The JKS J-Cal is loaded the Flashcal with the most sought after options JK consumers want. The J-Cal makes it possible to activate daytime running lamps, "one-touch" lane changes, enable a temporarily increased engine idle speed for winching, clear engine codes. The J-Cal also gives you the ability to correct the speedometer for gear and axle swaps and when larger tires are installed. With the speedometer left uncorrected, there is a major degradation in the performance of the stability control (ESP), transmission shifting, and engine performance. J-Cal can only be updated on Windows 7 or higher.
