It doesnt effect fuel trims much if I have closer to E85. Although if I'm running closer to E10 it throws the fuel trim off momentarily. Not a huge deal but it would be nice if I can avoid that altogether with a stable signal.

Yrs a lot of flex fuel kits do this as battery volts drops during cranking so does the ethanol signal volts, oft kits seem to be particulary bad but most do it to some degree. it can cuase issues in cold starts as ethanol content drops so does cranking fueling. Ecutek has an ethanol hold feature in coding to sort this but not in openource
