Harley Screamin’ Eagle Performance Tuner

Harley-Davidson tuner updated for 2012; no more dealers needed

Harley-Davidson owners can now use the Screamin’ Eagle Street Performance Tuner (P/N 41000008B, $249.95) to upload and install the latest factory ECM (electronic control module) calibrations to match specific hardware upgrades, including high-flow air cleaners, Street Performance mufflers, and Big Bore engine kits.

Previously, an authorized Harley-Davidson dealer was required to complete these software uploads. The revised Street Performance Tuner also gives the owner the ability to view and clear ECM trouble codes, and to collect real-time vehicle data, which can then be displayed on a computer screen. Finally, Harley-Davidson has lowered the suggested retail price of the Street Performance Tuner to $249.95.

With the Street Performance Tuner, the Harley-Davidson owner can install factory-calibrated ECM software that will deliver the best all-around performance for a specific model and its state of tune after EPA-compliant performance modifications are made to EFI-equipped Harley-Davidson models.

The kit also 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. 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.

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