So you've put on larger tires and now the speedometer is off. Shift points seem sluggish. And you have an annoying light now on the dash telling you the tire pressure is not correct. All certainly annoying problems and, if left uncorrected, can lead to a major degradation in stability control (ESP) performance, transmission shifting, and engine performance.
The AEV ProCal Module is the perfect, affordable, solution to these problems, while also making it possible to activate daytime running lamps, provide a one-touch turn signal option, and temporarily increasing engine idle speed for winching. This module can also 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 code card included with the Module, any user can quickly dial in a code for the desired recalibration. From there they simply plug the Module into their vehicle's OBD port and wait for the horn to honk. The whole process can be completed in mere minutes and it's just as easy to reverse.
- Large tire recalibration (Restores the vehicle's speedometer/odometer accuracy following the installation of larger-than-stock tires)
- Axle gear ratio recalibration (Resets automatic transmission shift points to maximize the benefits of an axle gear ratio change)
- Tire Pressure Monitoring System recalibration
- Daytime running lamp activation/deactivation, and lamp location selection
- One-touch turn signal activation/deactivation
- Engine idle speed options (Improves winch performance and battery charging capabilities by temporarily increasing engine idle RPM)
- Steering wheel centering (Provides for spot-on steering alignment)
- Clears Engine Diagnostic Codes
- ROHS Compliant (Meets European Restriction-of-Hazardous-Substance standards)
- Lead and Mercury Free
- Meets or exceeds Bosch CAN 2.0b specifications
- 100% Designed by AEV
- Made in the USA
- Compatible with 2007 and newer Jeep Wranglers equipped with 3.6/3.8L V6, 5.7L or 6.1/6.4L V8, 2 or 4-doors and right or left-hand-drive.
- Once used for recalibration, AEV's ProCal Module stores a vehicle's VIN in its memory. While a VIN is stored in memory, a ProCal Module cannot be used on a second vehicle. To use the ProCal Module on a second vehicle, the first vehicle must be recalibrated to stock. This will clear the first VIN and ready the ProCal Module for use on the second vehicle.
- 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.

AEV ProCal Module Reviews
Works as designed, very easy to use, set the switches and turn the key on and you are set!
Perfect for making some changes that were needed after a lift and tire upgrade! Extremely easy to use and feels like nice quality. Will buy again for another Jeep down the road if needed!
Got what I paid for.
