JKS Jeep JK J-Cal Programmer
JKS J-Cal Programmer is an essential tool that provides JK owners an easy, low-cost way to make a variety of useful changes not offered by the dealer or any other re-programmer. Topping the list is the ability to correct the speedometer and gear ratio when larger tires are installed. When the speedometer is left uncorrected, there is a major degradation in the performance of the stability control (ESP), transmission shifting, and engine performance.
The best part of the J-Cal is that it isn’t just for correcting the speedometer. The Tire Pressure Monitoring System can now be recalibrated to better suit aftermarket tires without triggering the dash light. Further, the J-Cal Programmer makes it possible to activate daytime running lamps, “one-touch” turn signals, enable a temporarily increased engine idle speed for winching, clear engine codes, and even has a feature to help alignment technicians align the vehicle perfectly for optimal ESP performance.
The J-Cal Programmer is equipped with a series of easy-to-use controls right on the programmer. A user can quickly dial in a code for the desired recalibration. Once the DIP switches are set, simply plug the Programmer into the vehicle's OBDII. The whole process can be completed in mere minutes and it's just as easy to restore the vehicle back to its original settings.
