Re: MTX-D EThanol Sensor reading high!

Hi Hondata,

I use a the GM ethanol sensor because I’m running E85 which 50-85% ethanol here in MN. I use the table under the Flex Fuel tap on the s300 v3 to add more fuel as ethanol content goes up.

I recently installed v 2.7.7 software and updated the firmware.

I see in the release notes and on this thread that the ethanol content was reading too high in the previous versions.

My question is…. Was the ethanol content correct in previous versions (pre v2.7.7) for the GM sensor? If not how much was it off? Thanks
