AIR TEMPERATURE (range of 0 to 200 degrees)

This is the temperature of the air at the MAS. It's great for seeing if your cold air intake or heat shield is working. On a 45 degree day I had temps of 120 degrees at the filter with just a K&N and cut air can. After making a cold air setup and a heat shield I now see 75 to 85 degree temps. This also has an affect on timing.

On VPC cars, the VPC will tell the ECU that you have a constant temp of 67 degrees at the sensor. This is not adjustable on the VPC.
