Water coolant temperature gauge too low

Hi everyone.
Can the Water coolant gauge be recalibrated? maybe using Xentry software?
Because a little annoying the gauge show 10 degree too low, compared with real temperature. (Yellow text)

I am unaware if you can calibrate it or not but some coolant gauges are doctored.

CONCERNING TEMP CONTROL

this is just the tip of the proverbial iceberg.

Have you noticed if your engine fan being ON in winter ??

The whole engine temp control is poor not just the liar-gauge.

Does your engine accumulates extreme heat ?

Have you noticed the temp display deeping low on the freeway?? that's a learned reaction to extreme heat.
