changing temp and coolant readings to fahrenheit

[motionper]

are there known sensors i can use or a changeover i can enter so my sensors read Fahrenheit i tried your chart and it's way off when i try a custom calibration is there another way??

On the G4 there is no way to have the readings in Fahrenheit. This is a function that has been added to the G4+ range

Any of the sensors listed in the drop down are pre calibrated.

If doing a custom cal the figures will have to be adjusted to match the sensor.
