WTF? YES! I am
better than you!

Default E-Manage maps...

I'm putting my stock EJ25 with the AVO kit back in the RS.

I'm dicting the Link 1 that came with it in favor for the E-Manage.

Any one have some basic maos they can e-mail me to get started?

BTW:
MY01 RS w/ AVO kit, E-Manage w/ MAP sensor, ignition and injectors harness, and 255 fuel pump. Stock injectors.

ANy help would be appreciated.

EJ257 is getting "Built" WRX heads and going into a black 03 WRX wagon with the GT30R and maybe the FMIC. I havn't decided how far I want to go with it yet.

The RS-T is gonna be my toy for now.

OT - I think I had enough of my Link, but I think I would probably spend the big bucks for an SM4

I went with the blue. A guy around here bought one for his turbo celica project but it really wan't working out with his VVT-i so he went AEM instead.

Blue, ignition harness, injector harness, map sensor, map harness, and tuning tool all for $450.

Tats the problem is that you really need bigger injectors, and that proves a problem with using the MAP sensor as load.

Not that I'm doubting you but if the link 1 can run the stock fuel system up to 7 psi of boost, why can't the E-Manage runt it up to 7psi with a 255l pump?

Is it something specific to the unit/map sensor?

Also...can stock RS injectors be modded like the WRX ones?

I would be impressed if you got 7psi boost to 11's afr with 100% on those stock injectors.

You for sure will be able to get 100% out of them with the emanage, but believe me you make alot more power at 7psi than can be supported by stock injectors even given the slight increase fuel pressuse from a 255.

at 7psi boost I need 90% of my wrx injectors to maintain low 11's afr. So hats off to ya! you can always put wrx injectors in there. People say it desn't work because the bosses are different, but if you stack some odd sized orings in there and block the air assist tubes coming in, it works fine. I put RC750's in a MY00 manifold. Took a little fileing till they fit snug but they sealed fine. Spray pattern might have been a little off but not too bad.

hmmm.....maybe i'll just drop to 5psi till i can find injectors.


MAybe a RRFPR will do it?

I don't seem to recall any plug and play injector upgrades for my01.

do you have a wideband?? any knock detection??

remember to take out tons of timing, your ecu runs up to 34 degrees up top.

I guess it all depends on the AFR you're targeting - I know I get beyond 100% IDC somewhere between 5psi-7psi, near torque peak (possibly soon after 3500). Stock injectors and fuel pump. The bigger concern is the timing since stock ECU have loads of advance, and I'm not sure the MAP and TPS signals can be manipulated enough to give a nice rich AFR on boost. Even a WRX has some sort of RRFPR

M'kay.....I have an LM-1 wide band....and some modded WRX (740cc) injectors in the mail. No 255 pump though. The local shop tried to rape me (197.00 for a walbro 255...yeah right!).

At 740cc I don't think I'll need it any way.

May by the end of next week I'll have time to install everything and start tuning.

And helpful hints for the emanage n00b?

KGB - question .... I am going to use the emanage to for an engine swap what do you mean when you say...? "The bigger concern is the timing since stock ECU have loads of advance, and I'm not sure the MAP and TPS signals can be manipulated enough to give a nice rich AFR on boost. Even a WRX has some sort of RRFPR"



RRFPR ... elaborate... on this please. When you speak of MAP and TPS signals are you saying the Emanage's range isn't wide enough to tune to a proper AFR under heavy boost? Even if its tune with a wideband installed?


What are you running in your setup?

its going to be difficult to tune out injectors that big with map correction. I would seriously trading up that blue emanage for an emanage ultimate if you are going with injectors that size.

I don't think you understand the reason that you need the fuel pump. Its not to increase the fuel pressure, its to increase the potential for higher fuel flow. Big injectors is not a reason to forgo the fuel pump but rather increases the need for one.

helpfull hinkts for the emanage newb:
pull tons of timing to start out. Like 1.5degrees / psi boost so at 5psi boost you should be seeing -7 or -8 degrees. You will ikely be able to run more, but give yourself the headroom for mistakes in your fuel basemap. Here is a datalog from a 02 RS which will give you an idea as to what your base timing is: Note: my car runs about 4 degrees more timing than this stock. I always thought that the phase 2 cars ran more timingm but the ecu logs down back it up.


Code:
(RPM) - Ignition Timing (BTDC)	- Manifold Relative Pressure (PSI)
2071	21	-5.804

5828	31	1.016
5952	30	1.161
6039	30	1.306
6117	31	1.596
note also that this car is running turbo with the wategate ties open, thats why you see slight boost there after 5k RPM

remember to be conservative. shoot to richen it up around 3500 and get to mid 10's and hold till readline. from there you can experiment with less fuel and more timing if you have knock detection.

I suspect you will need a pump other than stock, as well as a bigger FPR - the stock ones doesn't flow enough and without a pump to put up the pressure, you might not get the full 740cc flow.

jkjersey - the key is stock injectors + pump + FPR. With only MAP/TPS fiddling, you are still bounded by the stock fuel MAP. I'm not sure the blue e-Manage intercepts the injector signals as well - the PerfectPower didn't. From what I read here, the WRX might have a a RRFPR as well to help squeeze more fuel out of the injectors (might not be a big ratio one though).

Tats - pulling ignition should be fine

Mmmmkay.

740cc Injectors are here.
Walbro 255 is in mail.
O-ring kit from Sean @ Rallitek to fit WRX injectors in 99-02 manifold are in the mail.

Can't wait to get this going. Before I know it snow will be here making life way more difficult than it should be.

740cc injectors are huge for the emanage, I tried that setup on another piggyback system the Split Second FTC-1 and I was never able to tune the injectors down enough so the car wouldn't spit fuel out the exhaust
