I undertand the flexibility of our wonderful ECU.
My point was that I am *sure* that I am not running full E85. I had some gas in my tank. My car starts just fine in 9 degree F weather. My fuel trims are minimally adjusted. My IAM is fine. Just seems to me that if I were running something like 60% ethanol on a tune that's ideal for 85% ethanol, I'd see bigger timing corrections and bigger fuel trims in my logs....
