This was before I fueled with E-85 and with FlexTek in the "gasoline" setting. In hindsight, the subsequent and occasional illumination of the check engine light was probably due to the weak/failing fuel pump. Surprisingly, there was no check engine light after my first E-85 fillup when I switched FlexTek to the "ethanol" setting and gasoline was likely still in much of the fuel lines. One other item of note is that the average fuel economy reading from the trip computer was no longer realistic. Normal readings around 25 to 30 mpg shot up to around 45 to 60 mpg after FlexTek was installed. I was expecting somewhat reduced fuel economy and was a bit shocked until I realized that the fuel flow is not determined by a dedicated sensor, but is gleaned from the fuel injection system. Actual fuel economy calculations indicated a 5% reduction in fuel economy with E-85. Walt 1991 9000T
