I currently have a Aem wideband and after tuning my car yesterday it was reading way richer compared to the wideband for the dyno pack. The dyno packs wideband was reading 12.1 and 12.2's why my aem was reading 10.8 10.7's so I'm wondering what everyone is using and what would you recommend. I know everyone is gonna have there own preferences but would like to hear what you guys are using and what you have had luck with in your builds thanks.

Thanks for your input. Very much appreciated

 

Where was the dyno pack wideband installed compared to the AEM?

 

It was maybe a foot to a foot and a half away. Where is the best place for the o2 sensor to be located for the most accurate readings...

 

The closer the better however the closer you get the hotter the O2 sensor will also get which will decrease the life of the sensor. Typically you want it around 18" away from a turbo(with a standard O2 sensor bung). Was the dyno wideband just stuck in the end of a tailpipe or dump tube? Was it actually installed into a bung? Was there any flanges in between the AEM and the dyno wideband?

 

It was installed into a o2 bung and there was one flange in between..

 

Are you sure you did not have an exhaust leak before the dyno O2 sensor? That will definately throw off the readings. If you can get it back on the dyno I would swap the two sensors position and see if anything changes.

 

Everything was and is tight...positive on that..

 

Since it is most likely not on the dyno anymore pull the O2 sensor and check it to make sure it isnt covered in oil or dirty. Try installing the sensor in the sencond bung and see what the numbers do.

 

Ok thanks for the info appreciate that...
