Instructions for Downloading a Tune to Your Mustang's SCT Device

NOTE: If you purchased an SCT X3 Power Flash Tuner before July 25, 2008, you will now consider your tuner to be an SF3. The X3 is now a blank, custom, tune-only device. If you have pre-programmed tunes, your device is considered an SF3, regardless of what the device actually says on it. Any updates for your X3 (if it has pre-programmed tunes) will be downloaded for the SF3 P/N: 3015

1. Log on to your internet, and go to www.sctflash.com.

2. Once you have arrived at their website, look at the top of the screen. There is a bar across the top with some buttons. You need to click on “Tech Support”.
