So yesterday i filled up with my usual E60 ratio and was confused as my ethanol reader leveled at E46 where im always low 50s-57 on that ratio so today with about .65 of my tank full threw in 3.8 gallons of e85 to try to get it back to e60. It's leveled out at e50 now which makes absolutely no sense.
So my questions are:
Could this be an Ecu issue? Just a reader issue? or bad e85?
Also just want to make sure that my EcuTek tune is compensating for the fuel ratio despite what the reader is telling me.
