you may need to tweak the tables for e% vs voltage if their are differences in sensor calibration most kits put out 0 to 5v.

you can also just switch the evap inut from earth to open circuit as the ecu has an internall pull up resistor to 5v, this give you basicly e85 to petrol map switching on the fly no reflash needed and cost you $5 for a switch.
That seems strange, how does the ecu read accurate values from the sensor if the pin is pulled up? I can see pulling it to ground with a switch, but if the kit is just supplying a voltage, wouldn't the pull up cause it to read 5v all the time?
