Fits select 2018-2022 Chrysler, Dodge, Jeep, and Ram vehicles equipped with a Security Gateway.

The Z Automotive Z_SGW Security Gateway (SGW) Bypass Module is an essential component for owners of late-model Stellantis vehicles who want to unlock full diagnostic and programming capabilities. Starting in 2018, many vehicles were equipped with a Security Gateway module that prevents aftermarket scan tools and programmers from writing data or making changes to the vehicle via the OBDII port.

This bypass module restores full bidirectional communication by plugging directly into the factory SGW harness. This allows aftermarket devices like the Tazer programmer, diagnostic scanners, and flash tuners to function as intended. It is a necessary addition for any DIY maintenance, custom programming, or when using a Tazer to unlock performance features.

• Manufacturer Part Number: Z_SGW
• Enables full write access through the factory OBDII port
• Required for Tazer functionality on 2018-2022 models
• Simple plug-and-play installation into the factory harness
• Compatible with aftermarket scan tools and tuning devices

Fits select 2005-2010 Chrysler 300, 2008-2014 Dodge Challenger, and 2006-2010 Dodge Charger.

The Tazer No ESP Traction Control Module (MPN: Z_NOESP) allows enthusiasts to fully disable the Electronic Stability Program and traction control on their vehicle. This module is essential for performance driving, drag racing, or track events where factory computer intervention limits power delivery and slide control. By overriding the factory settings, it provides the driver with raw control over the vehicle's handling characteristics without interference from the stability management system.

• Enables full ESP and traction control disablement for track use
• Compatible with 2005-2014 Chrysler and Dodge LX/LC platforms
• Allows for unhindered power delivery during performance maneuvers
• Manufacturer Part Number: Z_NOESP

Fits 2015-2021 Dodge Challenger and Charger models equipped with factory Active Exhaust Systems (AES).

The Tazer Inactive Exhaust Module Kit is a technical solution for owners installing aftermarket exhaust systems that lack mounting points for factory active exhaust actuators. In stock configuration, removing or disconnecting these actuators triggers a Check Engine Light (CEL) and can force the vehicle into a limited-performance mode. This electronic bypass kit plugs directly into the factory wiring harness to simulate the presence of functioning actuators, allowing you to run any exhaust setup without electronic interference.

• Eliminates "Active Exhaust" dash errors and persistent CELs
• Prevents the ECU from entering limp mode due to missing exhaust valves
• Direct plug-and-play installation into the OEM actuator harness
• Compact, moisture-resistant electronic modules for long-term durability
• Reversible installation with no cutting or splicing of factory wiring required
• Manufacturer Part Number: Z_AES_DELETE

The HKS Type 2 Speed Limit Defencer (SLD) is a specialized electronic bypass module designed to eliminate the factory-programmed speed limiter. This device intercepts the speed sensor signal and prevents the ECU from triggering a speed cut, allowing the vehicle to reach its true mechanical top speed during track or closed-course competition.

The Type 2 SLD is specifically engineered to handle complex speed signals where a standard bypass might otherwise interfere with automatic transmission shift points or critical engine management functions. It provides a reliable solution for drivers looking to maximize their vehicle's performance envelope while maintaining the integrity of the factory electronic systems.

• Eliminates OEM speed restrictions for high-speed performance
• Maintains proper ECU signal integrity to prevent electronic interference
• Compact electronic module designed for discreet installation
• Engineered for vehicles utilizing Type 2 digital speed signals
• Manufacturer Part Number: 4502-RA003

The HKS Speed Limit Defencer (SLD) Type 1 is a specialized electronic integration module designed to bypass factory-imposed speed governors. This is a critical component for JDM vehicles or track-oriented builds where the ECU is programmed to initiate a fuel or ignition cut at a specific top speed (typically 180 km/h on Japanese market vehicles).

By intercepting and modifying the speed sensor signal before it reaches the ECU, the SLD Type 1 prevents the vehicle from entering speed-limiting safety modes while allowing the factory speedometer to remain fully operational. This unit is specifically engineered for vehicles that utilize a standard electronic speed pulse signal.

• Eliminates factory speed limiters for unrestricted track performance
• Maintains factory speedometer and odometer accuracy
• Compact electronic module for clean, concealed installation
• Designed for vehicles with standard speed pulse signals
• Manufacturer Part Number: 4502-RA002
