Thread: Am i running out of fuel?

Scan zz p from gtp4 -- Scan Depot dot net
Maybe maxing my injectors.(stock)
What u guys think?

it is very possible youre running out of fuel. youre running a 3.2 non-intercooled, which leads me to believe your next step is injectors..

however, what are your air temperatures down there? in the winter i get close to maxing my injectors out because of the cold air and it dumping more fuel in. i dont remember your scans from before, but i swear you were okay on the injector front a little while ago. your IATs are reading in the low 20s, is that correct? the cold air is causing your car to use more fuel then. it's maxing them out from the cold air.

time to start looking for some 42.5# err..

Let's do the math on frame 306. You're running at 6207 RPM; 6207/60(seconds per minute) = 103.45; 1000(milliseconds per second)/103.45(rotations per second) = 9.6665 ms per rotation. Your intake valve is opened once every other rotation, so 9.6665*2= 19.333 ms between intake strokes. You are commanding a 20.56 ms IPW and that's not even counting dead time, so yeah, I'd say it's time to upgrade.
