This pretty much says it all. We have been testing all kinds of mixes, and ethanol on the OTS E30 tune. So far things seem pretty happy between E30 and E60. This should hopefully eliminate the need to be super exact, but testing should always be recommended. So far from what we have been doing is 3-4 gal of E85, and the rest pump gas (assuming you are just under a 1/4 tank).

From earlier conversations the tunes are supposed to be FTCL. So there shouldn't be much concern unless the mix is too low and induces knock. Aim high is my only recommendation.



Fueling will be adjusted to the target. Won't be an issue unless the target is too lean for the mix. However timing will not. So the only inherent risk is if the mixture is indeed too low.

Bottom line.... If you don't have flex you need to be testing yourself.
