Flex fuel setup

[LSX427]

Hi David
I bought a new sensor and find out that my sensor was bad.
But this new sensor still has a higher reading of around 6%.
And then I measure the sensor output frequency it was pretty close to actual ethanol content.
Compare the Fuel Composition number and frequency number is where that 6% come from.

Thank you for all the help, David!

by 6% u mean 91% content,if so -its pretty normal to have pump e85 having content of 90-93% from the pump station

No. I'm measuring pure ethanol(99.7% on label), the sensor gives 105% reading.
