Calibrating the Oil Temp Sensor

I was hoping beyond hope that the Dynon oil temp sensor might be reading incorrectly. I was hoping that I might have a bad connection which might cause it to read high.

No such luck.

With the assistance of Prof. Charley Rodriguez I ran the engine and got it up to almost 220F. We took several comparative readings in the oil sump and found that the Dynon sensor and the lab quality thermometer agreed within a degree or two.

Today I will work on stabilizing the EFI sensor mount to eliminate the miss, then will figure how to cool the oil. I have a couple of ideas there and do have an oil cooler waiting in the wings if I decide I will go that route.
