Hand-Held Powerhouse for your Jeep If you've installed a lift kit or upgraded to larger tires and wheels, your Jeep's computer will probably need to be re-calibrated to ensure proper and consistent performance.
The AEV ProCal Module is an essential tool to provide JK owners with an easy and low-cost way to make various useful changes not offered by the dealer or other re-programmers. Topping the list 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 decline in the performance of stability control, transmission shifting, and overall engine performance. Better yet, this module can even help clear your engine codes, increase your engine's idle speed, and perfect the overall performance of your Jeep. Re-calibrate your Tire Pressure Monitoring System
Please note:
With manual transmissions, the AEV ProCal cannot change axle gear ratios for 2011+ 2.8L CRD diesel JK Wranglers. The RESTORE function is incompatible with export JK’s with the 2.8L CRD engine.

Easy to use. I used it to reprogram the computer for larger tires. It allowed the computer to re-adjust the shift point and now my jeep drives much better.
After looking at all the options in this price range the Procal was the best choice for me. It does everything I need, is very easy to use. No issues. No downloading anything. Definitely recommend.
I saw your video about the procal, can I use it to change my gear ratio from 3.71 to 4.56 with the same size tires I've had (285/75r16)? I did not change tire size when upgrading gears.
