thanks!

I just replaced my OEM thermostat with a low temp thermostat.
I then took the car on a 297 mile run with my scanner plugged into the OBDII port.
This allowed me monitor the temps that the ECU was seeing and compare readings to the dash display.
Ambient temps were from 61 degrees in the morning to 93 degrees in the afternoon.
Coolant temps ran from 183 -205 degrees depending on engine load, ambient temp, road speed, and RPM.
Coolant temps reported by the scanner corelated very closely to the dash gauge.
I have done this same test with the OEM thermostat. on the same 297 mile run.
Coolant temps in that test ran 5 degrees higher through the range.
Also I don't think the fans kick on until around 196-200 degrees. At least mine don't. Mine is a 2000S
Just as an edit to this: I looked up the trigger temps for the fans.
Low speed kicks on at 206.2F high speed kicks on at 215.6F
