Thinking that if the Banks unit fails it will only affect the throttle is a pretty big assumption on your part. A Banks unit connected to the ODBII port is also connected to the high speed CAN bus - which could affect almost EVERYTHING in the truck. The Banks unit controls the throttle position via the CAN bus and the PCM - if it were to go "haywire" there are many things on that CAN bus that would be affected.
The Pedal Commander is connected between the pedal position module and the PCM - it does not connect to the CAN bus. If it were to fail it might make the pedal inoperative - but that is where it would stop. The Pedal Commander is powered via the voltage supplied by the PCM and the outputs on the PCM are current limited. Even if it failed as a "short" (highly unlikely) it would not damage anything.
All things equal, would I worry about either unit failing ? Not any more than any other solid state device in the truck - which there are hundreds.

I'm looking to confirm something. For those who have actually experienced a real world Pedal Commander failure, how did the fault manifest itself (DTC codes, driving behavior, etc) for you? Failure seems to be rare, and that's a good thing, but I need some data to check something. Thanks
