SCT Tuner has merged with Bullydog Tuners and Derive Systems, and has changed most of their websites and support pages. I’ve updated the links below (as of 7/20/2021) so they go to the new support pages, but the X3 Tuner is no longer supported so there is no way to get updates for it.
But if you already have the software, this guide might help.
If you’ve never done this before, it’s very frustrating to get started with all the right software.
I will add pics soon, but here are the basics.
How to use the SCT SF3/X3 tuner with your computer:
(written for LiveLink v.6.1)
What to do next? While on SCT’s website, download the manuals for the SCT SF3 Ford, the DashScan, and more by going to: https://derivesystems.helpjuice.com/49353-sct and searching for “Product Manual”
Also at that link there are videos on “Updating your X3 or Livewire flash device” and “Formatting your X3 or Livewire flash device”.
You should be all set to use your SCT tuner with your computer. Now you just have to use it on your car!
