Stock location of the ECM temp sensor in Inake...
... that is where I am running mine now. I heard people talk about how the dash temp gauge is typically off because of age related things but I used a fluke infrared temp sensor to check the intake sensor and the gauge sensor in the head and they both were reading correctly, but the intake one was almost 20 degrees less. Since this is being used for fueling and fan operation, should I move the ECM sensor to the head?
I also got a new reverse poppet 190 thermostat installed. It is for a Hummer cause it was one of very few that I could get in that temp. It took a little grinding of the perimeter and I ended up using a summit o-ring style housing cause the stock one didn't fit. ANYWAY, the bird is running much healthier now that the 180 is out.

How do you explain the temp difference?
My logs show the CTS temp within 5 degrees of what is showing on the temp gauge

Either that or the heat from the headers is heat soaking the gauge sensor. I'll play around with it more today and get a chart for comparison.
