In the off position, the real IAT input would go to the ECU/PCM. In the other R positions, you could have a breadboard with different (and changeable!!!) resistors of your choice. That way, there would be no "jumpiness", but you would still have control over the range of IAT temperatures.

Hrmmmm, sounds like a kid's electronic project to me. Where's my crystal radio kit!?!?!?!?!?!?
