Anyone know what would cause an e85 analyzer to stay at e17. It was working fine when it was installed. When I got my car back from being turned it just reads e17 now. Never changes. It is on a daul map. Maybe some 93 still in it. Haven't put any more fuel in it yet since getting it back

 

So do you know what is in your tank? Straight 93oct, a blend( 20% ethanol or greater) or supposedly straight E-85. What did you get tuned on?
