Default NA 97 IAT Sensor calibration

Hey,

When the car is cold (a few days cold) the CLT reading is the same as ambient and IAT is 8C lower...

The calibration values I used are the same for both:
bias resistor setting of 2490 ohms:

Temperature F / C Resistance In Ohms
-4 / -20 16150
104 / 40 1150
176 / 80 330

I lowered the IAT bias settings to 1800 and now the IAT is the same as CLT when cold.

Have I done good ?

Thanks !
