another 370cc injectors post.

[boost infested]

well, i finally got the lm-1 to work in my car tonight. Super 57 t04e trim with .63 and stage 3 exhaust wheel i was able to max the 370s out with only 4psi. is that about right?!?!

100% duty cycle, and its lean still. my a/f on the lm-1 is at 14.0-15.0, wot egt@1400-1450f. thats lean!

how do some of you guys run 7-10psi of boost with the 370s? how small is the turbo?

looks like i have to finish up my aluminum fuel rail and put in my 550cc this weekend.

something doesnt seem right with that. i thought the stockers could take 4 or 5 psi before 100%, and the 370's would carry to 8? might want to check your fuel pressure. what pump are you running?

alrite well the pump should be solid then. i would definately try to check the fuel pressure though, maybe fpr is goin?are you using e-manage/s-afc or a retune?

[boost infested]

emanage.

Are you absolutely sure you got 370cc because they sound allot like stock 270cc’s which max out at exactly 4-5psi.In the e-manage did you plot the old and new injector size?

yes i did. 270cc to 370cc(purple)

it is clear that you are running lean, and the injectors shouldn't be a problem.

The thing that comes to mind will be your boost gauge is not working properly, a leak in the line...

can you describe how you control boost, what wastegate/spring/Vacuum lines...

Another thing, do you have a fuel pressure gauges? If not, get one!Perhaps you have a restriction in the fuel lines, clogged fuel filter, clogged injectors…

tial 4.5psi spring. my boost gauge is show 4.5psi.

new fuel filter. i will try to get a fuel pressure gauge on there.

Well doesn’t leave too many options…Either its your wiring…which is unlikely

Or the e-manage unit not functioning correctly…try to mess around with the fuel map…add like 20-30% more fuel see if things change…

Man…this is really strange...

what happened to virus77's posts?

So i decided to reset the emanage by giving the main unit a new profile, and i am still not able to adjust the fuel map. The A/F still showing 14.8ish no matter what did to the fuel map. But i did get my A/F down to 11.5-12 by changing 270cc to 300cc. i figure the smaller the number you input the richer it gets through out the whole factory fuel curve. Now i have to go check on my wiring from my emange to the ecu.

now this is what mine looks like

[virus77]

your missing the injector groud, it is seperete from the main unit ground, and what happened to my posts

[boost infested]

the injector ground is the one below #4 correct?

[Aaron_9349]

Yes, the injector ground is directly below inj. 4. I think its a B/R wire.
