Anyone good at tuning for emissions test?

Dave that's the same gauge I'm using. I'm wondering if my output ground is what is messing it up. Because the gauge itself is reading correct but it really if ever will go below 15 in the log. I set desired AFR really low today on the way home from work, just to make sure. And again it rarely reads below 15. I logged the trip home with the same adx you posted, so ill put that here. Ive 2x and triple checked that the bin settings are exactly the way the notes described. I'm going to go check wires right now now and maybe try a different ground for the output. I also borrowed a fuel pressure gauge, so Ill verify that in the morning. Ill report back if I figure anything out

So I moved the output ground from an engine ground to a sensor ground and nothing changed. Here is a short log and current bin, along with a pic showing the differences. It's like this all the time. I'm running out of ideas
