You would get nothing out of E85 without a sensor & tune or piggyback controller with a virtual sensor -- you may even risk harm without some tuning assistance.
Even the piggybacks with virtual sensors are not what I would consider the safest. You get x gallons of E85, then fill the rest of your tank with the highest octane E10 you can get. After that you have to drive your car side to side to ensure good fuel mix and make 3 WOT passes for the piggyback to use the knock sensor to determine your mixture and octane rating before it will properly remap your AFR. You have to do this every time you fill up.
Only safe routes are to blind tune at E60 equivalent (not preferred) or get a flex fuel sensor and proper tune that will adjust whether you run full E10 or full E85 (and any blend ratio of the two).
