I let my gauage sit in the car, next to the other guages
Sits between thr 8 and 0 of 180. Not sure how "sensitive" the guage is meaning, it could be that unless the car hits 220 degrees the guage might not move from this "180" position. Manufacturers do this so people don't complain everytime they see the guage moving up and down, which is more realistic given the demands one puts on the car may change during their drive.
