They send signals to the pcm / ecm, and based on a bunch of other info,pcm / ecm DECIDES whether or not, and how quickly, to eventually do with the throttle what you did with your foot.Luckily in the vast majority of situations this can be tuned to behave extremely similarly to a physical cable throttle in nearly all situations.PPVs & SSVs turn up the idle a bit to keep all the extra electronics happy.Idling @ up to 625RpM in gear & 725RpM in Park / Neutral is noticeable, but only for those paying attention.Before the pair of '05 electrical fans / back when I was stuck with the '02 mech propeller,turned the idle all the way up to 750RpM in gear to keep AC nipply-cold in June/July/August. I actually remember this feature in my - formerly my - 2012 Yukon XL saving my @$$ during a very curvy downhill, brake pads were low,powertrain braking helped me slow down.Don't know if this is completely tune-out-able, but if it can't, bet it can be turned down from a scream to a whisper.</blockquote>
