Description

The Burger Motorsports JB4 Tuner is an engine management device engineered for Mazda's SKYACTIV 2.5L Turbo engines, offering enhanced performance through factory ECU integration. This plug-and-play unit connects to two easily accessible sensors within the engine bay, allowing it to remap boost, timing, and fuel parameters without requiring a full ECU reflash. The JB4 tuner is compatible with a range of Mazda models, including the Mazda 3, Mazda 6, CX-5, CX-9, CX-30, and CX-50, with specific fitment varying by model year and generation. It comes with a 5-year warranty.
