A Jeep is built for adventure, but many owners want more control over how their vehicle behaves. This is where the Tazer for Jeep comes in.
If you’ve heard of this device but aren’t sure what it does, you’re not alone. The Tazer is a small electronic tool that unlocks hidden features in your Jeep and allows you to change factory settings.
Whether you want to adjust your tire size, turn off annoying lights, or enable special functions, the Tazer offers a powerful way to customize your ride.
What Is A Tazer For Jeep?
The Tazer is a plug-and-play programmer designed mainly for Jeep Wranglers (JK, JL) and Gladiators (JT). Made by Z Automotive, it connects to your Jeep’s OBD-II port—no tools, no permanent changes. Once plugged in, it communicates with your Jeep’s computer to change factory settings and activate features that are usually locked.
Think of the Tazer as a remote control for your Jeep’s brain. It lets you:
- Change settings like tire size or gear ratio
- Enable or disable certain lights and chimes
- Activate “light shows” or special functions
- Read and clear error codes
With a Tazer, you can make your Jeep truly your own without needing to visit a dealership or use expensive software.
Key Features And Functions
The Tazer is popular because it delivers a long list of features that can enhance both daily driving and off-road adventures. Here are some of the most important:
- Tire Size Adjustment: If you install larger tires, your speedometer and odometer will be incorrect. The Tazer lets you enter the new tire size so your Jeep’s computer recalculates speed and mileage.
- Gear Ratio Changes: After installing new axles or changing gear ratios, the Tazer updates your Jeep’s settings. This keeps the transmission and traction control working correctly.
- Light Shows and Custom Lighting: The Tazer can control your Jeep’s lights in unique patterns. Some people use this for car shows or parades.
- TPMS Settings: The Tire Pressure Monitoring System (TPMS) can be annoying if you run lower tire pressure off-road. The Tazer allows you to adjust or even turn off these warnings.
- Disable Auto Start/Stop: Many Jeep owners dislike the automatic engine start/stop feature. The Tazer allows you to turn it off for good.
- Sway Bar and Locker Control: For Rubicon models, you can control the sway bar and axle lockers even in 2WD or high speeds, which is usually not possible.
- Read and Clear DTCs: The Tazer works as a code reader, helping you diagnose problems and clear error codes.
Here’s a quick comparison of what the Tazer can change:
| Feature | Factory Control | Tazer Control |
|---|---|---|
| Tire Size | No | Yes |
| Light Shows | No | Yes |
| TPMS Settings | No | Yes |
| Auto Start/Stop | No | Yes |
These options give you more control over your Jeep’s behavior and allow for simple personalization.
How Does The Tazer Work?
The Tazer is designed for easy use, even for beginners. Here’s how it works:
- Plug In: Connect the Tazer to your Jeep’s OBD-II port under the dashboard.
- Select Settings: Use steering wheel buttons to scroll through menus on your dash.
- Make Changes: Follow prompts to update features or settings.
- Unplug (Optional): Some features stay after you unplug the Tazer; others require it to stay connected.
Most changes are safe and can be reversed. For example, if you adjust your tire size, you can always go back to the stock setting.
Benefits Of Using A Tazer
Many Jeep owners find the Tazer to be one of the best upgrades for their vehicle. Here’s why:
- Cost Savings: You can make changes yourself instead of paying a dealer.
- Customization: Unlock unique Jeep features that are hidden from the factory.
- Simplicity: No special skills or tools are needed.
- Resale Value: You can return all settings to stock before selling your Jeep.
A surprising benefit is the Tazer’s ability to “marry” to your vehicle. This means it stores your original settings so you can always restore them if needed.
Limitations And Considerations
While the Tazer is powerful, it’s not perfect for every situation. Here are some things to keep in mind:
- Warranty Concerns: Some dealers may question warranty claims if non-factory settings are used.
- Compatibility: Not all Tazer models work with every Jeep. Always check your model/year before buying.
- Learning Curve: The menu system is simple, but some features may take time to understand.
- Updates: Make sure to use the latest firmware for best results.
Here’s a quick guide to Tazer compatibility:
| Jeep Model | Supported Tazer Version |
|---|---|
| Wrangler JK (2007–2018) | Tazer JK |
| Wrangler JL (2018+) | Tazer JL Mini/Full |
| Gladiator JT (2020+) | Tazer JL Mini/Full |
If you plan to use a Tazer on a newer Jeep, make sure it supports your exact trim and year.
Common Mistakes And How To Avoid Them
- Not Saving Original Settings: Always back up your stock settings before making changes.
- Using the Wrong Tazer Model: Double-check that the Tazer you buy matches your Jeep.
- Forgetting to Unmarry: If you sell your Jeep, remember to restore the original settings and “unmarry” the device. Otherwise, it won’t work on another vehicle.
- Ignoring Software Updates: Regularly check for new Tazer firmware. Updates can add features and fix bugs.
- Over-customizing: Too many changes at once can make it hard to troubleshoot if something goes wrong. Take it step by step.
Real-world Examples
Many Jeep owners share their Tazer stories online. One driver used it to correct the speedometer after upgrading to 35” tires, saving hundreds in dealer fees. Another used the light show feature at a local parade, drawing cheers from the crowd.
These personal touches are what make owning a Jeep and a Tazer so rewarding.
