Description
The Burger Tuning JB4 Tuner for the 2024+ Mazda CX-90, CX-60, and 2025+ CX-70 3.3L Turbo delivers up to +70whp and +60wtq on a stock vehicle—transforming your SKYACTIV® Turbo into a stronger, more responsive performer. This advanced plug-and-play tuner works seamlessly with the factory ECU, remapping boost, timing, and fueling for optimal performance while keeping fuel economy unchanged during normal driving.
The JB4 connects to two easily accessible engine sensors and integrates via a CANbus OBDII connection, allowing it to monitor and adjust over 40 critical engine parameters in real time—including boost, throttle position, timing advance, air/fuel ratio, fuel trims, and knock activity. Competing tuners without CANbus simply can’t match this level of data-driven tuning precision.
With 8 preloaded maps, E85 compatibility, built-in safety systems, and boost-by-gear control, the JB4 delivers consistent, reliable power for daily driving, spirited runs, or towing. Pair it with the JB4 Mobile or JB4PRO wireless adapters for complete smartphone-based logging, map switching, and firmware updates.
