has anyone tuned for E85 fuel? I currently run Sunoco 260 GT 100 octane in both my commando and Dominator with great results. I have a GT350R mustang which from the factory is not E85 capable, but by tuning and allowing the ECU to read from the oxygen sensors it adjust the fuel needs to allow the use of E85. The beauty is, it can run straight E85 or any mixture of it and self adjust without any driver input. I can run straight E85, a mixture of both 93 and E85 or E85 and 100 octane. It doesn’t matter, the ecu adjust for it. The benefits of e85 over fossil fuel is.. Higher octane (116 octane rating for E85) Cooler And cheaper. Dyno testing my mustang on 93 octane in 100% stock form I pulled 484 rear wheel hp. AddIng only a tune and same tank of 93 octane I pulled 496 rear wheel hp. Draining the tank and tuning for 100 octane Sunoco 260 GT race gas I pulled 511 rear wheel hp. Draining the tank and tuning for E85 fuel I pulled 537 rear wheel hp This is all on the same dyno. Same day testing. I would love to try e85 in my bike if the tune capability is available.
