This product requires the customer to ship their ECU to Geiser Performance along with a printed copy of your order. If you want the ability to flash your own ECU, change tunes, return to stock, datalog, etc, please see Maptuner X.

PLEASE INCLUDE YOUR VIN NUMBER IN THE COMMENTS SECTION AT CHECKOUT. WE CAN'T TUNE YOUR ECU WITHOUT THIS.
