AEV's ProCal Module is a hand-held powerhouse! This essential tool provides JK owners 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 is the ability to correct the speedometer and gear ratio when larger tires are installed. With the speedometer 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. Further, 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 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.

  • 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
    Note: Lowering a vehicle's tire pressure below that specified by the vehicle/tire manufacturer may create unsafe handling characteristics. AEV assumes no responsibility for a vehicle's handling characteristics or the safety of the vehicle's occupants.

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.

I ordered a procal for my Jeep. USPS lost the package. I made a case with them then out of courtesy advised 4WS. They immediately sent another one via UPS and I received it within 2 days. They were very helpful and although the lost one was not their fault, they made sure I received my package. I finally received the original box 1.5 weeks later and sent it back to 4WS.

Great service. I'll definitely order here again.

Great to have control over the JK. But I don't understand why I have to have one for each vehicle. This is why I down rated the value. Review by Jeeper Creeper (Posted on 6/4/2015)

This programmer is a must have for any JK owner. Gives you control over your vehicle that even the dealership doesn't want you to have.

Many features, but I love turning my headlights or front turn signal lights into daytime running lights.

Lets you program your actual tire size in so your shift points are where they belong, your speedo is correct, and your fuel computer calculates more accurately.

For the low price, its a must have.
