Evo 7-9 factory ecu mods to run flex fuel

has anyone successfully used the standard ecu to run flex fuel by using a ethonal sensor and a converter box to convert the digital signal to analog signal and wire it to the map switch input into the ecu loom?

iv so far got freefuel and tephra v7 iv got a bench loom setup and a fuel pump with a zetronix sensor and converter box with a jar of 98ron and e85 im having troubles getting the blend to register the voltage change has anyone successfully done this and willing to share some info and or files?

im close to having a working system but it seams like im missing something.

I'm about to undertake this but have you added the necessary field on Evoscan to see the ethanol content?

You verified that theres a voltage change on the pin wired to the ecu?
