I got a ticket on my way to the only Thorntonís station in my area. I was trying to get ethanol with the best reputation of stations in my area. Didnít even get a tune on it yet. Ugh

Same issue. Noticed it last fall and thought they lowered the ethanol for winter which is when I was going to swap to the 93 tune anyways. Well it started up this year too. Seems that I can make it a few weeks with no issue and then it spontaneously starts up. Reflash the tune with the same fuel and zero issue for several more weeks. Never went lower then 0.750 except for today it dropped to 0.675 or whatever the next down is. It's especially strange because I just flashed this time again yesterday so it might actually be bad fuel this time. I've never had an issue adding extra e85 since it's a pain to calculate properly. I usually do 6 to 7 gallons of e85 when my gas light comes on. Tried adding more before when the DAM would drop and it didn't fix anything.

Mine seems to be doing okay at ~40% ethanol lately. DAM dipped to 0.875 and came back up on its own fairly quickly.
