I am trying to setup a RIFE IAT sensor in M1 Tune but the data for sensor configuration RIFE provides is in Ohm vs temp rather than the Voltage vs temp that the M1 Tune translation needs. How do I make this conversion?
You use ohm's law and the voltage divider equations to convert the resistance of your sensor and the power supply (5V) and pullup resistor (1k ohms on M1 Temperature Inputs for internal, whatever you used if external) into voltage.
Here is an example calculator to help you with that math:
