I could not find this anywhere, and had to reach out to Glowshift tech support do get it, so I thought I would post it here. Here is their data logging reference chart.
AFR formula for E0 gasoline (V/0.5) + 10
AFR formula for lambda (V/7.42942) + 0.686
If you do the math, you will see these formulas are "close enough", They do not give the same result as what is listed on the chart.
