theres a few other things but fix those first its easier to take care of one issue at a time

actually before you do any of the recommendations that pengulns suggests...

either run WOT... or reconfigure your throttle because you never hit 99-100%. Another thing to look into before tweaking the fuel map as pengulns suggested, disable your O2 feedback, bump the entire fuel curves above 0Psig up a few clicks, and get an actual WOT fuel curve established first. then go back and reevaluate your O2 feedback map.

While it's a tad lean in a few areas...anything above 10-12 psi should be around 11.5-11.7... but that number could vary depending on a LOT of other conditions... so just start lower and work your way up... say... 11.0 and then lean it out a little at a time.

1.5K rpm stutter may be caused by running 'too' lean. try to add a bit more fuel at that range... actually a good rule of thumb for your scenario is to just bump up your entire fuel map a tad. and redo your O2 feedback fuel map.

i didnt notice he had O2 feedback on, yeah i never use that, in my opinion if you need it your maps not good enough and its really only for cruising... i dont think he ever tried to go WOT

[pacman3000gt]

yep... he has o2 feedback on.

I figured you just ignored the o2 feedback because it shouldn't be used for tuning anyways... but it's a good thing to use once you get everything tuned to counter drastic temperature changes -- off-boost of course.

I wasn't too sure bout his throttle... didn't know if he just hasn't configured it or if he hasn't gone WOT.

[pengulns2001]

id assume hasnt gone WOT since its never really stable, he has O2 feedback value in the logs but that doesnt neccesarily mean its on

[pacman3000gt]

hrm.. never tried to logg my o2feedback with it off... i guess I'll try it on the way home

If there are nonzero values in the O2 feedback corrections, O2 Feedback is enabled. They should be zero if turned off.

[pengulns2001]

didnt even look at the O2 feedback log... still havent but ill take your word for it lol

kinda lost at what you are referring to... are you saying that if there is anything in the o2 target map... it will log it?? or you saying that it is on i fyou enter any value other than 0 there? or are you referring to the o2 sensor FB window?

cause I have a checkbox that enables/disables the O2 feedback.

I was referring to that you can tell if a person has O2 Feedback enabled by looking at their logs if they are logging O2 Target Error. If there are any values in there that are not zero in the logs, then O2 FB is enabled.

Maybe I misunderstood what was being talked about. I don't have the AEM software on the laptop I'm on today so I can't see what's in the cal/logs. If he's using one of my maps as a base, it probably is doing O2 FB though.
