The ProCal Module from AEV is a portable powerhouse! This vital tool allows JK owners to make a range of beneficial tweaks that aren’t available through the dealer or any other re-programmer. The ability to fix the speedometer and gear ratio when bigger tyres are added is at the top of the list. The performance of the stability control (ESP), transmission shifting, and engine performance all suffer when the speedometer is not adjusted.
The nicest thing about the ProCal is that it’s not simply for speedometer correction. The Tire Pressure Monitoring System may now be re-calibrated to better fit aftermarket tires without causing the dash light to illuminate. In addition, the ProCal Module enables the activation of daytime running lamps, “one-touch” turn signals, a temporary increase in engine idle speed for winching, the clearing of engine codes, and even a feature that assists alignment technicians in perfectly aligning the vehicle for optimal ESP performance.
A set of easy-to-use DIP switches are included with the ProCal Module. A user may rapidly dial in a code for the required recalibration by reading the short Quick Reference Guide supplied with the ProCal module. Simply insert the Module into the vehicle’s OBDII port once the DIP switches have been configured. The entire procedure takes only a few minutes, and the ProCal makes restoring the car to its original settings a breeze.
- The AEV ProCal will allow axle gear ratio alterations to be done to Wranglers equipped with the A580 automatic transmission (2011-16 2.8L, 2012-17 3.6L)
- The AEV ProCal is unable to alter axle gear ratios for 2017 2.8L CRD diesel Wranglers with standard transmissions.
- The new Transfer Case Calibration option in AEV’s ProCal Module allows customers to install a non-stock transfer case into their 2012-18 JK Wrangler (with A580 trans) without the vehicle going into limp mode. This includes Chrysler’s Command-Trac NV241 (Sport/Sahara) and Rock-Trac NV241 (Rubicon) transfer cases, as well as 2-speed Atlas transfer cases. This new functionality is only available in the ProCal Module’s most recent version (part number 30406007AG). As of 2/18/16, all AEV ProCal Modules are the most recent version and incorporate this feature.
