why is fmu SSSSSOOOOOO shitty?
 

why does everyone say that fmus are worthless and such? i mean its better than nothing right? some of the high dollar kits like rev hard come with them. granted ecu tuning is exponentially better, but whats wrong with running an fmu till i can buy a chipped ecu from xenocron. not saying you guys are wrong or anything, im definitely here to learn, i just wanted to know. ya know?

Re: why is fmu SSSSSOOOOOO shitty?
 

ya it should be cool for a low low boost set up make shure you have a wideband or at least one of those rice a/f ration guages hooked up to your stock narrow band o2 sensor.. so it wont lean out on you make shure it stays on the farr green side (rich)

Re: why is fmu SSSSSOOOOOO shitty?
 

Because you have to run stock injectors and there is no timing control. Also revhard kits are basically garbage.

Re: why is fmu SSSSSOOOOOO shitty?
 

They suck because most OEM fuel pumps suck. Too much boost, and your pump screams for mercy. You also have no timing control, unless you want to install a crude timing retard gismo like MSD sells.

As for the kits, they do that they *know* half their customers would ---- things up if they had to touch any wires, and get a bad rap from it. It also prices them more competitively, and if you can sell soemthing that much easier than the 'other guy', regardless of a kit's incompleteness (of which they can't return w/o a restocking fee), you make more money. As you know, thats 1 of the 3 things this world runs on, besides ----- and oil. :8

Re: why is fmu SSSSSOOOOOO shitty?
 

Believe me, even with an FMU..on a low boost setup, FMU's will still make everything a headache. And its not just (oh the car runs rich) sometimes it will run rich enough to complete stall the motor, if the rpms drop, the motor wants to stall, at higher boost the A/F is all over the place with an FMU..usually either pig rich or lean never a halfway decent ratio. and in my friends case the car ran for two days and fouled out 3 sets of plugs before it wouldn't even start anymore. They're a crude way of just forcing more fuel through the injectors to run in a "safe"" af range..you'd be better off just leaving it with just adding some extra injectors on boost-triggered switches plumbed into the fuel line.

Re: why is fmu SSSSSOOOOOO shitty?
 

boots trigger switching extra injectors jb weld in charge pipe owns fmu's!!
ive done it..

use a few stock honda 240's

Re: why is fmu SSSSSOOOOOO shitty?
 

Fatty fuel pump, adjustable FPR (for turning down idle fuel pressure), FMU, fat return lines, injectors, and a BTM box for retard. Happy boosting!

Re: why is fmu SSSSSOOOOOO shitty?
 

:y


i ran fmu's on my first 4 turbo'ed civics never had a problem ever the first one ran fine for 2 years. 8psi daily and up to 12 at the track all i ever did was retard my timming at the dizzy


anybody who says they are unreliable and a headache is eather a retard or never used one.

Re: why is fmu SSSSSOOOOOO shitty?
 

The best part is everything but the cheapo $50-75 FMU can be used if you step up to a real management system. Scratch the BTM if you want since it's pricey and just do like bitchass said and turn the dizzy back.

Re: why is fmu SSSSSOOOOOO shitty?
 

THANK YOU!!!! youre the first person here to agree w/ the fmu. installed it tonite and finally got to beat on it!! this ---- pulls nice at 6psi. cant wait to get it tuned, but more focused on getting the d/p and w/g dump connected tthe exhaust. cant wait to run some fox bodies!!

Re: why is fmu SSSSSOOOOOO shitty?
 

RUN 9psi THEN YOU WILL BE REALLY HAPPY YOU WONT EVEN NEED A GIRLFRIEND

Re: why is fmu SSSSSOOOOOO shitty?
 

go on ebay and grab yourself a greddy rebic or sds eic. ive used both of those extra injector controllers without a problem and its more practical than an fmu

Re: why is fmu SSSSSOOOOOO shitty?
 

oh yea so when you have a intake back fire you can blow your manifold off and start a giant fire in your engine bay. totally better idea :y

Re: why is fmu SSSSSOOOOOO shitty?
 

i was lucky enough not to have a back fire when i used to use one.. 8)

Re: why is fmu SSSSSOOOOOO shitty?
 

you can say that for almost anything, but no problems for almost a year. i have had friends running them without problems as well.

Re: why is fmu SSSSSOOOOOO shitty?
 

word. all things considered, i think ill just stick w/ the fmu. itll only be a couple of weeks til i can get it dynod w/ bigger inj/f.pump. i can wait.

as for you, i guess thats where you and i differ. to me theres ABSOLUTELY NO substitute for -----. to each their own

Re: why is fmu SSSSSOOOOOO shitty?
 

enjoy your gay fmu :o :o :o :o :o :o and rice fuel pump

Re: why is fmu SSSSSOOOOOO shitty?
 

10.40's back in 1999


fmu
stock injectors
30 pounds
50 shot

Re: why is fmu SSSSSOOOOOO shitty?
 

high volume/pressure fuel pump and stock injectors exploding lol

Re: why is fmu SSSSSOOOOOO shitty?
 

more like car goes to first nhra quick 16 finals



took out eg berghonoltz in the semi-finals


fmu's work if you can figure out the trick >:D

Re: why is fmu SSSSSOOOOOO shitty?
 

go mother ------- hang yourself.

FMU's suck because people are double to tripling the stock honda power outputs you stupid fag. your average ECU VS injector size of ANYONE's make with more fuel pressure can handle 150-175% stock power output. Not 250-300% you dip fucker

Re: why is fmu SSSSSOOOOOO shitty?
 

we did it in 1999



car ran 10.40's
138 mph
2000 lb car do the math




Only done because back then you either had to have accel dfi or motec which were 2k+



Can it be done yes,maybe 3 people in the world now what was done to make it work and yes it worked and worked great. Open up turbo mag and find about 3 events the car made it to in the finals pumpin regulator sticker on the back LOL


Is anyone else doing it I guarntee no else will figure it out. Is a chipped ecu better any day of the week. Chipped ecu's are the way to go


fmu's are a thing of the past

Re: why is fmu SSSSSOOOOOO shitty?
 

ecu+ in conjunction ------ism wiht FMU like a low ratio one 2:1 so i can turn up the boost on my rap stinge mobile to 25 psi on 450's :6 :6 :6 :6 i got a supercharger fmu its like 2.3 ratio or some ----... im about to try that on my sohc vtec cuz my 450 get reall close to maxing out..@20 psi..

just like he said it can be done.. fmu is yes better than nothing just get some accord 290 cc injectors ( 8)poket item at pick n pull 8)) and throw them in with a gay fmu it will suck on fuel millage through kinda.. unless you get a adjustable fuel pressure regulator too and drop your base psi a little make sure the vac hose is off when your adjusting your fuel pressure and get a gauge so you can see what to adjust to..

update
if you just want to boost safley and have fun just leave out the FPR use fmu+290cc it should work perty well on stock fuel pump if your getting too much fuel under boost make a synchronization hole in the vac line going to the fmu to lower the pressure going to it so it will advance the fuel pressure less

Re: why is fmu SSSSSOOOOOO shitty?
 

had stock injectors
12.1 ratio
fmu


car ran pig rich figure that one out


car with the bottle according to basic hp calculators show around 450 whp

Re: why is fmu SSSSSOOOOOO shitty?
 

Fmu ftmfw if you on a tight budget. Retard timing at the dizzy and call it a day.
