if you're setting your stoich to 10.0 or 9.75, or 9.88, you're an idiot. "well they told me this was the stoich of e85" no, not even close. "i tested it with a test and it said 85%" again. no.

here is a question lesson for you. run your car empty on fuel. fill it up. log the fuel trims. do some simple math and see what number you come up with. if you're maf i anywhere close to where it is supposed to be. you will see something fun happen. take your stoich commanded afr and divide by the percentage of the fuel trims. what commanded afr do you come up with after this?
hmmmmm?

hate to say it to ya bud, there is a hidden fail in this. over a certain amount of time there will be a film build up that can not be removing by simple solvents. for some stupid reason gasoline takes it off with ease. more or less the by products that are left in the tank and get picked up by the ethanol. so every 6 months or so, run a two tanks of gasoline through the system to clear this mess out.

hahaha you just made my point. I dont know anything about tuning so for me to switch to 93 is a 5-600 ordeal. whereas for you it would be no big deal due to your expertise in tuning. That is almost the price of hp tuners... It would almost make sense for me to buy it and learn a bit about tuning so i can do this and possibly switch it for long trips.
