FMU + FPR Question
 

ive got FMU 12:1 + missing link + T3
comming up: IC, charge pipes external WG @ 6psi, oil shizzle.

Do i need a FPR? or is a better fuelpump good enough? (dunno what fuel pump)

2nd Q

what happends if i have a fuelpump supplies more fuel, do i run rich @ no boost?
thanx

Re: FMU + FPR Question
 

with a bigger fuel pump your gonna run just a little rich at no boost but not too rich. you should ditch the fmu and get a vafc and dsm 450s

Re: FMU + FPR Question
 

.
if he's gonna spend any xtra money on anything it should be a chipped ecu.

Re: FMU + FPR Question
 

ive already got the fmu + missing link for cheapy 180 euro (netherlands) lucky me
chipping is about 500+ euro so no option for me. if i could chip my self i would, but pmgfi.org is to complicated for me.

so im sticking with the stupid FMU,

is it really needed to have a bigger fuel pump?
howmuch does the stock pumps? howmuch do i need?

what about another fpr? not needed?

D16z2 SOHC 1.6

Re: FMU + FPR Question
 

Yes a bigger fuel pump will probably be needed to supply the high pressure that the fmu will be creating. And no, you will not need a separate fpr. Your fmu is an fpr, just one that is dependent upon boost.

Re: FMU + FPR Question
 

damn, 80 bux US is 500+ in euro? im savin up n movin there lol. ill be rich biatch

man it cost about 90 tops and with a chipped ecu u dont need to upgrade ur fpr or fuel pump. just the injectors which u could prolly have enough money if u sell what u have.

Re: FMU + FPR Question
 

yeah tuning in the netherlands sux bigtime, 1st of all there is no lots of tuning, its kinda starting here, most of the ppl have k&n filters an nice muflers, and thats it or some light weight flywheels or in some exceptions preformance cams, chippin is so damn expensive. damn 90 bux, what do they dow ? ill give you 150 if you come over here and chip my ecu :) its probably only a base map? or dyno tuned? 1 dyno run is abou 45 bux or unlimited for 1 hour 200 orso. and then the crap begins..

back ontopic.

so ill be needing a fuelpump. what would yall recommend? heres my setup
D16z2
T3 12psi
FMU 12:1
missing link
IC
charge pipes
Oil stuff
equal length manifold (gonna design 1 my self) ill post pix when im starting this.
ext wg @ 6psi or less
98 octane fuel


what kind of a fuel pump do i need? can i buy it @ my local honda dealer/store like a interga pump? or a crv pump?
or just an aftermarket?

thanx for the replies

Re: FMU + FPR Question
 

fmu +fpr= KABOOM

Re: FMU + FPR Question
 

did anyone else catch this? a t3 at 12psi then ext wg at 6psi? pick one buddy lol...

get an inline fuel pump when using the fmu.

if you chip ur ecu its with a basemap which is better then a fmu. i drove on a basemap for over a year. it costed me 80 bux + shipping. thats it... no need to pay anyone to come over n do it for u, jus send it out, get it done, they send it back, ta da... if u chip ur ecu spend money on injectors instead of fuel pump.

Re: FMU + FPR Question
 

the internal wg is set @ 12 psi and that is to much boost 4me.
so im using an external wg @ 6psi max.. this is because the internal wg is not adjustable, + i have more faith in an external wg + it looks nice

mayB chippin'is a better option afther all. but running on a basemap, is still crappy, and probably i can figuer it out my self to put a basemap on my ecu with an eprom. running on a basemap still isnt the best there is. ill probably chip my next car/ecu when im going to buy a newer car.

i have an spare ECU from a CRX 88 PM7-B020. i never triend using it in my civic 1.6 SOHC D16z2, it probably fit or go well.
this ecu is hard to chip. and that sux. i do have software to make the binfiles and stuff. but i dont have a burner
and a dyno, and no WB O2 sensor an cables to the laptop.

ill buy a fuelpump. whats the difference between an inline pump and a fuel pump? (my english isnt that good)

what fuelpump is recommend?

Re: FMU + FPR Question
 

255 high pressure fuel pump...walbro
100 bucks(US)...im running with the fmu too
and it made a difference(from what
my wideband tells me)
i went from not even gunning the thing
to have safe ar(11:9-12:3) with the
fuel pump on 8psi.
going to chip the ecu though...with
injectors so not keeping the fmu for
long.

Re: FMU + FPR Question
 

for starters i know ur internal gate is set to 12. but u only wanna boost 6psi max. your gonna have to get the dp flange block-off n run the external wg only. you dont need both. i mean u could jus leave it there n not hook up the vacuum line hoping it stays shut. i had problems doing that over time, but it would work.

and if ur on the fmu long enough, you'll be chippin sooner then you think, not with a new car but with a nwe motor.

walbro intank or inline. doesn't matter i guess. use the intank, its always gonna be there.

Re: FMU + FPR Question
 

did you had FMU 12:1 and no fuelpump first?
what does gunning mean? 11:9 ?? i dont understand the 11:9-12:3

can i use a smaller pump than 225 walbro? something like a interga pump?
whats the difference between the stock civic pump an walbro? stock pumps 100? walbro 225?

@ turboDA6

i leave the internal wg closed there is a closed flange on it.

Re: FMU + FPR Question
 

i know that... its not a close flange, its the wg flapper. i had an issue with keeping it on, it opened under boost for me. then again im running way more boost then you.

the 11.9-12.3 is the air fuel ratio. those basically perfect ratios but i still wouldn't trust it on an fmu... a stock pump is stock. its only made to push fuel for the motor naturally aspirated. when u add air, u need to add fuel. so a bigger fuel pump is needed.

Re: FMU + FPR Question
 

ok i was a little conufsed by the 11:9 istead of the 11.9 thanx.

the walbro pumps 255lbs fuel
howmuch does a stock fuelpump pumps?
civic '90 1.6 sohc

ive seen on the internet some 190 lbs fuelpumps, is this also good enoug?

Re: FMU + FPR Question
 

a stock pump is old... dont rely on it. for the price dude, just grab a 255 walbro. its the best bang for the buck

Re: FMU + FPR Question
 

I just shipped a chipped ECU to the Netherlands...I've actually shipped a few now. I think its starting to pick up abroad.

Re: FMU + FPR Question
 

what was the total price of it? i mayb its a good idea for me to chip 2.

if ill buy the chip, what do i need for my setup?
6psi
255lbs fuelpump
stock injectors?

and the chip? (eprom?)

if i have chipped my ecu, can i then just add more boost? or do i need to re-chip, if i wanne run 8psi?

Re: FMU + FPR Question
 

you need some bigger ones, you can boostl ike 4psi on stock injectors but thats cuttin it close. dsm 450's are all over this site for like 50 bux

Re: FMU + FPR Question
 

ok so if im goin to chip then i need
450cc injectors
255lbs fuelpump
turbo, ic wg bov pipes, oil lines.
chip.

but i still dont have the awnser on my Q howmuch a stock fuelpump pumps. stock like 100 lbs? dunno? just guessing

Re: FMU + FPR Question
 

the stock fuel pump can flow a lot...but with bigger injectors.

with an FMU it increased the fuel pressure 12 psi for ever 1 psi of boost. so lets say at 10 psi, it will increase pressure by 120 psi, which is a lot.

Walbro pumps suck ass for FMU set ups because they do not flow well at high pressure. For you it would be better to get an inline fuel pump out of a drag or revhard kit and just use that.

Also don't listen to the people telling you to run a chipped ECU only. Chipping an ECU is the best way to go but only if you get it tuned by someone competant. FMU is way better than running on a basemap because for the 99% of the time you are not in boost, then you are running on stock everything as if you didn't even have a turbo.

One guy said he ran for a year on a basemap. Well there are about 234234 people who have run for a lot longer on an FMU and had 0 problems, just make sure you have a good fuel pump...that's the key.
