Sup fellas i am currently in the process of tuning the emanage for my turbo prelude and it is very tedious....thinking of goin with the vafc hack instead
IF I go the vafc hack route with the vafc, 12:1 fmu, rc 440's, and fuel pump, what fuel pump should i be using?(I currently have a intank 255) Will i need an inline as well to support the fuel? Can this setup support 11 psi?

 

A in tank 255 should be able to support 11 psi fine. I also have a 255 and at certain times I was running more boost than that.

 

k thank you , im guess ill be going the vafc route now since the emanage is more pain to tune, what is your setup?

 

You don't need the FMU with the VAFC hack setup......the 255lph in tank will be fine for fuel, and you'll need something to adjust the pressure with (like an AEM or a B&M regulator) if you don't already have one....

let me just clarify
FMU=INLINE pump
Injectors=INTANK pump.

and yes a 255lph will hold 11psi fine if its tuned properly

I was going with this setup because i asked other turbo prelude owners and they were using the same setup vafc, fmu, rc 440's, fuel pump? does anyone else think this setup is correct? i seem to be getting mixed info

 

now i just found out the 12:1 fmu will be running too rich? i was told to get a 6:1 fmu now or a sfmu?

 

2000typesh what is ur setup now for ur fuel. how easy was the tuning?

 

all u need to run for the hack are 440s and vafc, no need for the fmu or intank, that will cause u to run to rich, im runnin the hack right now.

for 11psi, id get the gm 3bar map sensor since u will most likely get a cel past 10psi.... ive yet to get cel and ive gone 12psi, but im at 9 daily now

 

sounds good saga, im at the shop rite now, goin to take the emanage unit out now and out in a vafc and let my ace mechanic tune the fuel with the fjo wideband. thanks

 

are u using the msd to retard timing? thanks

 

what exactly are you "hacking" by using a V-AFC with a turbo setup?

 

nope.....

 

map sensor out put signal
