The X4 SCT Flash tuner is the latest in a line of flash tuners that were introduced in 2005. The introduction of the SCT Flash tuner was a huge leap forward in the tuning industry.
Until its introduction we were not able to access the Ford Falcon ECU. Tune shops were only able to use piggy back computers. The current X4 flash tuner is an excellent product.
Once you purchase a X4 flash tuner it is capable of storing up to 10 tune files as well as your original std tune file that you can reload and retune the car back to stock at any time.
You can use the SCT Flash tuner to read trouble codes, you can data log your engines parameters. You can also play them back on you PC. Another cool thing is you can use the flash tuner as a display to show engine function and gauges.
