I have a 11 gsr with the following mods.
Ets intake, inter cooler pipes upper and lower, Cobb down pipe, high flow cat, Cobb access port and Ivey tune.
I just opened my glove box for the hell of it to check out the air fuel gauge and boost gauge and decided to get on it a little and kept my eye on the gauge quickly to see what the air fuel gauge shows. All of a sudden I see it between 11 and 12 ?
I could swear maybe I'm wrong, but doesn't it have to be around 14 ?

Just a report:
I did get the p0017 code a week ago and my mechanic friend updated the computer with the new 2011 update and checked the timing belt and it was fine and did oil change and no more light.
Is it possible when I detuned it back to the accessprt, updated the computer and reloaded my tune again could have caused it to run lean.
Again am I running lean ?
Again when I floor it it stays between 11 and 12 the most and while idling around 14 and 15 and that's just idling.
Please someone help me out here.

 

lol no your running just fine. You want you Air/Fuel mixture to be around 11.5 under loads equaling over 100-120%. As far as your idle, your fine...detonation won't occur at 14-15 during idle. Enjoy your car and have fun man, start worrying when your Air/Fuel starts creeping up to 12 or higher during a WOT pull....

 

Lol thanks, for a second I thought everything became a mess
Thanks again.
Happy Holidays

 

Word of the wise, don't let friends touch your ECU once you're tuned...or at all. All you basically did was overwrite the changes each time, so in effect you made zero changes or updates to your ECU.

 

+1 to that man
