I've made some linear CALC PID's for the analog inputs that work great for other sensors, but can the "6th order" equation be used that Aeroforce provides for this sensor?
Equation is y=(-1.0922*x to 6th power) + (16.409* to 5th power) - (95.492*x to 4th power) + (273.85*x to 3rd power) - (405.02*x to 2nd power) + (332.73*x) - 43.188
If the linear can be used, I'm not sure how to enter the power vs the full equation
Its for a supercharger coolant inlet temp and the temps calculate TOO COOL in the lower range of my temps with their linear equation of y=55.51x-0.2051
They provide a "low temp equation for 15-75 deg F" y=78.298x-12.411 , but then the higher end of my temp range gets way to high.
My operating range is more like 50-120 F and either linear equation has large errors compared to the 6th order conversion.
