ECM Calibrator

The Harley-Davidson Screamin' Eagle Pro Street Tuner offers next-generation performance tuning with both wireless and wired options, maximizing performance while remaining 49-state emissions compliant. This tuner can be used with initial upgrades like high-flow air cleaners and performance mufflers, and subsequent Stage upgrades can be matched by uploading the proper ECM calibration. Key features include tuning via Bluetooth using the Screamin' Eagle Street Tuner mobile app, which provides free online access to the latest factory calibrations. The app offers a guided Smart Tune process, Smart Tune Live for dynamic engine data tracking, and the ability to store and download run-time data for analysis of air/fuel ratio, O2 sensor readings, engine speed, and more. Users can make detailed changes via a desktop application, with adjustability for Spark Advance, Throttle Progressivity, and Volumetric Efficiency. The mobile app also provides new performance widgets like Engine Head Temp, Battery Voltage, and Manifold Absolute Pressure. For environments with poor Bluetooth connectivity, such as dyno rooms, a Tuner Cable kit (P/N 41001142) is available separately for computer connection and fine-tuning of specific calibration parameters. The Pro Street Tuner includes the Bluetooth Communications Interface (BCI) module and grants unlimited access to the latest software updates and calibrations from Screamin' Eagle. It is compatible with the Screamin' Eagle Smart Tune Pro Automatic Tuning Module (P/N 41000445A) and does not impact the Harley-Davidson factory warranty. Note that the Screamin Eagle Pro Street Tuner may only support up to 2022 models, with later models potentially requiring the Screamin Eagle Street Tuner, which are locked to the ECU they are originally installed on.
