    Negative Intake Valve Temperatures WOT?

    Guys, just happened to see in one of my logs at WOT the intake valve temp was in the 250C range and then went to negative 250C (ish).

    This seems odd, curious if other see this or have an explanation why it is switching. I am curious if there is a bug in the scanner or if this is a vehicle thing.

    Check out the attached log at 5 minutes.

    This is a bug in scanner software? Engine control functions normally?
