This is interesting. I've never taken a look at flex fuel ROMs / hardware implementations as they were generally catered for E85 which we don't have here, but the fact that it can be used to 'switch' between two states is particularly compelling - I'll take a further look.

I suppose it could also be used for multiple timing maps, with a switch to deliver fixed voltages (0V, 3V, 5V for example), but if I understand the implementation correctly the second setting would only reside between the E0 and E85 value range?

yes it you input a voltage to the evap to simulate a flex kit you can have multiple maps
