What specifics are you looking for?

You realize that you already have an air fuel ratio gauge. That data is accessible in your computer but it never changes. The computer is programmed to maintain a constant 14.7:1 air/fuel ratio at all times.

yes, I do know that. Have been getting codes about the mixture though, so I would like to see what it is doing at all times. I just can not find the information for which wire on the computer that relays the information

Air/fuel ratio is a calculation, not a measurement. The computer calculates that.
