The Screamin' Eagle Pro Street Performance Tuner 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 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. Plus , you have free online access to the latest factory calibrations. Ideal for real-world street performance applications , 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. 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. And unlike other race tuners or engine controllers , the Screamin' Eagle Pro Street Tuner does not impact your Harley-Davidson factory warranty coverage.
