ProCal SNAP module for the 2019-2024 HD Ram (incl. 4500/5500) is a simple, cost effective calibration module that will accurately correct your speedometer after installing larger tires (up to 42" tall) and/or changing the axle/transfer case gear ratio, saving you from the headaches of going to the dealership or purchasing unnecessary equipment. The AEV ProCal SNAP Module for Ram 2500/3500/4500/5500 even has the ability to adjust your TPMS threshold, a very important feature to have when running larger tires with less air pressure.

After installing AEV's Programming Harness (included), ProCal SNAP simply plugs into your vehicle's OBDII diagnostic port and interfaces with the user through the audio system equalizer. After inputting the necessary numerical values for the tire size or gear ratio through the audio equalizer (example: 35.5" tall tire = bass 3, mid 5 and treble 5) the settings are saved by pressing and holding a combination of buttons on the steering wheel. It's that easy - in fact, some might say it's a SNAP!

AEV ProCal SNAP is proudly manufactured in the USA.

Did exactly what i needed. To access green plug pop the headlight panel off and its sits right behind that for easier access.

Works exactly as advertised! Speedometer is spot on with 37’s and all functions work as they should. Highly recommend!

Very easy to install, but i had a hard time getting it to work on my 2023 Ram 2500 diesel. Once it started working, worked like a charm. Was able to input my new tire size and iO could tell a difference right away. I would definitely recommend.

What is the wiring harness for?

James H.

2019-2024 Ram trucks have a security gateway module installed from the factory. In order to bypass the security gateway module, there are two options: install a bypass module or install the AEV Programming harness. Its much easier to install the harness which gives enthusiasts a direct connection to their vehicles communication system for the ProCal or any device utilizing the OBDII Connector with the AEV adapter. This system retains the factory security gateway module to protect you from a remote attack through the radio or cellular connection.

What functions will the ProCal SNAP perform?

The ProCal SNAP provides quick and easy speedometer calibration for customers who install taller than stock tires, change their axle/transfer case gear ratio and TPMS threshold adjustment (down to 24 psi).

Can I use the AEV ProCal on more than one vehicle?

James H.

No, the ProCal SNAP pairs itself with the first vehicle it is used on. Do not pair the ProCal SNAP on any vehicle you do not intend on calibrating.

Will the ESP in my vehicle system be affected?

James H.

Yes, for the better. The ESP system uses vehicle speed along with individual sensors that measure acceleration both front-to-rear and side-to-side. ESP functions by calculating how much steering angle the user inputs and how fast the vehicle is going, and then calculates how much side-to-side acceleration should occur. If the side-to-side acceleration is less than what the ESP predicts, that means the vehicle is sliding and it will try to correct the situation by applying specific brakes at each wheel and/or reducing throttle. If the tire size and gear ratio values are incorrect, the calculations the ESP system processes will also be incorrect. This can cause the ESP system to trigger at the wrong time, which at best can be annoying and if it happens at the wrong time (or doesnt happen when it should) can be dangerous. Lifted vehicles are more prone to inadvertent ESP activation, because the speedometer is wrong. The ProCal SNAP will allow you to fix this issue so your ESP can function properly.
