Wideband logging different than display

[woodnbronze24]

To make a long story short, I just broke in my built motor and am now looking to start tuning. Doing some logs, I noticed that my aem analog wideband (in the ecmlink log) sits at 15.8 until I get on it. When the wideband responds in link, it reads almost 2 afrs leaner than what the gauge is displaying. The gauge itself seems to operate smoothly and leads me to believe that the gauge reading is accurate. The sensor is located the appropriate distance down from the manifold as stated in the instructions and I have no exhaust leaks. Any ideas? I'll attach a few logs to show whats going on.

What version of Link are you running?

In V3, there are about 4 different AEM options. I have to mess around with them until I found one that read close enough to the gauge's reading. Found (after a suggestion from a member here) that the one called "R1" got the closest.

Try the AEM R1 WBO2 setting. That is what I had to use since mine was logging so lean on the regular AEM choice.

Great. I'll try that.

Try the AEM R1 WBO2 setting. That is what I had to use since mine was logging so lean on the regular AEM choice.

Just tried all of the aem widebands and no dice.... The R1 reads 19:1 at idle and does not move. Am I missing something? Do I need to ground the black wire on the rear o2 harness that came from the stock sensor?
