The Double-Bypass is a security gateway bypass for the TaZer Programmer by Z Automotive.
The Double-Bypass is required on all 2018+ Dodge/Chrysler/Jeep to overcome the security module that renders the OBD2 port inoperable for all aftermarket devices and tuners. The Double Bypass kit overcomes this obstacle by installing a secondary OBD2 port in the trunk, bypassing the security module.
The Double Bypass will also work on 2011-2017 Chargers/300s and 2015-2017 Challengers, for those that want to relocate their Z Automotive devices to the trunk, freeing up the factory OBD2 port for other tuning devices.
