As have I, but $20 for a bluetooth OBDII and hybrid assistant get it done with minimal effort.

Issue I have is that they are NTC sensors, so as temperature increases, resistance decreases. If they were PTC, just add a resistor in series, but being NTC, the only way to do it is to put a resistor in parallel, which completely jacks up the resistance/temperature curve.

Hybrid assistant is a no-brainer. Let the car manage it up to 100F. Once it hit's 100F, full blast cooling.
