Default Mines Tuned for Blended E85

No real noticeable difference. In fact good ole 91 produces better pops and crackles than when I blend it with E85. Does run smoother. Gas mileage meh 😑

If you are tuned on a blend of e85 and notice no difference then you need need tuner. The purpose of e85 is that it burns cooler and its a higher octane rating. So you can be more aggressive in the tune with timing etc.

Yes, VAP told me that even the summer blend 91 octane gas is probably not to par with 91. E85 is supposed to help boost it up to 93, which would no doubt make the engine run better in the case of pure gasoline. However, the question is whether E85+91=93 with a tune is viable, as opposed to straight 93.

Perhaps short term fuel trims were being maxed out?
do you have any pictures I could check out for Fitment if your Water - Methanol kit? I was thinking about getting a set of spacers for the runners made and fabricating a port injection to run this type of system. I have an Interchiller kit that I still have to figure out once I rebuild my block but this would be a great addition. Engine saw some very high IAT and decided to send two pistons home early. That coupled with over 29.7psi of boost probably scared them off 🤣 (maxed out my 3 Bar MAP sensors capabilities to read any further values of boost) but with that being said forged pistons to accompany a stage two Trans build and a bigger tune should really hit a little different. Did you have to tune for this even though it’s auxiliary and doesn’t run full time? How do your fuel trims look when this is activated? Have you ever had any Fuel Trim Codes when it hits?

What mpg are you getting? I mean its a decent difference in costs to refill it, right? U save a decent amount more I would imagine. Is the difference in pops and crackles large?
