AEV ProCal Module

The AEV ProCal Module allows you to make a variety of useful changes to your Wrangler JK that are not offered by the dealer or any other re-programmer. It gives you the ability to correct the speedometer and gear ratio when larger tires are installed. This is especially useful because when the speedometer is left uncorrected there is a major degradation in the performance of the stability control (ESP), transmission shifting, and overall engine performance. The Tire Pressure Monitoring System can also be re-calibrated to better suit aftermarket tires without triggering the dash light. This module can also activate daytime running lamps, allow for "one-touch" turn signals, clear engine codes, enable a temporarily increased engine idle speed for winching, and can help alignment technicians align the vehicle perfectly for optimal ESP performance. It is equipped with a series of easy-to-use DIP switches that can be set before plugging the module into your Jeep's OBDII. The included Quick Reference Guide has all of the codes for desired re-calibration. It takes only minutes to complete the entire process and is just as easy to restore the vehicle back to its original settings.
