Wideband install

accualy wait it should bottom out it 17:1 if it in free air, if it has been less then 6 hours since you turn off the car there is still some exhuast in the pipe and its reading that

Thanks guys, I got it all wired up but the long wire for the sensor is just rolled up in the engine bay for now. I need to borrow a jack so I can install the sensor.
I noticed the y-pipe that came with my headers already as an O2 bung right before the CAT so I am just going to put it in there as long as the plug is not rusted in there to bad.

Well got it all hooked up and my idle is going so lean it is maxing out the gauge.

that happen to me when ever i would flash the pcm.....

that can also be caused from exhuast leaks

Yea, I jumped the gun, as soon as the car warmed up it came down but is it normal for it to hover around 14.7 like .4 in each direction during idle and cruise.
Also will it read 14.7 as stoich evenif you change your comanded AFR. I Changed my commanded AFR to 13.5 just to be safe until I found out what the AFR actually is doing and it is still hovering around 14.7 eventhough my commanded is 13.5.

Where did you change the commanded AFR? There was another thread where someone was trying to change the closed loop AFR and couldn't find it in HP Tuners. I don't know about HP Tuners, but there are several different commanded AFR settings for different conditions.

If done correctly, and if handled correctly by HP Tuners, you should see the correct AFR that you commanded.

14.3 to 15.2 is a great range for idle and curis this mean you probly don't have any exuast leaks and your O2's are doing there job..... it will never be perfect

so what if you were running an open y-pipe and the WB was 5" from the opening of the y-pipe? would you see false lean then?

not as long as the car is on
