can anybody here show me a diagram with piks on how to install a vortech fmu!!??...tryed searching already

Honestly man... For the price of an FMU, you can use AFC hack, or what not. Personally, I'm a toyota guy so I went with Megasquirt, only cost me 160.

hahaha.. awesome instructions.
Honestley, I dont think anyone here will be able to answer your question. Try honda-tech.

We can answer but your better off doing it right your ring lands will thank you later ;)

have any of u guys ever had a fmu blow up ur motor? if so at what psi where u running? what fuel where u running? what was ur timming set at?

with an FMU i wouldnt go pass 7 or 8 psi. I was always

told that. Im running Uberdata, so i dont have to

worry.

it's less about the amount of boost your running and more about the fuel pressure you run... 11:1 FMU + 8psi = 88 fuel psi... 12psi = 132 fuel psi... thats just INSANE

as you increase the pressure of the system your pump flows less, you also at some point won't acculy get any more fuel out of the injectors...

there are ways around the insane fuel pressures... namely installing larger injectors and then with the static FRP drop down the pressure to the line so its getting a similar amount of fuel as it was before w/ the smaller injectors at the higher pressure... with doing this you can drop the rate of the FMU... it's old school... the neon guys love this method for some reason...

but why bother when you have so many inexpensive options at hand like mentioned before...

not saying an FMU and decent boost can't be done... i'm just saying there are easier ways to get at it (static FPR = 100$ + larger injectors (cleaned) $100 (will prob need this w/ the other methods also though) and then the FMU which can range from 50 to $450 depending on what you get that gets you a megasquirt n jolt system easily :)... or the AFC hack or... or... or...

What are you using for timing?

and now for the awnser,

the top plug is for fuel in, and the bottom is fuel out, run the fuel line from the fuel rail into the top port on the fmu, and run the return line from the bottom port.

Run a vacuum off the fpr

send your ecu to projekteg for chipping with uberdata. it will cost about the same, and it will work 100X's better.

it was, but you left out the description, from that pic you cant tell that the fuel going in is the port that is higher than the fuel going out.

Well, for right now I'm using an MSD BTM, haven't quite figured out how to hook up a toyota dizzy for Megasquirt'n'spark. I will possibly switch over to the Ford EDIS system, but the BTM is fine for my 8 psi I'm running now, I'm only retarding it like 8 degrees, no knock, everything is fine.

toyota distributor? isnt that an oxymoron? ;)

... what was ment by that....?
