v3 WOT tune, 25%+ fuel sliders

[BrokenTsi]

I just got done with a new build, and I got my cruise and idle fuel trims tuned pretty decent.

I did a quick 3rd gear pull at ~12psi and I noticed my AFR's are in the 13's. So kept adding fuel on the fuel sliders until my AFR was in the mid low 11's range.

Here are a few mods that will help:

bosch 044
1150cc injectors
-8an lines
3" uicp
q45tb
base fuel pressure 37psi
GM alternator, 14.0v at idle
bw s366 t4

I will post the log in a few minutes.

It appears that I can't take my log from the dsm link forums and post it on here.

Basically, my global is -61.3, or -60.9 and my dead time is 570. Should I be adjusting my global? Will changing my global from say -61 to -55 pull my AFR down? Won't I have to redo all my idle adjustments, or will it not affect idle and cruise at all......?

Are'nt 11s kind of rich, I'm new to tuning.

No. I like to tune to 11.1-11.3 which is deal.

Not under WOT (wide open throttle)


OP your global is currently correct if your fuel pressure is 43.5, the fuel pressure the injectors were rated at. I would change it to 43.5, and yes you'll have to re-tune idle and cruise.


Even so that doesn't explain why you have to add 25%

Then I suppose the fuel pressure is the culprit. Its currently set at 37psi, which is stock. I could either adjust the global, or raise the fuel pressure. What do you think? Changing my idle tune isnt a big deal, thats easy. I'm switching over to SD as soon as I can get things to act accordingly.

Not sure if you realize it, but you still have your open loop threshold settings pretty high. I dunno if that makes a difference with WOT tuning at all. I"m pretty new at it as well.

I cant review the log at work because its on my other laptop. I logged closed loop, does it switch from 1 to 0 during the pull? or vise versa, I forget. I set it up to switch over after 65% throttle.
