electronic accelerator pedal sensor?

I am trying to increase the idle rpm on my car, and wonder if I install small set screw so I can fine tune the return position of the pedall.  Mechanically this will work,  but I am not sure will ECM or PCM will re learn the new return position of the pedal after some driving and reset it again to "0%"  ?

Sounds like a transducer........

Fix the real problem causing low idle.
