Default Ethanol question. - 02-06-2019, 11:15 AM

So I can get 93 here in OKC, but only at a few places and it's way more expensive than 91. So, I generally mix E85 with 100% 91. I have a 12 gallon tank, so 2 gallons of E85 mixed with 10 gallons of 100% 91 nets me Roughly 93.3 octane and 14% ethanol.

Our E85 currently is testing about E70, though. So the same mix nets me 92.3 octane and 12% ethanol.

My question is, does the JB4 adjust for different octanes/ethanol content on its own, or is this something that will be added in the future with a new map?
