It is not an Ecm it is a programmer. Turn the truck off and plug the tuner into the OBD port under the dash on the drivers side. Plug it in and follow the instructions on the tuner. It will go thru a series of screens and it should give you the option of returning to stock. Select this and follow all instructions.
