air sensor values C6

I was wondering if anyone knew where the "air intake" sensor get's it's value from, is it located with the MAF? The temp that is displayed in the car has it's temperature sensor located just inside the grill. Now when I log data from the predator and choose "ambient air" and "intake air" i am curious to where those sensors are located, because the ambient air doesn't match the outside temp, I am guessing that ambient air sensor is located in the engine bay somewhere. That said, where is the intake temp sensor? I am just curious because the intake temp sometimes goes higher, never see it lower than the ambient air. I have a Callaway Honker installed. Anybody know where these sensors are that are logged by the predator?

It is 1 sensor.
Ambient is the reading taken at start up, and IAT is the live value from the sensor.
If the car is heat-soaked on startup, it will display a higher ambient reading, if cool, it will be close to outside temp.

Thanks

Well, when I log the values though, the ambient temperature slowly drops down, which makes sense as i start driving. So it doesn't seem to be just from startup.
