I'm going to add food for thought, I was at the dealership the other day, over heard the decussation with a guy who was asking about using "The Pedal Commander" on his Rebel, the truck is till under factory warranty, there advice to this person was to not install it, doing so he ran the risk of warranty being denied, when he ask why he was told they are being asked by FCA if The Pedal Commander is installed after certain warranty claim have been filed.. From what I have read it should not cause problems with the ECU, I'm just passing on what I over heard not only service writers but also service manager agreeing with SW telling one of their customers who bought the truck from them to not to install it....
