AEV ProCal Tuner Module





Pin It Fancy

Product Description:


  • Gain the ability to quickly and easily:
  • re-calibrate speedometer
  • re-calibrate TPMS pre programmed air pressure settings
  • program daytime running lights settings
  • control idle speed for winching
  • clear engine codes
  • Provides JK owners an easy, low-cost way to make a variety of changes not offered by the dealer or any other re-programmer.
  • 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 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.
  • 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 performance.
  • 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.
  • 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 (w/ A580 trans) 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 number 30406007AG). As of 2/18, all ProCal Modules being shipped from AEV are the latest version and include this function.

  • Clear engine codes
  • Easy to use DIP switches

    Revisions:

    Due to updates in vehicle electronic systems and the existing code on inventory, some Procal modules were made before the changes required for newer vehicles. Please take a look at the part number on the module itself (not the box), there should be a white sticker with a part number, the last two letters of that part number are the revision.

    AA/AB/AC – Works from 2007 up to 2011 (these early Procals may not have a label, if your Procal does not have a part number it is likely an AA, AB, or AC)

    AD/AE/AF/AG – Works up to 2014
