I’m thinking about engine monitors and what parameters I need to watch.  I’m wondering about the value of cylinder head temperatures in a water-cooled engine.  For an air-cooled engine, CHT is valuable as a measure of engine overheat.  For the water-cooled rotary, the coolant temp supplies that info.  So, what is the additional benefit of monitoring CHTs (in addition to coolant temp).

What am I missing?
