Talking with AEM over email,

It's come down to my issue being a bad gauge. The calculation is o2 voltage x2 + 10. So 2.3 volts x2 = 4.6 + 10 = 14.6 afr. My laptop is reading correctly and the gauge went haywire internally. Not what I would have expected. I asked about compatibility because the AEM Series 2 only lists older model widebands in the Wizard, the 30-4100 with Bosch 4.2 LSU sensor is compatible with the newer 30-4110 with Bosch 4.9 LSU sensor.

I just need to verify this with a new o2 sensor/gauge kit. I asked him if any deals going on now, none. I asked if amazon a reputable dealer, could be. I ordered one on Amazon.ca then cancelled, for whatever reason it lists AEM as a company from Miami Florida, that's false. This is a commonly counterfeit gauge, if you read the reviews so many have faulty sensors. So I cancelled the Amazon order and will buy one locally as soon as I'm allowed to leave the property.
