🧾 Overview
The Z Automotive No Limitz Module is a plug-and-play performance override module for Jeep Wrangler JL and Gladiator JT, designed to remove factory-imposed limitations and unlock the vehicle’s full potential.
This module allows you to disable factory speed limiters, torque management, and 4LO restrictions, giving you full control over throttle response and performance—especially useful for modified Jeeps running larger tires or built for off-road use.
Unlike traditional tuners, the No Limitz system does not require PCM unlocking or permanent changes, making it fully reversible and safe for warranty concerns. It also adds a layer of theft prevention by blocking RF hub access, which is a known vulnerability on newer Jeeps.
