if you going to use the EU to scale the injectors, then leave the fp at 34psi at idle. Are you adjusting the fpr with the vacuum line off or on the fpr? It should be off and adjusted to 34psi then connect vacuum line to the fpr. You will have to play with the duration.

 

well i left the vacuum line hooked up when i adjusted it..

i thought thats how you do it...

regardless im giving up on these injectors...im putting my DEK's back in there and hoping i can just run these till i get my 440s tested...i really think the injectors are stuck open or something crazy....they are brand new from DW...but im done with this $hit...its been 4 FULL days of me dealing with this...and ive gone thru 15 gallons of gas just idleing in my garage...gas is everywhere...and i think im going to go throw up now from the fumes hahaa

 

Change your oil too !!!

If your injectors are in fact "stuck open" then thats alot of gas seeping down past your pistons into your oil. Gas is not a good thing for your main bearings.

Didnt you get a test sheet with your New injectors ?

-matt

 

well they did come with all the documentation....they were suposed to go on my friends max (he bought them new) but i got them offa him...he is gona mail me the flow charts and all that...wut exactly do you mean by test sheet? there is a way to test them yourself?

 

I don't think lag time has anything to do with the duration. With scaling you should be able to lean out the car.

 

This happened to me after I installed my spacer on my Z. The car ran real bad and I had gas spewing out of my tailpipes.

 

The air filter is NOT staying there...this was just to get me home from the muffler shop..

Stock injectors are in (FP set at 4bar) i gave up on the 440s they are being sent back to DW to get tested...

boosting at 9 psi with a 10 pound spring...only 1 psi loss? hmm....good i guess for a RMT?

other pics of gauges coming soon after i install em tonight

 

man i love how u ran you're pipin along the outside of the rails. When I first started thinkin of doing RMT, I was set to do it there for the slightly better ground clearance.... then I actually got under the car and remembered that I have SFCs that are welded along there, LOL. So I had to run it on the inside.

WRAP THAT YPIPE (HEADERS IF POSSIBLE, so far i've only wrapped the front, havent gotten around to wrap the rear headers yet) AND B-PIPE ALL THE WAY TO THE TURBO!

You think its fun now? WRAP IT, I promise the pink slip of my car, it'll be a completely different car! Instant spool, more power for daily driving, at least 400rpm earlier spooling... it will be sick, DO IT!

 

Yea i bought a 100ft roll of exhuast rap at some store here..

if i have time tonight im gona do it..

i also have to put my RSB on...that i for some reason waited 2 years to actually get? lol...

yea i was looking and with the pipe on the outside i think i can still manage somehow to run the SFC's cause i plan on doing that some were down the road...eh...i got plenty of other things to worry bout now tho lol...

as soon as i finish the interior and wash the max ima get a video and more pics for you guys..

and im getting rid of the black tubing...too much turbulence...ima c if i can figure out some kind of 3" mandrel bent piping to replace it somwhere...dunno where..but ill figure it out later...

oh yea and wut i find kind of odd...is the fact that i havent had to really make ANY fuel adjustments on the EU with the 9psi i have...kinda wierd? i really hear no knoc but i havent really done a good data log yet...ill have to check it out tonight or tomarow..but its pulling hard and strong...right before redline (bout 6k or so) i lean out to bout 12.5...thats about as bad as it gets running DEK injectors at 4bar....

 

Definitely check the injectors. When I first went to 370's, I had a leaky injector and it caused symptoms like you're describing.

Also, when I went to 660cc's, I had to turn the fuel pressure down to like 26psi with the SARD AFPR. Even then, the car ran rich. Standing behind the car all you smelled was gas. But I had no cats which didn't help. A few times, my car even shot fireballs out of the exhaust when we were tuning. But surprisingly, my gas mileage was just fine. Oh and I had the Z32 MAF.

 

I have the exact same problem with my 450cc/min injectors and my emanage ulitmate. I tried very thing, lag time duration, fuel pressure, Nothing. I am still just as stumped as you. The strange thing is i was able to tune and drive for two days befor it started acting weird, (pig rich) and after that it has been all down hill. Let me know if anything workes for anyone.

 

yea well im sending them out probly this week or next...

as far as the boost, i just realized i must have been looking at the gauge wrong or something...cause after the baffled muffler and redesigned piping i noticed im only boosint about 7 psi...

so about a 3psi pressure drop...much more realistic...i still have to use the exhaust wrap i bought...and fix a few minor things...

hopefully a dyno will happen next month....im gona pull some data logs tonight...

 

Its funny you mention that about the muffler. When I first installed my muffler, I went from 8-8.5psi to 6psi. Stayed like that for about a week. Slowly... boost started going to normal, WITH the muffler... (wtf? maybe the muffler needed to break-in? ). Now as proven from my last dyno, The muffler does indeed restrict flow, and yes it does take a toll on power. However, for months now I've been making the same PSI with or without the muffler (cutout open/closed), its just that the restriction does take a toll on power. But I do achieve the same PSI. Give it some time I guess, lol.

yes!!!! wrapping will make a difference. I gained about 1psi from just wrapping the b-pipe without touching the boost controller, lol.

 

trudat, you do achieve the same psi with muffler on but ofcourse power is not the same, interesting stuff.

 

You know it might be that i was just trippin when i first got this thing running...

This is my first time with boost, and i kinda underestimated the fact of having to pay attention to so many more things (boost/AF/RPM)..as well as EGT...so maybe i am still boosting the same...i just didnt really realize it since i was still getting used to having to pay so much attention to extra $hit lol...over the past 4 days or so of driving it finally im more familiar with whats goin on haha

Im still learning the variables lol...maybe that comes also with my lack of tunning but i mean its very inconsistent as far as power when i do a boost run sometimes...sometimes its ***** the wall difference...and sometimes im like wtf? haha

hopefully if it cools down later today i will get the energy to wrap the exhaust and fix my damn oil leak (check valve to the turbo) maybe spend some time actually data logging a good run...i guess ive been pretty dumb just driving this thing with such little time tuning...but its running safe from everything ive seen....

 

Yea its alot of variables involved lol

Well keep in mind, the hotter the exh temp gettin into the turbo, the better it works. Being RMT that is our main problem... up until we wrap it, lol. Once wrapped, one 3rd gear pull after warming up to operating temp and its good to go!

Any updates from the beast-in-the-making?

 

the power not being consistent is most likely what was stated, the piping not being wrapped, notice how after you flooor it a few times, the more u run the car the faster it feels. cuz pipes get hotter, yet when it cools down and u floor it, it feels slow again.

driving the car gets some getting used to, even on an auto it took me time to get used to it. but now i have mastered it.

 

wow these RMT are sprounting up like crazy! Interesting way of running the piping (cold side).

I'm curious to hear of the results after you wrap the piping and see the results. I never imagined there would be that much of a temperature difference with it wrapped or not, and create a better flow.

this really seems like a good, cost effective way to get boost

 

All the fires out here and hot weather have not made it real comfortable to do anything other than sit inside lol...but i plan on wrapping the exhuast and spending a little more time tuning...maybe turn down the fp...cause im running fairly rich...i think i can turn it down a bit and tune from there...

Im getting a clunking sound right now from my piping under the tranny i believe...so i have to take a look at that and fix it...very minor problem...

Other than that im just having fun with it for the meentime till my next check...then LAIC and dyno! maybe turn up the boost some
