Hey all - very recently switched over to my FF tune as I’m trying to run the remaining 93 (had like 4miles to E) out of the system and put in a tank of e85 (e82-e83) how long should I wait to swap over to the e85r tune? Run out this tank then switch with a new one? Run out half ? Etc… obviously we all know FF tunes aren’t exactly the greatest to use just to transition. Any knowledge would be helpful - 🙏

It’s perfectly fine to switch over to the E85R tune now. I’ve done it many times in the more than 4 years that I’ve been tuned and never had a single issue doing so.

Okay cool - first time doing so just wanted to be safe. Drove about 20-30 miles since switching to FF tune so I’d assume all 93 should be out of the lines
