going KA-T w/ E-manage

Post by **PapaSmurf2k3** » Tue Apr 27, 2004 4:42 pm

Ok, I know you guys get these posts all the time, but i searched and this is one of those things i want to be 100% sure on.Im turboing my 91 KA with a 2002 subaru WRX turbo and 2002 WRX intercooler (being converted to front mount). I already ordered the manifold from JGS tools, and have already bought the gaskets and fuel pump. here are my few questions: Do I need a fuel pressure regulator? Are there any nice websites to find 370cc injectors cheep (none on ebay for cheep right now). For the greddy e-manage, do I need everything (injector harnesses, and support tool?) and after I get the e-manage, will I still need a boost controller, or will the e-manage be able to control that? I have a laptop to program, so that is no problem. All the piping is going to be custom from a friend of mine's shop. Is there anything else I need? Thanks a lot.

there was a guy selling 4 sr 370 injectors for 100 in the classifieds,

edit. nevermind they've been sold

you can usually find them on ebay for that price though

nope

you will need the support tool, since you have a laptop, the other harnesses are optional, I will however recommend an ignition hardness, so you could control the timing.

and after I get the e-manage, will I still need a boost controller, or will the e-manage be able to control that? I have a laptop to program, so that is no problem.

the e-manage can't control the boost, so you will need a boost controler

Cthunder: " actually you do need an FMU, the emanage cannot ADD fuel when you boost more. the FMU will add fuel in a 12:1, 10:1, 8:1 or even a 1:1 ratio to boost. you WILL run lean at top end if you do not run an FMU. the Emanage CONTROLS fuel while the FMU ADDS fuel."

That is incorrect, When you richen/lean the mixture you are adding/reducing fuel.

Controlling vs. adding…what rubbish

In a different post he responded to this comment

sx7r --- “my point is the E-manage adds fuel by altering injector pulse width. end of story.”

Cthunder---- “no, it sends out a signal to add fuel... the injectors attempt to add fuel. if you're maxing out your injectors, most likely your entire fuel system is maxed out too. this makes the e-manage fallible. it's not a good system to rely upon if you negate your fuel upgrades along with an e-manage, this is what I've been trying to say all along.”

Oh so now the e-mange adds fuel…:rolleyes I see:rolleyes …this guy is a classic

An FMU is not needed to run an E-Manage. Cthunder has no idea what he is talking about. I have been running an E-Manage on my KA for more than a year with no problems. I removed my FMU when I installed the E-Manage. I will correct him in that forum as soon as my account is activated.

I wouldn't even bother... as it was posted on the other forum that guy just needs to have the last word

He does have a point... very hidden in all the rubbish he is saying... IF your injectors are maxed out then of course attempting to go past 100% duty cycle won't work (hell going past 85-90% duty cycle won't work). So an FMU will add MORE fuel. But as has been discussed before I wouldn't do that with anything bigger than say 370cc injectors, preferably 270cc at most.

c-kwik you even removed your factory FMU?

see this is something that I was wondering about... I have 50# injectors and I plan to boost something around 15-20lbs- I think I'm gonna end up maxing out before I get all the way up there. ...But you're even taking off your stock FMU? Whats the fuel pressure like if you dont have that on??

Post by **huguetpj** » Tue Apr 27, 2004 4:42 pm

I'm pretty sure he DIDN't take it off... fuel pressure at the rail would be... hmmm about 1-2PSI tops depending on line backpressure

I agreed , C-kwik there are no point to talk to him, let him be with his FMU+ JWT + SAFC +720cc . JWT never met to use with FMU , there are no need for a FMU, period. that dudde like to brought it up because he thinks he knows everything. I just want to prove that the newer model Altima can be turbo because they are the same Ka like any other one , I don't mind if JWT dont' make anything for it, but there're other alternative to manage the fuel system.

FMU = Fuel Management Unit. Which is some kind of a fancy term used to describe a rising rate fuel pressure regulator or a boost dependent fuel pressure regulator. The stock FPR is not a rising rate unit. The rate stays constant(1:1). And I do not recommend running without a stock or aftermarket 1:1 regulator. The FPR keeps the fuel pressure constant relative to manifold pressure. At low boost pressures it will still probably run, but will limit how much fuel can be injected if you do not have an FPR. At higher boost pressures, it will likely start to both seriously affect flow, but also may cause the spray pattern to weaken and become inconsistent.

Thanks for all the help. What kind of boost controller do you guys reccomend? I was thinking greddy profec B. Is that all that hard to wire in, and do I need anything else? im planning on running around 8psi.

if u want to spend little more, i would suggest u to get a E-01 w/ boost controller, then u don't need a laptop , no need to buy the 100 bucks cable / software . that may save u little more

Well, I just finished posting there. We'll see how he responds. This should be fun.

Well, Im trying to get this deal for an emanage that is being sold with all tools harnesses etc. but if that falls through, ill look into that other boost controller. By the way, is there anyone in the new england area that has some serious turbo know-how that might wanna help me with all the tuning and general crap that goes with all this? *wink wink* fiznat *cough cough* heheh. Im in southern RI. Thanks again.
