I have never used one, but here's what I think I know about it:
Your pedal does not have a cable. It's an electronic rheostat that's wired through the ECU, and then to the an electric motor on the throttle body. It sound hokey, but most cars and trucks are built this way now. Even Harley does it, and you know how far behind the technology curve they are.
With this set up, your foot does not control the throttle, the ECU does. The manufacturer programs the throttle response according to their needs. Torque management to soften launches and save the drive line, slower throttle response for better city mileage, etc.
The Pedal Commander plugs into the top of your pedal, and then the factory plug goes in to the PC. It modifies the signal that gets sent to the ECU. It doesn't modify the ECU or any programming. It's not a "Tune" in the traditional sense. So, in theory, it won't void the factory warranty - but it might, so be careful.
Companies that actually provide a tune to modify the ECU, will usually make changes to the throttle maps. If you plan on adding a real tune at some point, the Pedal Commander will become obsolete, and you'll probably have to remove it.
