Paul, just a note of caution, if you are tempted to use the small Mazda coolant sensor location on the rear housing near the oil pressure sensor, be aware it is very none linear (perhaps the Mazda coolant gauge is as well {:>)) - if you are using another sensor then disregard. I thought I was getting temps of over 250F by monitoring the Mazda Sensor in that location - until I calibrated it in a pot of water and found out the temps were closer to 210F.

The engine has a stock water temp sender next to the oil pressure switch. I will try using that to send temp information to my engine monitor. If that does not work, I will install another temp sending unit like the one that came stock in the water pump housing.

Glad to hear you're getting real numbers now, give or take that silly metric system :-) I'm not sure what the specs are on the stock sensor, but you can get aftermarket sensors that fit the rear housing hole. The thread is M10 x 1.0, and egauges.com has them in at least the VDO range of resistance.
