i went to get a custom dyno tune and before i was able to get on the dyno i was told we werent able to tune because my o2 sensor would not cycle.

what does this mean?

i have the bosch replacement o2 sensor. Can this be tuned

or do i need an oem o2 sensor. Does anyone have a part number for the oem o2 sensor the one in the o2 housing.

 

www.oxygensensors.com the same thing happenned to me when i went to get mine tune.... make sure you indicate which o2 sensor you want pre-cat or post-cat... and o2 sensor is good just make sure it is a pre-cat o2 sensor

 

will a 9 front o2 work on an 8

I thought the stock ones were bosch?

Yes, the sensors are the same, but have a different part #. I called oxygensensors.com and was told that Walker sensors are made by Denso and that they spoke to Walker about the differences between the '06 and '03-'05. Walker said they are the same sensor, says oxygensensors.com. I now run a '05 sensor on an '06 motor with no problems.
