SCT Performance has been on a hot streak the last few years by debuting new tuners for a variety of budgets. One tuner that’s gone overlooked just happens to be their best seller – the SF3 pre-loaded tuner and the X3 that’s designed to be used with custom tunes. The Livewire received a facelift two years ago with an all-new touch screen color display and it only made sense to make similar updates to the SF3/X3 programmer.

The X4 will only slightly increase in cost over the current SF3s – Tim Roi

“The X4 will only slightly increase in cost over the current SF3s,” says Tim Roi of SCT. “Look for them to hit the shelves early 2014.” As you can see in the above photo, the new X4 is dimensionally smaller than the SF3 and boasts a full color screen that is much easier to navigate. The OBD-II port remains wired and uses a smaller, Livewire TS-style, plug that connects to the top of the device. Also the X4 will come with a window suction mount and is slotted on the back to lock in place, again, much like the Livewire TS.

One of the most exciting changes is the ease to update the device. Instead of having to connect to a Windows-based computer for updates, the X4 will have integrated WiFi that will allow update through a standard wireless connection. Rounding out the features are 2 analog inputs, ability to hold 10 custom tunes, multiple datalogging screens, and better navigation with its updated scrolling buttons.

We assure you that we will review the new X4 in its entirety in the coming months, so stay tuned!
