I DID SEARCH!!

Ok I am running a paxton FMU right now, when I go to put in my SAFC and bigger injectors, I should get rid of the FMU. That is what I think, but everyone around here says keep it in, I think they are losing it or something. What should I do, anyone with experience here?
BTW car is a d16z6 with a 16G turbo and side mount intercooler. Already has 3 check valves installed and I am running 8 PSI. Need some help finishing it off, just got it running two days ago. I Have everything to put in the injectors and the AFC is already installed but settings are set at 0. I alsl have a AEM FPR that I could put in to help out with pressure.

one last thing, the guys that are telling me to keep the FMU say that I need something that goes off boost. But I think that with bigger injectors and bigger pump, and being able to lean/richen the injectors I will be fine and have no need to run so much more pressure in the rail. Any info would be cool, thanks.

 

bump, kinda need a short answer by tomorrow. Thanks

 

with my first setup tuned by inlinepro, i had safc, fmu, 310cc injectors on my stock d16z6 ~9psi of boost. I'd say keep the fmu until u can get some better engine management.

 

im running the afc and fmu setup too. people tell me to keep it in so the afc dosnt have to do all the work.

 

inlinepro told me to leave it in b/c you want something that will change along with the boost pressure.

A friend of mine had his car running with a similar setup safc/fmu but on a gsr tuned by inlinepro also and he ran 11's.

 

bump. i had to get the safc and i want to no about needing the fmu with the safc too. by the way where did u get tuned? dynamic motorsports?

 

I wouldn't take it anywhere. I do all the work myself bud.

 

the only reason you would keep the FMU while using the AFC is because you have small injectors, example 310cc. I recommented getting some DSM 450cc injector with the AFC and put the FMU in storage. I ran with the 450's and the VAFC on my 00 civic SI with a custom turbo kit that I built w/ a garrett T3/T4 56 trim turbo. The car ran great. It was tuned at abacus and I put down 287whp on a stock 00 B16 w/ a greddy exhaust. I have a website that shows you how to setup the AFC if your going to use this setup.

 

I already have the AFC in the car, I am just going to keep the FMU in and if I can't lean the 450s out enough it is coming out along with the check valves. I really don't think I will need the FMU but I am keeping it in to keep people happy, it can't hurt to have too much fuel unless you can't lean it out you know.

 

do you have that link...id like to see it...im running a custom t3/t4 kit and i have the FMU just installed SAFC no injectors though and no added fuel pump...im guessing im just gonna buy the 450s or sumthin...im hoping to be tuned by the 28th so i dont know which route 2 take...if u can get the link itd be sweet..isnt it the AFC hack or sumthing..thanks
