I would need the following information:
Vin#: ( Please check multiple times for accuracy)
Federal or Cali Emissions:
ECM Calibration: To get this number, plug the smarty into your truck holding the 5 key ( Down arrow if your using the Jr) until the smarty lights up. Then, go through the menus as if you are trying to program the truck. At a certain point, Smarty will display the ECM calibration for you. Smarty Touch shows information on the information screen.
Hope this helps!
