Description
The Burger Tuning Group 7 JB4 SENT Tuner is the most advanced plug-and-play tuning system available for the latest Audi and Porsche turbocharged platforms. Designed with full SENT sensor technology for proper communication with modern Audi ECUs, this JB4 integrates seamlessly with factory electronics to safely deliver maximum horsepower and torque gains while maintaining OEM-like drivability.
With CANbus OBDII integration, the JB4 can access real-time engine data and apply advanced tuning strategies, including boost-by-gear control, ethanol fuel mapping, and multiple built-in safety systems such as boost limiting until optimal oil/water temperatures are reached. It will automatically drop to a safe map if overheating, excessive knock, or overboost is detected.
Revision 2 now features an integrated boost control connection — no need for a separate BCM module — enabling even greater performance potential for higher power setups.
Installation is quick and completely reversible with no ECU flash required, making it ideal for leased vehicles or those looking to maintain warranty flexibility.

What is a JB4?
The JB4 is a next-generation piggyback tuning system that installs between your car’s sensors and ECU (DME) to optimize performance parameters such as boost, fueling, and ignition timing. Unlike basic performance chips, the JB4 integrates with CANbus for real-time engine monitoring, multiple safety protocols, wireless tuning control, and ongoing free firmware updates. It is not VIN locked, meaning it can be removed without a trace or transferred to another compatible vehicle.
