Hey just got an xcal2 for Christmas. I followed directions and unhooked all fan fuses and fuel pump fuse before the tune. Plug it in and go to custom tunes (which are supposed to be for my 4.0 from Brenspeed) But it keeps telling me wrong vehicle. Any idea? Please help.

 

well the tuners "lock" to a certain vehicle. when one of the tunes is put on a vehicle it saves that vehicle's stock tune and you cannot use it on any other vehicle until the stock tune is put back. maybe they sent you one in use...[&:]lol. or it could just be the wrong tune/tuner (someone else's order). you really need to call them to set it straight.
