Description
Unlock the full performance potential of your modern Acura turbocharged engine with the JB4 Performance Tuner, a cutting-edge plug-and-play solution engineered for maximum power, precision, and reliability. Delivering up to 80 wheel horsepower and 100 lb-ft of torque on 3.0L engines, and up to 50 WHP and 60 WTQ on 2.0L engines, the JB4 significantly enhances acceleration, throttle response, and overall driving performance—without requiring an ECU flash.
Plug-and-Play Installation – No ECU Flash Required
The JB4 installs quickly by connecting to two easily accessible sensors in the engine bay and integrates seamlessly with your factory ECU. It safely remaps boost pressure, ignition timing, and fueling, reducing turbo lag while delivering smooth and consistent power gains.
Unlike traditional ECU tuning, the JB4 is fully removable without leaving a trace, and your vehicle’s ECU remains unaware of increased boost levels. It is fully compatible with locked ECUs, all factory driving modes, and maintains factory fuel economy during normal driving.
Advanced CANbus Integration for Real-Time Tuning
The JB4 includes a plug-and-play OBDII CANbus connection, enabling it to read and process critical engine data directly from the ECU in real time, including:
- Throttle and pedal position
- Ignition timing and fuel trims
- Air/fuel ratio (AFR)
- Engine knock detection
- Load and boost parameters
This advanced data integration allows the JB4 to deliver adaptive tuning strategies, enhanced safety systems, and superior performance compared to basic tuning devices.
Wireless JB4PRO Smartphone Connectivity
The JB4 includes the JB4PRO Bluetooth adapter, allowing seamless wireless control via iOS and Android devices. Using the free JB4PRO app, you can:
- Switch between performance maps on demand
- Monitor and log real-time engine data
- Analyze performance metrics and diagnostics
- Update firmware with new maps and features
The adapter is fully integrated داخل the JB4 enclosure for durability and a clean, OEM-style appearance.

What is a JB4?
The JB4 is a plug-and-play performance tuner designed for turbocharged vehicles. It installs between your vehicle’s sensors and ECU, allowing it to safely adjust boost, ignition timing, and fueling in real time. With advanced CANbus integration, smartphone connectivity, and ongoing firmware updates, the JB4 delivers significant performance gains without permanent ECU modification.
Is the JB4 a real tune?
Yes. The JB4 actively monitors and adjusts engine parameters using real-time data, delivering safe, smooth, and substantial horsepower and torque gains comparable to ECU flash tuning—without unlocking or flagging your ECU.
