The JB4 doesn't have the ability to advance timing, and Cobb isn't able to get close to the horsepower numbers on E85 (even with a whole list of supporting mods). Most importantly, as I mentioned in my first post, the PROcede is the only tune that incorporates a flex fuel sensor, so your car is running optimally for whatever fuel blend is running through the system. It's been proven that its impossible to predict the exact ethanol concentration reaching your engine at any given moment, so manually adjusting your tune is borderline dangerous.

Right now, Vishnu offers the only complete solution to running E85 in your car. OP asked a question and these are the facts.
