Screamin' Eagle Pro Street Tuner

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.

• 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
