S-AFC & FMU
 

I have an SAFC and a FMU in my 90 integra and it has DSM 450 injecters, i was wondering if i still need the FMU with the SAFC?

Re:S-AFC & FMU
 

Nope... there's no need for an FMU if you have the afc.

Re:S-AFC & FMU
 

what can i boots it with the afc without ------- up my motor it a b18a

Re:S-AFC & FMU
 

I dunno... Around 10 psi or so if it's properly tuned should be fine.

Re:S-AFC & FMU
 

ok i dont need the fmu do i need the check valve to? i want to do 12psi fo boot on my car

Re:S-AFC & FMU
 

No check valves and if it's tuned well 12 psi should be fine.

Re:S-AFC & FMU
 

how high in boots can i go with no check valves

Re:S-AFC & FMU
 

What's all this talk about boots? ??? :P You don't use check valves/missing link with the AFC. How high in "boost"? How high do you want to go? The AFC can handle more than your motor can. If you're running stock internals on a daily driver, I wouldn't go much past 12psi, depending on the turbo.

Re:S-AFC & FMU
 

right now im running a stock b18a motor, i was just wondering how much boost my motor can handle and im going to be rebuilding me a new motor for performance but i need to know how much a afc can handle on a built motor. i want to do 12psi in my stock and i want to do 20psi on the the one im going to be building, so i need to know what the afc can do cuz im new to the afc.

Re:S-AFC & FMU
 

I would get some good fuel management if I was boosting 20 psi on a built motor.

Re:S-AFC & FMU
 

if you run a afc, can you do away with the missing link?

Re:S-AFC & FMU
 

YES! Lol... Did you even read this post? ::)

Re:S-AFC & FMU
 

<<<ok, ill go drive over myself now, my bad>>>>

Re:S-AFC & FMU
 

Lol, yeah like beerbongskickass said, I would get some good fuel management for that amount of boost. The AFC is cool for the normal amount of boost, but if you are going crazy I would suggest something better(Hondata, TurboEdit, PMS,..)

450cc, AFC, BTM, and 4:1 FMU can be played off against each other to support 400+ whp. Not my ideal control platform, but it's been done with reliability and stable AFRs.

Re:S-AFC & FMU
 

Yeah, TurboEF9 was running pretty high boost with an AFC. I don't believe he was using an FMU along with it. I suppose it can be done with positve results. I would just want something better to boost that high with a built motor. :-\
