When you fill back up with 93/91 (and that's mostly what you have in the tank), load the 93 tuneThat’s not my question. It’s how to switch when e85 is not available (not many stations around me have e85 and 93 needs to blended from 100). So if I fill up on a road trip and I’m down to 1/4 tank, it’s essentially e30. Then after another refill, it’s back to 91, how to switch between them.
Since this is my daily, I’m thinking this isn’t for me. Maybe the Ford procal if/when it comes out for 91+ (since I’m already blending/running 93).
When you fill back up with e85 (and you only have a couple gallons of 93 or whatever) load the e85 tune
I mean if you really want you can run the car for a couple minutes to clear the lines out before changing but it's pretty simple
