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.

One last question, when are you going to have this available so I can get rid of all my other gauges and the big wad of wiring buried behind my cubby panel?
