Harley-Davidson Street Tuner

The Screamin’ Eagle® Pro Street Performance Tuner (H-D Part# 41000008c) is designed to simplify management of engine operating parameters as performance modifications are made. Once installed, the kit 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 Stage 1 kit that includes a high-flow air cleaner and Street Performance mufflers. Then upload the calibration that provides the best performance mix. Add additional Stage Upgrades later, and simply upload the proper ECM calibration to match with your model and hardware. Plus, you have free online access to the latest factory calibrations.

Ideal for real-world street performance applications on both new and used Harley-Davidson motorcycles, the Pro Street Tuner provides the adjustability to account for bike-to-bike variation and for changes to cams, heads, intake and exhaust while maintaining closed-loop fuel control for fuel economy in the part-throttle operating range. For use with '17-later XG, '14-later XL and '07-later EFI Dyna®, Softail® and Touring models.

Unlike other aftermarket tuners, The Screamin' Eagle® Pro Street Tuner actually talks directly to your motorcycle’s ECM and re-programs the motorcycle’s operating system. It isn’t a piggyback system that tries to fool the ECM into adding more fuel or changing the ignition timing. The Pro Street Tuner plugs into the bike’s data port, so no splicing or under-seat hardware is required. The Pro Street Tuner does not remain attached to the motorcycle during use. It simply acts like a data port key for the programing. Unlike other race tuners or engine controllers, the Screamin’ Eagle® Pro Street Tuner does not impact your Harley-Davidson® factory warranty coverage.
