ProCal SNAP for JL Wrangler and Gladiator truck is the latest addition to AEV’s growing family of electronic calibration modules. This cost effective calibration module will accurately correct your speedometer after installing larger tires and/or changing the axle/transfer case gear ratio, saving you from the headaches of going to the dealership or depending on a lesser quality module.   

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!

ProCal SNAP is proudly manufactured in the USA.

ProCal SNAP is included with AEV JL suspension systems!

 

FAQS

What is the wiring harness for?

The JL Wrangler and Gladiator both 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. It’s 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.
 

There are other similar electronic calibration modules on the market, what makes the ProCal SNAP better?

Experience- AEV have been designing and manufacturing calibration modules for over a decade, beginning with the JK Wrangler. Also, we have tested some of the competitive products out in the market and have seen everything from unexplained battery draw to features that are potentially dangerous to both the user and the vehicle.

For customers looking for additional features, AEV are currently working on the development of a next generation ProCal module that will offer even more options than any other module they have previously released.
 

What functions will the ProCal SNAP perform?

The ProCal SNAP provides quick and easy speedometer calibration for customers who install taller than stock tires or change their axle/transfer case gear ratio.
 

Will the ESP in my vehicle system be affected?

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 doesn’t 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.
 

I bought 35" tall tires, do I really have to measure them or is 35" close enough?

Yes, you really have to measure the tire. The size listed on the side of the tire can be off by as much as an inch in either direction. All manufacturers’ values are different, and there can be variation in the manufacturing process. An actual measurement with weight on the vehicle, rounded to the nearest quarter inch, is required in order to get an accurate input.
 

We use the metric system in Australia, will the ProCal SNAP work for me?

No problem. Since the ProCal SNAP is primarily marketed in the United States, the instructions show non-metric values. Simply convert your metric values to imperial and follow the instructions provided.
