I didn't look to carefully, part of it could be that the values are changing because I had the the engine running and I was trying to keep up with my old rotary switch type decade box.
Pretty sure though the guage will not go to the end of the red until temp is a lot higher 140-150 C. Again, I didn't even double check the numbers I have coded so might be just me. Light does come on over 125 C regardless of the guage though, which is good!
