Lambda of 0.50 to 1.50 is a difference of 1.0 divided by 256 = 0.00390625

Lambda .50 to 1.50 volts with 1.0 being Lambda. Conversion: X * 0.00390625 + 0.500000

I sanity check by having three values for same data, one AFR, two WB voltage and three Lambda. At 2.5 volts should be 1.0 Lambda and 14.7 or 14.1 AFR depending on your WB controller if it can be set to anything but 14.7 AFR.

Some WB controllers can not be adjusted, so 14.7 is Stoich. Narrow band O2 sensor adjusts to Stoich, so Lambda is always correct.
So to repeat my question, what would the .adx conversion line be for a math challenged individual to display lambda vs. AFR?
X * 0.00390625 + 0.500000 ???
