Forgot about this thread. Not much to update. I have an e85 tune that works well enough for me maybe a little more constructive than I could get away with. I've made no physical changes to the car to run the e85, including an all stock fuel system. I have been using bitedit to make my tuning adjustments. I'll be switching back to e85 soon for this year with some minor changes to my car, I anticipate no problems.
