The ZAutomotive Tazer JL Mini is a plug-and-play electronic programmer for 2020–2026 Jeep Gladiator JT models that unlocks over 70 vehicle settings and live driving features directly through your dash display. It plugs into the Security Gateway (SGW) module above the OBD2 port and is especially popular for permanently disabling Auto Stop/Start after an aux battery delete and recalibrating the truck for larger tires. ¹⁾²⁾³⁾

ZAutomotive Tazer JL Mini Programmer $334.86 ⁴⁾

• Compatibility: Fits all 2020–2026 Jeep Gladiator JT engines and trims, including 3.6L Gas, EcoDiesel, and export variants.
• Key Advantage: Combines permanent computer recalibration (tires, gears, LED lighting) with real-time trail and convenience functions.
• Community Consensus: Owners on Reddit agree it is a worthwhile upgrade for remembering Auto Stop/Start off settings, fixing speedometer readings for bigger tires, and killing the 3-honk exit alert. ^5)6)7)8)9)

Vehicle Settings (Saved to the Jeep's Computer)

These settings are programmed with the engine off and ignition in the “RUN” position, and they stay active even if you unplug the Tazer.¹⁰⁾

• Tire & Gear Calibration. Adjusts tire size up to 41 inches, updates axle gear ratios, and changes transfer case low ratios so your speedometer and transmission shift points stay accurate. ¹¹⁾¹²⁾
• TPMS Adjustments. Lowers or raises the Tire Pressure Monitoring System warning thresholds between 25 PSI and 85 PSI, or disables the system completely.¹³⁾
• OEM Upgrade Activation. Enables factory add-ons without a dealer visit, including LED headlights/taillights, auxiliary switch banks, trailer brake controllers, and the 115V pickup bed outlet. ¹⁴⁾
• One-Touch Unmarry. Reverts all modified computer settings back to factory stock in one step before dealership service.^{15) 16)}

Live Functions (Active While Plugged In)

These features run continuously while the module stays connected to your Jeep.¹⁷⁾

• Auto Stop/Start Memory. Automatically remembers your last ESS button state so you do not have to press it every time you start the truck.
• Gladiator-Specific Lighting. Turns off the license plate lights automatically when shifting into reverse to eliminate backup camera glare, and lets you turn on the bed and reverse lights from your keyfob.
• Off-Road & Winch Controls. Engages Rubicon/Mojave axle lockers in 2WD and 4Hi on demand, disconnects the sway bar in 2WD up to 30 mph, and raises engine idle up to 2,000 RPM for winching.
• Anti-Theft & Convenience. Adds a steering wheel button PIN lock before driving, disables the three-horn honk when exiting a running Jeep, and activates the backup camera when using turn signals (TurnCAM). ¹⁸⁾

Installation & Dealership Tips

• Plug-In Location. Remove the driver-side knee panel under the steering wheel and locate the two SGW connectors just above the OBD2 port. Unplug both cables from the factory module and snap them directly into the Tazer JL Mini.
• SGW Extension Cable. The factory SGW wires are short and tucked tightly behind the dash. Adding an optional SGW extension cable from ZAutomotive makes unplugging the Tazer before dealer visits much easier.
• Power-Down Cycles. After changing any Vehicle Settings, perform two full sleep cycles (turn ignition off, open and close the driver door, and wait 60+ seconds for the dash screen to go black) so the body control module saves your changes.¹⁹⁾
