Yes, the ECA-2 has a 5 volt output that can be used as an input (Ethanol % = 20 * Voltage)

Also, I could get the ethanol content and fuel temp from a typical GM flex-fuel sensor. They have an output of 50 Hz (0% ethanol) to 150Hz, 100% ethanol.
That is easy for a microcontroller to measure and calculate.

With that said, I haven't done this, so I would need to do some testing.
