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 the state-of-tune of your bike. 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 is not 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.
After you upload the proper ECM calibration, dial it in with the Smart Tune function. New for 2017, the guided Smart Tune process enables you to find the right calibration for your build, set the tuner to a data collection mode and then allows you to incorporate the data after the ride with just a few clicks. The ECM calibration is then custom fit for your bike. The module will store up to 15 minutes of run-time data information that can be downloaded to your PC, allowing the rider or technician 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 many more performance characteristics. The Vehicle Communications Interface (VCI) will also record and display service codes for troubleshooting and diagnostics. The kit includes the Vehicle Communications Interface (VCI) module and unlimited access to the latest software updates and calibrations available from Screamin’ Eagle®.
