41000008C 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.•Features a guided Smart Tune process to enable quick navigation through the software and permits tunability to optimize performance and drivability without compromising fuel efficiency , emission levels , engine durability , or 50-State U.S. EPA compliance • Stores up to 15 minutes of run-time data that can be downloaded to PC , allowing you to view and evaluate the bike's air/fuel ratio , O2 sensor readings , engine speed and temperature , RPM and vehicle speed , throttle position , spark advance and much more • Vehicle Communications Interface (VCI) will record and display service codes for troubleshooting and diagnostics • Smart Tune Live , a dynamic method to track engine data by running vehicle through a range of RPM and throttle positions , reduces time to modify existing Volumetric Efficiency tables (works on models with factory-installed O2 sensors only) • Adjustability to Spark Advance , Throttle progressivity , and Volumetric Efficiency to custom tune the performance combination • Includes the Vehicle Communications Interface (VCI) module and unlimited access to the latest software updates and calibrations available from Screamin' Eagle , Tuner Cable kit sold separately • 41000008C fits select California models up to and including 2020 models. 41000008C does not fit California '21-later models.
