Stoich for 10% ethanol is 14.2, but if you haven't set your wideband up for that, it's ok. You will read 14.7 stoich even though it will actually be 14.2 if you are running 10% ethanol. Hard to explain. Im sure a tuner can come in here and explain better than i. By my gauge being set up for 14.2 stoich I am seeing exactly what I am getting with the fuel I'm running.

Me being at 11.2 at wot is like a 100% gas engine at 11.7. If your gauge was set up for 100% gas and you were seeing 11.2 you would be rich.
