That cannot be done from a simple download, the vehicle should be taken to a shop where they can program the ecu for you. most late model cars don't have removable chips in the ecu anymore. a good aftermarket/custom shop should be able to either program the ecu you already have or install a piggyback system that will work with your new exhaust.
