the car would not start or run with 450cc injectors because they push too much fuel, so the vafc limits the fuel by 38%.

do more research before you blow your motor.

i would suggest getting large injectors and getting a basemap for the injectors and setup, at least then you will have correct timing and smoother in and out of boost, as well as no cel under deceleration in vacuum.
