E85. I installed the injectors myself the weekend before the tune and they were brand new ID2000's in the plastic. The car was started 3 times total until Greg, Seb, and I found the faulty injector issue due to rough idle and missing cylinder. The car was on pump gas and hooked up to a haltech with an ethonal content gauge with a flex fuel sensor which read 0 as the ethonal content. The injector ohm'd same as the rest and was even swapped to another cylinder for further verification. I believe it was just a bad injector from ID. Brett worked with Greg and took care of us so we could still tune. These other E85 worries came about when talking with injector dynamics about the problem.
