Just verifying before i install FMU

[Matthew]

ok tell me if i have this correct

 

[Matthew]

come on people!

 

[Mr. Win]

i think i see what your doing

hahhah TTT

 

[LinuxRacr]

Dude, if you haven't already, maybe I can help with the location of some parts in the engine bay.

I can't really see in the picture, but doesn't it just tee off the vacuum line that runs from the pressure regulator to a solenoid on the intake manifold?

 

[Matthew]

this question is all i need answered.

charles - this is not a vacuum line this is a fuel line

 

[Matthew]

bump - am i right or what?

 

[Bigg Tim]

Don't you want to hook it up to the return line? Weather it's the feed or return, use one of the hoses that comes out of the hard line, back under the TB by the firewall. I used the one on the right side (drivers side) that went to the fuel rail to feed my extra injectors, so the other line must be the return.

It goes on the return line

 

[Little Beavis]

Doesn't look right. . .and you said the directions I sent you were unclear. . .

Looks like you're cutting the supply line, and as pointed out it goes on the return line.

 

[Matthew]

i dont know how i didnt see that...

 

[black_rob00]

Ok. This how it goes. The bottom goes to the return. I left my camera at work. These are old pics:

Pic#1 The top of the FMU goes to vaccum

Pic#2 The side of the FMU goes to the FPR.(the hose with the clamp in pic)

Exactly. Remember that the FMU works by putting backpressure on the return side of the fuel system, thus keeping more fuel available to the injectors.

alright, everything is good. here is where i ran into the problems:

1) the blue/pink wire setup on the ECU/volt clamp came undone, presumably when i was "flipping" the panel back over to re-install it
2) then the o2 signal wire came undone and was giving me a solid red light...that one was pretty easy to figure out once i got somewhere where i had a flashlight handy.
3) im having a hell of a time setting the mbc, it seems like i can only boost 4 and then all the sudden im up to 10+. i need to finesse it today, but i was just too tired to mess with it anymore last night, and was running out of patience...

Are you soldering the wires or just stripping them and twisting together? If not soldering, then you really should that way you don't have to worry about them coming apart.(thumb)

 

[Matthew]

i was using quick splices...

 

[Bigg Tim]

i was using quick splices...

Those are good enough for temporary use, IMO, but you should solder the connections to ensure they stay connected. I used those splices on radios before and after some time, I had all sorts of problems with them coming loose. It seems like you have already experienced some problems with them yourself. When you're all done and everything is finished and the car is running the way you want, then I suggest going back and soldering everything.
