Gain up to 80whp / 100wtq on 3.0L and 50whp / 60wtq on 2.0L Turbo Acura Engines The JB4 Acura tuner is a powerful plug & play performance tuning system designed for modern turbocharged Acura engines including the Integra Type S, TLX Type S, TLX 2.0T, MDX Type S, and RDX 2.0T. The JB4 connects to two easy-to-access sensors in the engine bay and works with your factory ECU to safely remap boost, timing, and fueling for significant horsepower gains and reduced turbo lag.
No ECU flash required and fully compatible with locked ECUs. Installation is extremely discrete and unlike traditional ECU flash tuning the JB4 can be removed quickly without leaving a trace.
Your vehicle’s factory ECU never detects the additional boost or power levels. Fuel economy during normal driving remains unchanged and the JB4 is compatible with all factory driving modes.
The JB4 includes a plug & play OBDII CANbus connection allowing it to read critical engine data directly from the ECU in real time including pedal position, throttle position, ignition timing, fuel trims, air/fuel ratio, engine knock, and more. Other tuners without CANbus integration cannot monitor or adjust tuning based on this critical engine data.
Using this advanced data input the JB4 Acura performance tuner delivers huge power gains with smooth and reliable power delivery. The JB4 also includes multiple performance maps, smoother partial throttle tuning, additional engine safety systems such as lean protection and overboost protection, advanced logging capability, boost by gear control for improved traction, the ability to read and delete fault codes, and ongoing improvements through free firmware updates.
Wirelessly Connect to your JB4 Add the optional JB4 PRO Bluetooth adapter to connect the JB4 tuner to your iOS or Android smartphone. The JB4PRO mobile app allows you to monitor engine data, change performance maps, record data logs, and update firmware as new features and more powerful maps are released.
The JB4PRO app provides a clean user interface with built-in help menus and advanced data logging tools that can estimate performance and help identify tuning issues.
