AEVAEV ProCal Module for 2007-2018 Wrangler JK

The AEV Jeep JK ProCal Module is a handheld powerhouse for those who want to customize and optimize their vehicle. This essential tool provides JK owners with 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 of AEV ProCal Jeep JK tasks 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 stability control (ESP), transmission shifting and engine performance. All that is on top of not getting accurate information about your speed, vehicle mileage and fuel efficiency. By pressing a few buttons, you can adapt the speedometer and gearing to your new tire size, letting you get the most from those aftermarket shoes.

Other ProCal Jeep JK Functions

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, use "one-touch" turn signals, clear engine codes and enable a temporarily increased engine idle speed for winching. It even has a feature to help alignment technicians align the vehicle perfectly for optimal ESP performance.

The ProCal Module is equipped with a series of easy-to-use DIP switches. By reading the 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 to its original settings with the ProCal.

This module is one of the best Jeep JK accessories for fast, easy optimization. When you order it from Just for Jeeps, you'll get it at a price other dealers can't or won't match.

Key Features:

  • Correct speedometer
  • "One touch" turn signals
  • Clear engine codes
  • Easy-to-use DIP switches
  • Recalibrate tire pressure monitor
  • Increase engine idle speed
  • Optimize ESP performance
  • Transfer case calibration (2012+ JK Wrangler with A580 transmission)

Please note:

  • The AEV ProCal will enable axle gear ratio changes to be made to Wranglers equipped with the A580 Automatic transmission (2011+ 2.8L, 2012+ 3.6L).
  • The AEV ProCal cannot change axle gear ratios for 2011+ 2.8L CRD diesel Wranglers with manual transmissions.
  • AEV's ProCal Module now features an all-new Transfer Case Calibration function that allows customers to install a non-stock transfer case into their 2012+ JK Wrangler (with A580 transmission) without causing the vehicle to go into limp mode. This includes 2-speed Atlas transfer cases as well as Chrysler's Command-Trac NV241 (Sport/Sahara) and Rock-Trac NV241 (Rubicon) transfer cases. This new feature is only found on the latest version of the ProCal Module (part #30406007AG). All ProCal Modules being shipped from AEV are the latest version and include this function.
