NoLimitz Performance & Security System

Take Control of Your Vehicle. Unlock Performance. Add Advanced Security.

The NoLimitz system brings an entirely new level of performance customization and vehicle protection to your vehicle. Designed to work with your factory electronics, NoLimitz gives you access to advanced controls, customizable driving features, and innovative anti-theft technology — all without permanently modifying your vehicle.

Control everything directly through your factory steering wheel buttons and dashboard display. No additional screens, complicated controls, or permanent vehicle modifications required.

Whether you're looking to customize performance, fine-tune vehicle response, or add another layer of theft protection, NoLimitz puts you in control.

PERFORMANCE & CUSTOMIZATION

Steering Wheel Integration

Navigate NoLimitz menus directly through your factory steering wheel controls. View settings and options right on your vehicle's dashboard display for convenient, seamless operation without additional devices or screens.

Remove the Factory Speed Limiter

Customize your vehicle's speed limiter from 0 to 200 MPH, giving you control beyond the factory-set restrictions.

Adjustable Torque Management

Take control of torque delivery with adjustable settings ranging from 0% to 100%. Choose to retain factory ABS-based torque management, disable it, or customize engine torque output to suit your preferences.

Disable MDS

Turn the Multi-Displacement System (MDS) on or off whenever you choose. Keep all eight cylinders operating instead of switching to four-cylinder mode, eliminating unwanted MDS-related exhaust drone and reducing unnecessary cylinder deactivation.

Neutral RPM Limiter Adjustment

Remove the factory 4,000 RPM neutral rev restriction and allow the engine to rev up to its programmed RPM limiter.

Hyper Mode

Experience a more immediate throttle response with Hyper Mode. Designed for drivers who want a quicker, more responsive feel when accelerating.

Available on Scat Pack and Hellcat models only.

Is Tuned Mode

A discreet feature designed to help manage certain tuning-related indicators within your vehicle's control modules. For vehicles with aftermarket PCM tuning, this feature helps manage the recording of certain tuning flags.

Top Speed Display

Keep track of your vehicle's highest recorded speed. View your personal best and reset the reading whenever you want.

ADVANCED VEHICLE SECURITY

More Than Performance. Protection You Can Count On.

NoLimitz takes vehicle security to another level with innovative, patent-pending anti-theft technology. Designed to help prevent unauthorized access, key programming, vehicle movement, and tampering, NoLimitz provides multiple layers of protection to help keep your vehicle where it belongs.

RF Hub Protection

Block unauthorized access to your vehicle's RF Hub to help prevent thieves from programming additional keys and driving away with your vehicle.

Brake Lock

If a theft attempt or unauthorized tampering is detected, Brake Lock can engage all four brakes, even when the vehicle is turned off. This prevents the vehicle from being shifted into neutral and rolled away, making unauthorized movement extremely difficult.

Tamper Detection

Monitor for suspicious activity, including unauthorized key programming attempts or factory alarm triggers. When tampering is detected, NoLimitz can automatically activate your configured security features and initiate lockdown.

No Start

Prevent the engine from starting while security lockdown is active — even when the correct key is present. Enter your personal security code to restore normal vehicle operation.

No Torque

Disable engine torque while lockdown is active. Even if the engine is running, including during remote start, pressing the accelerator will not deliver power to move the vehicle. Normal operation is restored after entering your security code.

Panic Mode

Automatically activate the factory panic function when tampering is detected. The horn sounds and hazard lights flash to attract attention and discourage potential thieves.

Light Show

When a compatible Tazer device is detected, this feature can activate a vehicle light show during a security event. Flashing lights help draw attention to the vehicle when lockdown is triggered.

Lock Mode

Choose the security operation that works best for your needs:

• Off: Disables automatic lockdown.

• Auto: Automatically places the vehicle into lockdown until your personal security code is entered.

• Igla: Provides compatibility with an Igla security system.

• Tazer: Provides compatibility with a Tazer device.

These options allow you to configure NoLimitz to work alongside other security solutions for additional protection.

Run Lock

Quickly switch Lock Mode between Auto and Off without navigating through multiple menus. Activate additional protection when needed and conveniently return to your preferred setting.

Quick Lock

Leaving your vehicle running for a quick stop? Activate Quick Lock with a steering wheel button as you exit. The system engages the brakes and disables accelerator response to help prevent someone from driving away while the engine is running. Enter your security code to restore normal operation.

Quick Valet

Handing your keys to a valet? Activate Quick Valet as you exit and automatically engage your preset speed and torque restrictions. Your vehicle remains in Valet Mode until your personal security code is entered.

Custom Security Code

Create your own four-entry security code using your factory steering wheel buttons. The default combination uses the cruise control buttons (Up, Down, Right, Left), but you can customize your code using available steering wheel controls, including paddle shifters.

TEEN & VALET MODE

Set the Limits. Stay in Control.

Whether you're handing your vehicle to a valet, allowing a younger driver behind the wheel, or simply want to limit vehicle performance, the NoLimitz Teen/Valet menu gives you control over how your vehicle is driven.

Enable Teen/Valet Mode

Activate Teen/Valet Mode directly through the menu or use the convenient Quick Valet shortcut when handing over your keys.

Adjustable Maximum Speed

Set a maximum vehicle speed limit to help ensure your vehicle stays within the speed range you've selected.

Adjustable Maximum Torque

Customize engine torque output from 0% to 100% while Teen/Valet Mode is active. Limit available power for additional control when someone else is driving your vehicle.

SIMPLE PLUG-AND-PLAY INSTALLATION

NoLimitz is designed for a straightforward installation using your vehicle's factory wiring connections.

• Connects directly to factory harnesses.

• No cutting or splicing of factory wiring.

• No permanent vehicle modifications required.

• Designed to be removed without leaving physical wiring alterations behind.

Enjoy advanced performance and security features without making permanent changes to your vehicle's factory wiring.

NON-INTRUSIVE OPERATION

NoLimitz operates through your vehicle's existing electronic systems without requiring permanent ECU reprogramming. Its removable design allows you to return your vehicle to its original configuration when the device is removed.

The manufacturer states that the system does not trigger dealer tool alerts or void your factory warranty. Warranty coverage and dealer detection can depend on vehicle, installation, and applicable manufacturer policies, so customers should verify these details before installation.
