SCT X4 Flash Tuner

The SCT X4 flash tuner offers powerful custom tuning of your vehicle's computer and HUGE Backlit display, the SCT X4 Power Flash makes it EASY to read the Built-In Data Logging or Real Time Monitored Vehicle Data. Each X4 can hold up to 10 custom tunes, plus it holds your vehicles factory stock tune so you can return the vehicle to stock at any time. In addition to the literally thousands of parameters we can custom tune for you, User-Adjustable parameters let YOU modify up to 14 settings (number varies per application) such as shift firmness, rev limiters, WOT spark advance, speedometer calibration for gears, etc.

The X4 has Built-in Wifi allows you to easily attach to your local area wireless network to download device updates. You can also Read, Clear & Diagnose Trouble Codes without the expensive diagnostic fees charged by dealerships or your local garage.

The X4 backs up your factory PCM program during installation should you ever need to return your vehicle to the stock program. Restoring your vehicle to the stock PCM program is as easy as selecting "Return to Stock" from the device menu. With all SCT devices, once returned to stock, there is no footprint or trace of the tune in the vehicle's PCM.

WE BUILD CUSTOM TUNES FOR EACH VEHICLE.
