GM ethanol content sensor
need an analyzer, harness, and sensor thats it. they are nice to have to see the changes in the E85 based on the season, and also to make sure the map you have is correct for the type of of fuel that is flowing in your lines. I got one when I did the switch to ethanol.
Free bump to the OP, good price and a nice addition.
