All currently shipping AEV ProCal Modules work up to and include the 2018 JK Wranglers.
AEV's ProCal Module is a hand-held powerhouse! This
essential tool 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
The best part of the ProCal 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 ProCal Module 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
The ProCal Module is equipped with a series of easy-to-use DIP
switches. By reading the simple Quick Reference Guide included with the
ProCal module, a user can quickly dial in a code for the desired
recalibration. Once the DIP switches are set, simply plug the Module
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 with the ProCal.
