AEV ProCal SNAP for JL Wrangler and JT Gladiator
AEV ProCal SNAP for Jeep Wrangler JL and Gladiator is a cost-effective calibration module that accurately corrects your speedometer after installing larger tires (up to 42" tall) and/or changing the axle or transfer case gear ratio.
It also allows you to adjust TPMS (Tire Pressure Monitoring System) settings, 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, the settings are saved by pressing and holding a combination of buttons on the steering wheel. It's that easy — some might say it's a SNAP!
Key Features: Corrects speedometer for tire sizes up to 42". TPMS adjustment. Programming harness included. Compatible with JL Wrangler and JT Gladiator. Proudly manufactured in the USA.
