JB4 SENT Tuner – Plug-and-Play Performance for Audi B9 and Porsche Turbo Vehicles
The JB4 SENT Tuner is the ultimate performance upgrade for turbocharged Audi and Porsche vehicles, including B9 S4, S5, SQ5, RS4, RS5, and select Porsche Macan S and Cayenne models. This plug-and-play tuner integrates directly with your factory ECU to safely remap boost, timing, and fueling, delivering faster 0-60 times, improved quarter-mile performance, and reduced turbo lag.
Advanced SENT Sensor Technology & CANbus Integration
The JB4 SENT includes full SENT sensor technology, essential for tuning the latest Audi platforms. With complete CANbus integration, the tuner monitors all engine parameters in real-time and incorporates safety protocols such as:
- Reducing boost until oil and coolant reach optimal temperature
- Switching to a low-boost map if the engine overheats, runs lean, over-boosts, or detects knock
- Fuel control for ethanol mixture mapping
Revision 2 now features an integrated boost control connection for high-power applications—eliminating the need for a separate BCM module.
Wireless JB4PRO Connectivity
The included JB4PRO adapter allows seamless wireless connection to iOS or Android devices via Bluetooth 4.0. This app enables:
- Real-time data logging and vehicle performance analysis
- Switching between performance maps on the fly
- Firmware updates with new maps, features, and improvements
- Advanced diagnostic and performance estimation tools
The adapter fits entirely inside the JB4 enclosure, providing enhanced weather protection and a clean, streamlined appearance.
