So Hal are you runing 355cc injectors ? Or did you just change the injector size on your standalone in order to fool the computer into runing leaner ? Why do you run a FMU with a stand alone ? What kinda stand alone are you runing ? Does it still have all the emissions controlls built in- like EVAP and missfire monitoring ? I'm currious as in IL they do readiness code testing and MIL testing, if the codes are not set or you have a check engine light then they fail ya.

He is running e-manage because I was see him on e-manage yahoo group. He has been asking a lot of questions lately. :hide:

So your running an FMU and 555's? Are you still on a single fuel pump? If so watch the fuel pressue it may drop off when you start cranking up the boost

So would it be a good idea to get a secondary inline pump also when you wanna crank it up per say

Nope, dual in tank Walbro

Have you done this? I am afraid of the higher fuel pressure running my walbro out of fuel at a lower hp... and couldnt think any easy way to drop in another walbro, but hadn't given it too much thought. If i run into this problem, I'll probably just go fuel cell w/ my old paxton/aeromotive 1000+hp pump

Cool!
 

What scan tool can I use on a 89 Maxima? Who makes it and approximate cost?
So the Warbo pump (like the GN's Have) works?
Factory Fuel pressure regulator or aftermarket?

Awsome setup.!!!!

The GS34X pump can support upto 720cc/min if you crank up the voltage to 16V: http://www.stealth316.com/2-fuelpumpguide.htm


It can support 550cc/min, if you upgrade the wiring and your charging system can provide 13.5V or more depending on your fuel pressure needs.

Nissan Consult. Seen them for on ebay for oh.. a few thousand. Your maxima is OBDI. This is before the Gov't mandated universal diagnostics for all automakers (all 1996+ automobiles are obdII compliant and can use obdII scan tools)

I've only seen a Consult-I on eBay, have you seen a Consult-II?

Let me know if you do.

Why would you want one?? I mean they are cool but not $$$$ cool!

Yes, but depends on the cards included and if you can download updates from the Nissanusa website or not.

I must have Hal mixed up with another Maxima.org member who is going to be or is runing a stand alone and gonna sell it for some .org memebers. Even with Emanage you should be able to ditch the FMU. I have a 240 with a KA runing 555s and TTZ MAF at 400WHP with no problem on stock ECU and Emanage- I just finished tuning it for my friend as no shops around this area know WTF they are doing with Nissans and cost him an engine.

400whp on a KA...damn.

Can you explain how you squeeze 400whp out of four 555s withOUT a FMU?

Even at 100% duty cycle and NA stringent 0.50 BSFC, that's not possible.:confused:

I run 4 bar of fuel pressure :) Nismo FPR with a Walbro in-tank, on Tomei 555cc injectors pulling air in via a Z32 TT MAF. You can get 300WHP from a set of 370ccs at 4 bar of fuel pressure. I do that daily with my G20 on a T25 turbo.

555cc@58psi --->640cc/min, which using again 100% DC and NA stringent 0.5 BSFC is good for 487bhp or 415whp assuming 15% drivetrain loss.

Alright, that's close, but damn close.;)

Okay I rounded off the 400WHP # :) its actually 387WHP, but its very close to 400WHP, and I'm sure if I where to get the turbo extrude honed it would hit 400WHP at that same boost :) I actually run 61psi on the KA and my SR. Works like a charm and the injectors have been happy for a long time now, no problems. Lets see 740cc injectors for 500 bux, or Nismo FPR for 90 bux... ehh I take the FPR :)

"400WHP" does sound better then "387HWP"....LOL.

Hmmn....61psi all the time and no leaks, fuel pump crap outs, etc....

Interesting...very interesting.

I am curious as to when you want your mevi open and when you want it closed. I went ahead and got rid of my VI. I finally got it to work using a check valve and vacuum canister, but dyno numbers show a drastic decrease in torque when VI is open as apposed to it being closed all the time.


It's interesting that you have had this problem. I have had this exact same problem, but was able to 'cure' it by shutting off the car for a few minutes. I thought it was my secondary fuel pump that was causing the problem. Since we don't have the same fuel setup, maybe its e-manage related...who knows.


Also, can I get a link to the e-manage forum spanishrice is referring to.

http://autos.groups.yahoo.com/group/emanage/

I played with it tonight, and the difference between a 4000 and 5000rpm changeover made 4mph diff. in the 1/4. Best I've found is around 5200ish to allow vacuum to it allowing it to open.

I doubt its emanage related, bc even when I connected the MAF back to stock (no emanage) and left all tables at 0 it was loading up extremely bad. I think my FMU is gone.

MUST PUT SPRAY BACK ON!!!
1.3 second respool on shifts, ahhhh

Nice....

Are those two spikes to ~13.1 on your AFR when you first go to WOT?

Is this at wide open throttle, what are the spikes from. I don't like those 13:1 or higher spikes, make my car go boom.

I've seen the afr do that during shifting.

would it do that in an automatic since the throttle plate does not close all the way?

those are when I lifted for the shift... then when I come back into it WOT, you see the 11.5 spike as it settles back into the 10s.

I guess I should have stated, the two flat lines are 3rd and 4th gear. and right before that, where it bounces from 12->10->12 is 2nd gear spinning like crazy as I tried to feather the gas.

I thought that at first, but figured it would go rich, since you have an open atomosphere BOV, ie metered air is released, so there is excess fuel.

I notice you say you went a little too rich. What AF are you trying to tune for?

I try for a steady 11.5

Ice, my MAF is after the BOV, so no metered air is released :)

I had it tuned to 11.8 (my goal) and tinkering plus a FP problem had me to 10.5 last night.
I think it is near 11.0 now

When will the turbo Y pipes be availible ??? I'm ready to do some nasty things to my new engine on the engine stand.

:shiner: :shiner: :shiner: :shiner:

jez, once youre done with the "new" dek, do you want to tinker with your ae vi and my de?

slimer, I got home yesterday and the dude revoked my bid- as I was the only bidder. Looks like every auction he had up was a fluke. It showed alot of diff engines for sale n stuff but nothing went through. But I am getting another DE-K so I can do some tinkering to it internally before I put it in the car.

aww thats bull****. Report him.
