Description
Enhance the performance of your 2017+ Porsche Carrera, Carrera S, and GTS models with the JB4 Performance Tuner, the most advanced plug-and-play tuning solution for modern Porsche turbocharged engines. Delivering up to 40 horsepower and 60 lb-ft of torque at the wheels on a stock vehicle, the JB4 improves acceleration, throttle response, and overall driving dynamics while maintaining factory reliability and safety systems.
Designed specifically for the latest Porsche platforms, the JB4 features advanced SENT (Single Edge Nibble Transmission) sensor technology, ensuring precise integration with factory electronics. The system connects directly to engine bay sensors and works alongside your ECU to remap boost, timing, and fueling for optimal performance and reduced turbo lag—without requiring an ECU flash.
Advanced CANbus Integration & Intelligent Safety
With full CANbus integration, the JB4 continuously monitors critical engine data such as air/fuel ratios, ignition timing, boost pressure, and knock activity. It uses this data to apply dynamic tuning strategies while incorporating advanced safety features, including:
- Controlled boost ramp-up until optimal oil and coolant temperatures are reached
- Automatic low-boost mapping during overheating, lean conditions, or excessive knock
- Overboost protection to safeguard engine components
- Ethanol (E85) fuel mapping support for increased performance flexibility
Wireless JB4PRO Connectivity
Included with the system is the JB4PRO Bluetooth adapter and free smartphone app, allowing seamless wireless control from iOS and Android devices. With the JB4PRO app, you can:
- Switch between multiple performance maps for different fuels and driving conditions
- Monitor and log up to 40 engine parameters in real time
- Analyze performance data and identify tuning adjustments
- Receive free firmware updates with enhanced features and improved performance
The adapter is integrated داخل the JB4 enclosure for improved durability and a clean, factory-style appearance.
