Air-Fuel Ratio Oxygen Sensor Ardupilot Setup and Logging

Has anyone here tried to set up an oxygen sensor (Air to fuel ratio sensor) to get real-time feedback on whether their engine is running rich or lean?

I would like to be able to stream this info through the Cube so I can more easily make carburetor adjustments.

I scoured the internet looking for any posts related to this concept, and I’ve come up with nothing.

Thank you!

AFR sensors not, but I have integrated various I2C and Serial sensors and devices with Ardupilot using Lua.
