    E67 flex fuel sensor activation

    I just installed a flex fuel sensor.
    Pink wire to 12v ignition
    Black to ground
    White to pin 5 of J1 (blue) ECM plug.

    I get remote tunes as I am a long way from tuning on my own.My tuner is unavailable. I am not getting a reading from my sensor when I datalog. I am very confident I wired the pin properly. If anyone has a moment can they look at my tune to make sure everything is correct for it to work?

    Enabling the sensor would be an obvious place to start...

    fuel-->open/closed loop, Flex fuel sensor "enable", sensor type "sensor"
    Post a log and tune if you want help

    Thank you.^^
    I saw that in the tune and just didn't have the confidence to change it without a knowledgeable 2nd opinion. I was told the new tune was flex fuel ready.
