    VTECH Logger reading constant 14.9AFR

    across the board. Plugged in a brand new WB free air, same thing. Detached the logger for 5 minutes, same thing. Detached the logger again and this time it read normal. Anyone got any clue?

    Maybe the logger isn't heating the O2 or reading it properly?

    When Logger looses contact with the 02 Sensor for one or other reason it reads 14.8 as default.
    I would check so 02 connector is connected as it should.

    If it is connected good then it sounds like a bad 02 Sensor.
    Test with another Sensor.

    I have. I've used 3 different sensors. It's Random. I've also checked the DL wires and they're fine

    Are you using an iphone to monitor afr's? I am having the hardest time trying to get the BRPDIAG app on my iphone5. The instructions are very confusing.

    It's random. It's weird as all hell. At least I know not to lose my mind when I see the 14.8 @ WOT now. I've only been out twice since this and now I'm down again for this charger install and some cleanup/water hose changes

    it can be your sensor starting to fail.
