AEV's ProCal Module for 2013+ 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 are installed. When the speedometer is left uncorrected, there is a major degradation in the performance of the stability control (ESP), transmission shifting hence poor drive ability – the ProCal Module will correct these issues by ensuring that the vehicle is properly calibrated to OE specs.
Additionally, the ProCal Module is the only product of its kind that allows the user to re-calibrate 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 process has 2 stages – 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. This is stage 1 - after that you will need a dealer to use WiTek to go into the back end of the computer and accept the changes. Murchison Products offer this service in house as will SCD, Trucks and Toys and Maracoonda that we know of. We have also sent these units to ATECO dealers with no problems.
A visit to your local Jeep Dealership, or Murchison Products Workshop and use of the WiTech diagnostic tool is required to complete this procedure. Although your TPMS screen will show the new values, it will not “take” and stop blinking until your dealership completes the process.
