PRICE REDUCED FOR LABOR DAY SALE! So, where's the "plus" in Flashcal+? The combination of Flashcal+'s wireless dongle and app is every bit as powerful as the existing "F5" series Flashcal, but enhanced with the smooth interface of your smartphone's touchscreen, freedom from running cables with a Bluetooth connection, and excellent on-the-fly controls and monitoring. This means Flashcal+ ("Flashcal Plus") for Gladiator JT 3.6L is WIRELESS! Superchips is proud to announce that our newest generation of electronic calibrator is a powerful combination of smartphone app and Bluetooth dongle to tap into a vehicle's OBD-II. Flashcal+ isn't another device to make a quick change and toss back on the shelf. Our engineers have provided the exceptionally fast Quick Options Superchips devices are known for and acts as a live interface to your Jeep's electronics for constant access to control and view data. Flashcal+ for Gladiator also contains a huge amount of control on the vehicle's subsystems through its body control module (BCM) to enable existing circuits and add or delete features like a backup camera or blind spot detection. It can also disable functions such as your electronic steering pump to convert to hydraulic or the electric lockers to convert to aftermarket manual units when building a trail-ready rig. There are also numerous options for changing your vehicle's lighting settings like Daytime Running Light location, enabling or disabling halo lights, keeping your fog lights on with your DRLs, and much more!
