AEV's ProCal Module for 2013-18 Ram 1500/2500/3500 trucks is a user-friendly recalibration tool that has a variety of unique features. One of the most popular features of the ProCal Module is its ability to correct the speedometer when larger tires (up to 48” tall) 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 ProCal Module will eliminate these issues by ensuring that the vehicle is properly calibrated.
Additionally, the ProCal Module is the only product of its kind that allows the user to recalibrate the TPMS system for larger diameter tires that have a lower inflation pressure than the stock tires – a common scenario that would otherwise lead to an annoying low tire pressure warning light. The ProCal will also recalibrate for axle gear ratio changes, allow users to turn the truck’s one-touch lane change feature on or off and determine whether or not the fog lights turn off or stay on with the high beams (for off-road use only).
The ProCal Module is equipped with a series of easy-to-use DIP switches. By reading the simple instructions included with the ProCal module, the user can quickly dial in a code for the desired recalibration. The entire process can be completed in mere minutes – once the switches are set, simply plug the ProCal Module into the vehicle's OBDII and wait for the horn to honk, confirming that the setting has taken effect.

Easy install of the security bypass for the 2018 Ram. Even easier to follow instructions for programming. The transmission appears to shift smoother after programming the correct tire diameter.
No more TPMS light! Easy set up and programming. My local Ram technician was impressed by what it could do.
The module did everything the website said it would and was super simple to use. Fixed my tire size issue and allowed me to change some of the things that were bothering me on my truck.
