Description
JB4 Performance Tuner – Ford Taurus SHO (2010–2019)
Maximize the performance of your Ford Taurus SHO with the JB4 Performance Tuner, a cutting-edge plug-and-play solution engineered to deliver up to 100 horsepower and 120 lb-ft of torque to the wheels—all without the risks associated with ECU flashing.
Designed for turbocharged performance enthusiasts, the JB4 enhances boost, ignition timing, and fueling to unlock substantial power gains while maintaining factory safety systems and drivability.
Plug-and-Play Installation
The JB4 installs easily by connecting to two accessible sensors in the engine bay. Unlike ECU flash tunes, the JB4 operates externally, allowing it to be fully removable without leaving a trace. Your vehicle remains unaware of increased boost levels, preserving factory safeguards and reliability.
Fuel economy remains unchanged during normal driving, and the system is fully compatible with all driving modes, including towing applications.
Advanced CANbus Integration
Equipped with full CANbus functionality, the JB4 accesses critical engine data directly from the ECU, enabling real-time tuning adjustments. Parameters monitored include:
- Throttle and pedal position
- Ignition timing and fuel trims
- Air/fuel ratio (AFR)
- Engine knock detection
- Gear selection and load
This advanced integration allows the JB4 to deliver precise, adaptive tuning and superior performance compared to basic chip tuners that lack real-time data access.
Wireless JB4PRO Smartphone Connectivity
The included JB4PRO Bluetooth adapter allows seamless wireless connection to iOS and Android devices. Using the free JB4PRO app, you can:
- Switch between tuning maps on demand
- Monitor and log real-time engine data
- Read and clear fault codes
- Perform firmware updates with new features and performance improvements
The adapter is housed داخل the JB4 enclosure for enhanced durability and a clean, factory-like appearance.

What is a JB4?
The JB4 is a plug-and-play performance tuner for turbocharged vehicles. It connects between your vehicle’s sensors and ECU, allowing it to safely modify boost, timing, and fueling in real time. With CANbus integration, smartphone connectivity, and continuous firmware updates, the JB4 provides unmatched performance gains without permanent ECU modification.
Is the JB4 a real tune?
Yes. The JB4 dynamically adjusts engine parameters using real-time data to deliver safe, smooth, and significant power gains—comparable to ECU flash tuning, but without unlocking or flagging your ECU.
