    My IAT sensor is reading anywhere between 45-55* when ambient temp
    is 95*+.
    According to the power tuner.
    Is this a sign of a bad IAT sensor.
    Can this be affecting my tune in anyway?
    Pulling or adding timing?

    Sounds like the sensor is indeed misreading.

    Would this cause my tune to be off?
    How bad would it affect it?
    Where can i get one?
    Sorry, too many questions.

    A local member sent me this message:

    IAT values will be displayed in celsius.

    95 fahrenheit is 35 celsius, so your IAT sensor is reading correctly, just in different units.


    Is this right??

    45-55C is 113-131F.

    What type of intake system do you have?

    I have never heard of an iat that went bad that read that.
    Again I think you have the unit of measure changed to * celicius

    If you have that intake, the IAT might be right. It's just showing Celsius for some reason. That intake sucks in a lot of hot air and I wouldn't doubt the intake air is that temp.
