SCT X4

The SCT X4 handheld programmer is one of the most popular tuning devices in the EFI tuning industry.  Simple to use and loaded with tons of other features it definitely makes the SCT X4 stand out amongst it's competitors. The X4 comes pre-loaded with several different calibrations for your vehicle which are proven to increase horsepower, torque as well as improve drivability and fuel economy. In addition to the pre-loaded SCT tunes the X4 is capable of storing up to ten custom tune files. So if you're looking for something more than one of the pre-loaded tunes any SCT tuner can provide you a tune for this device. 

The device also allow for you to make user end changes to things such as spark, fuel, rev limiter, tire size, gear ratio as well as many other options giving you more control of your vehicle. 

The X4 also has datalogging capability. What this means is that it will not only display in real time but also log and save information about the car while it's running to be reviewed at a later date by you or your tuner. Anything that's monitored by the PCM can be logged by the SCT device. Things such as air fuel, battery voltage, fuel pressure, fuel trims and MAF counts are all things that can be logged. Additional sensors can also be used to monitor other things that the PCM doesn't normally read on some vehicles (EGT's).

The SCT X4 can be easily updated through WIFI or by being plugged into your computers USB port with the USB cable provided with the device.
