I pulled the data ... again I have 20 signals coming out of my ECU and I 
never checked the connection or anything ... but what I observed was a difficult 
measurement ... assuming everything was well connected and I was monitoring the 
correct pin.

28C = 0.891V
32.2C    = 0.897V
35.7C    = 0.906V
.......
63.7C    = 0.973V
72.8C    = 0.993V

Only 0.103 volts change for 50C change. It looks like a bit of a nightmare 
the higher the temps get ... but this is the highest I measured. Again I spent 
30 minutes on it and all 20 outputs are coming from inside the ECU and I always 
triple check the work first ... this was a quick feasibility test. It was one 
of those things I wanted to monitor. I did the coolant at the same time ... 
not a lot easier to deal with.
