Description
The Burger Tuning JB4 Tuner for Honda 1.5L & 2.0L turbo engines delivers big power gains without the risks of ECU flashing. Expect up to 40 wheel horsepower and 50 wheel torque on a completely stock setup — with even greater gains possible on E85 blends or with bolt-on upgrades.
This true plug-and-play system installs in minutes, works with both manual and CVT transmissions, and integrates with the vehicle’s CANbus system to monitor and adjust tuning in real time. Advanced safety features include reduced boost until proper oil/water temperature is reached and automatic boost reduction if knock, overheating, or lean conditions are detected.
The JB4 is preloaded with 8 maps, including pump gas and ethanol (E85) options, and can be adjusted via the JB4 Mobile by DMAC app ($29, adapter required) or the JB4PRO free app. Installation is 100% reversible and leaves no ECU flash footprint, making it ideal for leased vehicles or those under warranty.

What is a JB4?
The JB4 is a state-of-the-art piggyback ECU tuner for turbocharged engines. It connects to factory sensors, intercepts and optimizes key signals, and adjusts boost, timing, and fueling for maximum safe performance. Unlike basic “boost chips,” the JB4 uses CANbus data to integrate seamlessly with your vehicle’s systems, enabling advanced tuning features like ethanol mapping, boost-by-gear, and real-time logging.
Burger Motorsports provides free firmware updates and mapping enhancements, ensuring your JB4 always delivers top performance. The system is 100% reversible, not VIN-locked, and can be moved between compatible vehicles.
