GM has transitioned to an idiot light gauge for several years now in various models. Most cadis have had these gauges for at the last 10 years. It goes to a set temperature and sits there unless there is an over heating issue when it will climb and a DIC message will come on,

pretty stupid but who knows why they chose this????

Considering the dash display matches the OBD reader (black and white dot matrix box in the picture) I would assume it is correct.

I would be OK with this approach EXCEPT the idiot step gage is all we have in sport and track mode. There is no digital water temperature display available in sport or track mode, only in the Touring Mode summary display shown in the picture on a prior post. All I can hope for is that the gage again becomes accurate if the true water temp is above 220 degrees. I will compare it to my OBD data logger the next time I go to the track. As I said before, the track seems to be the only place you can get a C7 above 220 degrees water temp.

Thanks,
