    Reading Fuel Composition

    2005 GTO, E40, Flex sensor
    My alcohol percentage used to work in my Channels. Now I cannot get it to read on either of the Alcohol selections. The Sensor that reads in Frequency works but I don't know what 118hz is equal to in percent. Is there some way to change frequency to percent? I have Alcohol percent shown in charts also and no numbers there.

    I found a chart that lists hz as a percent of alcohol, so I guess I will use that.

    Did you try repolling for supported parameters and going back in to see if you could add the channels after that?

    Thanks! That did it. I don't know why sometime things change in the scanner. I made two drag runs last night and my tps read 37% when it was 100 and trans temp read 32 degrees.

    I lose channels all the time for some reason. And it really sucks if you go out and waste a bunch of time and gas logging and then don't have the chanels you needed working when you go to look at the data. I've made it a point to verify I'm logging everything I need every time I hook up
