So years ago, I ran my Silverado SS on E85 with basically nothing more than telling a lie to the computer... I told the computer that the injectors were 35% smaller than they actually were (42# injectors installed, I told the ECU they were 27.3#). Aside from that, I did add spark and some minor fuel trim adjustments, but no stoich or command fuel changes, and nothing else was "needed" to run E85. Is there an injector constant on the Ford tunes to do something similar with my new 2014 Track Pack 5.0, or would there be a different E85 tuning strategy all together on this platform? Just wondering what some of you have done before I click "buy" for my third in my lifetime HPTuner setup.
