MILWAUKEE (July 27, 2010) - The new Screamin’ Eagle(r) Street Performance Tuner (P/N 41000008, $329.95) is designed to simplify engine calibrations as EPA-compliant performance modifications are made to EFI-equipped Harley-Davidson models. The kit includes the Vehicle Communications Interface (VCI) module that records up to 15 minutes of run-time data on up to 27 variables that can be downloaded to a PC via an optional USB cable. Using the included software, the motorcycle owner or a technician can evaluate engine operating parameters such as the air/fuel ratio, O2 sensor readings, engine speed and temperature, RPM and vehicle speed, throttle position, spark advance, and many more performance characteristics of the motorcycle. The VCI will also record and display service codes for troubleshooting and diagnostics.

With the Screamin’ Eagle ® Street Performance Tuner an authorized Harley-Davidson dealer can install the latest ECM calibrations for a motorcycle’s legal state-of-tune for a minor labor fee. Start with a high-flow air cleaner and Street Performance mufflers, and the dealer can upload the calibration that provides the best performance mix. Add a Big Bore Stage I or Stage II kit later, and the dealer simply downloads the proper ECM calibration to match the model and hardware. Because the dealer will have on-line access to the latest factory calibrations, it can load the most up-to-date parameters whenever the motorcycle is serviced.

The Screamin’ Eagle ® Street Performance Tuner may be installed on 2007-later XL and XR Sportster, Dyna(r), Softail(r) and Touring models (except Trike). .
