The SCT BDX brings professional-grade engine tuning to any driveway. Load dyno-proven preloaded tunes developed by SCT's expert calibrators, or pull up to 20 custom tune files from any certified SCT dealer worldwide via WiFi CloudTune — no wires, no laptop required. The HD color display lets you monitor engine parameters in real time, and adjustable functions including timing, rev limiter, and wheel/tire calibration make the BDX a complete engine management device in one compact unit.

Beyond tuning, the BDX works as a full diagnostic tool — read and clear trouble codes without a dealership visit. Data logging captures session performance for playback in SCT's free LiveLink software, and DLX files can be sent via WiFi for deeper analysis. Whether you're chasing more power, better towing response, or just want to see what your engine is doing in real time, the BDX handles it all.

Windows-only software (Vista/7/8/10 — Mac not supported). SCT preloaded tunes comply with the Clean Air Act and do not modify or delete vehicle emissions. For a 50-state CARB-certified version, see part number 40490EO.
