The Tazer is an OBD2 plug-in device that can “speak” to your car via CAN communication busses. It can change the car’s configuration to add or unlock features, as well as provide some “live” features by sending commands to modules. These commands, typically sent by a dealer scan tool, are not harmful to the vehicle.

The USB port serves two purposes:

  • Configuration: Using the ZPU programming utility, you can change light show settings. More configuration options may be added in the future.
  • Updates: Z Automotive is constantly improving the Tazer and adding new features. Firmware updates, when available, can be installed via USB using the ZPU utility.

The Magnusson-Moss Warranty Act (1975) states a manufacturer can deny a warranty claim only if they prove that an aftermarket component caused the failure. To be safe, write down the settings you’ve changed with the Tazer and revert them to their original values before servicing. "Live" features like light shows, line lock, full ESP disable, nav in motion, and force video usage cannot be detected.

Yes. The Tazer is designed to enter sleep mode 30 seconds after the car’s accessory power shuts down. It can remain plugged in full-time. If you aren’t planning to use features like line lock, light shows, full ESP off, force RWD/AWD, nav in motion, or force video, feel free to leave it connected as you like.

No. The AWD system is designed to keep the front axle disconnected most of the time, engaging it only as needed (e.g., during wheelspin, when the temperature drops below 40°F, or when the windshield wipers are on). The Tazer’s Force RWD function simply prevents the front axle from engaging.

The light show is shipped to work only when the car is stationary. Using it on the street may appear as impersonating a police officer, which is a felony. However, the light show can be enabled for in-motion use through a hidden menu in the ZPU programming utility. If you want to unlock this feature and take responsibility for its usage, contact tech support for instructions.
  • Scat Pack: You won’t have track transmission mode, but you’ll still enjoy increased throttle response and stiffer steering in track mode. Valet mode is also available.
  • 3.6 or 5.7 engines: You can’t access SRT drive modes but can still use other features.
  • SRT 392 or Hellcat: These already have SRT drive modes, but you can still benefit from Line Lock, light shows, nav in motion, and more.
  • Scat Pack with SRT modes: In Track mode, the traction setting won’t change to "Track" because of the lack of adaptive suspension. However, you can still use other Track mode features with traction in Street, Sport, or OFF.
  • 2016 Scat Pack: The "Sport" button near the Super Track Pack button won’t work after enabling SRT mode. Double-clicking the Super Track Pack button will still activate Custom mode.
  • Startup logo: Enabling SRT mode on Scat Packs with the "Bee" logo changes the startup logo to the standard SRT Charger/Challenger logo. Disabling SRT restores the Bee logo.
  • 2015/2016 Chargers (3.6/5.7): Enabling SRT mode causes an airbag error. SRT mode doesn’t provide benefits for these cars, though you can still access EVIC performance pages and Sport mode if not already present.
  • 2015/2016 Challengers (3.6/5.7): No airbag error occurs, but the UConnect system will think you have a Hellcat, making Sport, Track, and Valet modes inaccessible.

Performance Pages functionality depends on the car:

  • 2011 Charger: Not available.
  • 2012–2014 Charger/300 with 8.4" Uconnect: Supported.
  • 2015/2016 Charger/Challenger: Rarely works unless the radio has been upgraded.
  • 2017 models: Supported.
  • Dodge Durango, Jeep Grand Cherokee, RAM: Not compatible.
