Will the E-10 setting/function I just noticed when I updated
my PV be of any benefit ?
I noticed2-3 options, gas,E-10 and E-85.

Unlike AFR, a Lambda is absolute. The toggle for gasoline, E-10 & E-85 allows you to select the AFR representation based on the stoichiometry for each given fuel. For example to find AFR for E-10 at a measured .98 Lambda you would use the following equation: .98 X 14.13= 13.84 AFR.

Changing this dropdown does not change the tune in any way, it simply changes how AFR is represented.
