Sounds like you were not running VMSpc. I have mine set up with audio alarms for low oil pressure and high coolant temperatures. I run my coach on the VMSpc rather than the dash gauge and don't run mine as hot as you do. I start taking alternative measures as 205-207 degrees. My dash temperature gauge has gone stupid on me so I need to replace it. It use to run fairly close to the VMSpc until about 200 then climb faster than the VMSpc. Now it is just unreliable. Sometimes it tracks VMSpc and sometimes it reads 10-30 degrees higher than the VMSpc. The dash gauge and the DDEC readings use different sensors in different locations but my infrared temperature gun shows VERY close readings at the two locations.
