no. for some reason the ECM calc'd out that much fuel being needed(pressure spike?). the ECM itself doesn't know or even care about injector DC, just how long the pulse needs to be.

Yea thats what I was thinking. 250Hp sounds obtainable. I really didnt think that Id hit that kind of number so soon, or I would have gotten larger injectors. I got a really good deal on these GN ones.
TPIS had some adjustable regulaters in there listings on eBay I remember. If your borderline could you just raise presure a bit?
Then again that little blip could be running out of fuel. A new fuel filter could be in order to start. Or it may be time for a little bigger fuel pump?
The fuel pump/filter and basically all the fuel componets including the lines were replaced about 1 year ago. Yea a bigger pump would definitly help. I logged this today and not hicups really so im not sure whats up with that issue.
Can you guys check this file/log out please? I ordered the file by injector DC then the boost pressure. It looks ok/safe "i think" to just keep the boost there and hopefully the car doesnt lean out the hotter it gets outside or ill have to add fuel and lower boost till I get the fuling raised with new pump/injectors/exc.
Thanks!!!!
the hotter it gets, the less fuel you need, since a hotter airmass is less dense.
Duu.. i knew that.:mad1:
But under 85 % dc is safe correct? Thats about what I was pulling on that excel log.
85 is about the highest i would go.
some factory applications are actually worse, the northstar engines are a good example. they reach nearly 100% DC dead stock.
Well I broke something a few minuets ago. Heres what happendhttp://www.thirdgen.org/techboard/im...milies/mad.gif
I was crusing arround for a bit and wanted to do a WOT pull when I was coming back down my road.
Shifted out of 1st fine, then when at high rpms in 2nd gear, I felt that brick wall effect, and let off gas immediatly. Costed to the house and once in the driveway, afrs were leaner then normal @ idle and the car was shacky unless I gave it some gas.
I checked the plugs and were ok..thank god! I believe its a injecotor that is shot?? Or mabey thefuel pump is bad but i can not check pressure at the moment as I dont have a fuel pressure tester. Gas will shot out of the shreader valve but you all know thats no way to test gass pressure.
I attatched the log from the incident, as you can see I was doing fine untill the AFR went high and I let off fast. I felt the car as if it was hitting a brick wall.
Car still runs/at least enough to move...LOL.. but i need to attend to this fast as the races start in 3 weeks and now im back to tearing the car down again... crap!!
can you check compression?
I did... its good. Same 145-155psi in all cylinders. Afr is now 17-18:1 at idle compared to the 14:1 I had it set at before. I will ohm injectors out tommorow. And then fuel test, also pull a valve cover and take a peak. Any other sugestions??? Thanks man!
Ill go and test the inject. tommrow and do some trouble shooting but if it is a injector. How good are gm ecm's at controling the ms pause of the injector. Can i go 42lbs or so and still be able to control the idle?? Or should i go 36.6lbs?? This is IF the injectors are actually the problem.
that ECM is capable of controlling injectors down to resolutions of ~0.0152 mSec...
also, a question comes to mind: are these hiw or low impedance injectors? and did you run them as high or low impedance?
There hi z injectors. And I used the $59 code as high z injectrors.
