I was planning on using 5 gallons of the E85 with 10 gallons of E10, which is about 30%. I have a ethanol tester on the way so I will know how much to use to get that ratio. I am going to make a maf adjustment because my fuel trims were lean, but other than that I don't think I will change anything.

we drove to that town because my wife had a job interview, and if she gets the job she will be driving there everyday, with the potential for a move. it's only a part time job so like 6 hours a day at 15/hr, but there is good potential for advancement. I'm hoping she get's it, so I can just run straight E85 when/if we move.
