The scangauge is not reading outside air temp. It is showing you the intake air temp. The sensor is in the intake path up by the throttle body. It is only accurate while you are moving. Otherwise heat of the engine starts getting sucked into the intake. But as long as you are moving so there is ram air coming into the grill, it is a very accurate temperate sensor. I use it in the winter for the very reason you want it.


EDIT... Wait, is there an XGAUGE I don't know about for OAT?
