If you have previously purchased one of our ECU Tunes, use this page to update to the latest version. This only applies to updates for the same car and modifications as the original tune you purchased. If you want to change fuel type or stage of tune, you will have to purchase a new Staged Tune. If you want to change selected options for a previously purchased tune (launch control, traction control, burbles, etc), please use this link: Staged Tune Options Change
