Screamin' Eagle Pro Street Tuner

Next generation performance tuning made even easier. Now with a wireless and wired option, the new Screamin’ Eagle^® Pro Street Tuner is the only tuner available to maximize performance while being emissions and warranty compliant. The Screamin’ Eagle^® Pro Street Tuner is designed to simplify management of engine operating parameters as performance modifications are made. Once installed, the tuner allows you to adjust key parameters or simply upload the latest Engine Control Module (ECM) calibrations to match your bike’s state-of-tune. Start with a high-flow air cleaner and Street Performance mufflers and upload the calibration that provides the best performance mix. Add additional Stage upgrades later, and you simply upload the proper ECM calibration to match the model and hardware. With the all-new Screamin’ Eagle Street Tuner mobile app, you’ll have free online access to the latest factory calibrations via your smartphone. Ideal for real-world street performance applications, the Pro Street Tuner provides the adjustability to account for bike-to-bike variation and when upgrading through various Stage kits, all while maintaining closed-loop fuel control for fuel economy in the part-throttle operating range. Unlike other aftermarket tuners, The Screamin' Eagle^® Pro Street Tuner talks directly to your motorcycle’s ECM and re-programs the motorcycle’s operating system. It is not a piggyback system that tries to blindly fool the ECM into adding more fuel or changing the ignition timing. The Pro Street Tuner discretely plugs into the bike’s data port, so no splicing or under-seat hardware is required. And unlike other race tuners or engine controllers, the Screamin’ Eagle^® Pro Street Tuner does not impact your Harley-Davidson^® factory warranty coverage. 49-State U.S. EPA compliant.
