b16 turbo setup FMU OR NOT TO FMU
Heres the setup so far I have a 91 civic with a b16a, zydene ecu, walbaro 255, crower titanium retainers and crower springs, everything else is stock. I have a t3 turbo, ordering a lovefab manifold, and dsm 440 injectors. Im only gonna boost 6-8 psi and its alow buck build up. I was wondering what i could use for fuel management and for ignition. Im not really up for a vafc hack but i have read there is a way to use the vafc hooked up normally and changine the settings to a desirded about but i didnt know if it worked with a b16(seemed everyone was non vtec sohc) I have heard alot of bad things about FMU's so i really dont know what to do. ems are kinda out of the question since im obd0 and im on a restricted budget. any advice opions or anything else is very appreciated.

Re: (mattb16a1civic)
well i boosted 7-9 psi for a year with just an adjustable fmu for managment..........worked great for me..... but on STock injectors, and jsut an upgraded fuel pump.
actually u might run TOO rich with the fmu and dsm injectors............for jsut running 7psi u dont really need the dsm's cause without managment to control them, u wont be able to lean them out.. but keep the injectors handy for whenever u go up to say 10 psi or something... and then get an smc, or safc to use with the injectors and u will be set..
so yeah use the fmu with ur stock injectors and the rest of ur mods (minus the dsms for now) and u could run 7 psi all day long
(8psi might be pushing it, but just remember to retard ur timing more if u go up 8 and u should be fine).. dsm injecotors would solve the problem of going up to 8+ psi but u really need something to lean them out at idle and low throttle or ull be dumping gass out the ***...
for doing low budget/fast performence

Re: b16 turbo setup FMU OR NOT TO FMU (mattb16a1civic)
FMUs work great for applications boosting 10psi and less. Above 10psi, your fuel pressure will be too high for every day reliability. With 440cc injectors, go with a 4:1 or 6:1 FMU to keep from running too rich.

Re: b16 turbo setup FMU OR NOT TO FMU (ben@importparts.com)
I'm running a V-AFC, RC 440's with a 12:1 FMU on my LS/VTEC and my brother's GSR with no problems. Most people will say too much fuel pressure...but it works and if you search around there have been people making 300hp + to the wheels with this fuel setup. Driveability is maintained by leaning out the V-AFC in narrow throttle to -30% to -40% depending on setup, and wide throttle is tuned on a dyno. Its may not be the best fuel setup, but it works.
P.S. - This is not the V-AFC hack, you still use a missing link.

Re: b16 turbo setup FMU OR NOT TO FMU (Chrome Pipes)
Definetly agree with everyone else. I ran 12-13 LBs with the FMU (8:1) fine with S-AFC.
The only downside is that there is no ignition retard but since your'e only gonna run 6-8 PSI, that'll be FINE.

They work really well with low boost cars. using the stock ecu to idle and run aprt throttle maps...IMO FMU works great for 10 psi and less..like ben said.

Im still indecided either use the vafc idea from this thread https://honda-tech.com/zerothread?id=137901 and dsm injectors or go with an fmu and a missing link. Dont really know all the advantages and the disadvantages. I t hink the main thing i want is driveability and the second thing I want is an economical system.

Re: (mattb16a1civic)
I will be boosting my d15b7 soon with the fmu and inline pump. The guy that's selling me his setup said he ran fine as long as it's kept under 8-9 psi.

Re: (ben@importparts.com)
The hack or the FMU would be fine for your boost levels. Hack has more reliability because it does not force fuel components that were designed for under 45psi work at 100. the hack also can have some hesitation at light throttle but most cars (that i have setup) don't have this problem. Fmu is not rpm adjustable at all, hack is. Neither address ignition timing but as it was stated it won't really hold you back at 9 psi or so. my.02

Re: (PHiZ)
I had fmu on my ls integra and i hated it. It is the worst way to do your fuel managment. It works but shity. So permanently you can run fmu 12:1 disk, stock injectors up to like 8 psi. But try to save up for standalone or piggiy back.

alot of things suck for obdo and I really dont wanna get rid of my zydene, Im kinda partial to it, mainly because it was alot less hassles during the wiring, std-b16. as to turbo happy i was in auburn and no im not driving my car Im in the middle of an engine rebuild waiting on bearings from honda. IDK still undecided its either fmu and missing link or vafc and injectors..... as of right now I still havent any clue to which way ill go.

Checked a map and I guess Auburn is N of Fort Wayne. So no, I guess I wasn't there Kind of confused me since I did autocross in Indiana on Sat/Sun, just at Columbus region

Re: (turbohappy)
Is it me, or are all FMU that i have seen, run like crap, they don't idel well, and they sound like crap. FMU = Ghetto, so much better stuff out there, but if u are straped for cash, and want to have fuel mangment go for it
