All current production S&S modules are closed loop compatible, and all older S&S modules can be updated with current calibration by simply downloading software from the S&S website at sscycle.com/protune Please note that maps created for older versions of the VFI software are not compatible with the new closed loop software, however they can be converted to closed loop if desired. S&S VFI systems installed on 2004–up Harley-Davidson® models incorporate a speedometer calibration feature. Due to the extreme range of control offered by the S&S VFI modules, we recommend that they be installed and tuned by S&S Certified VFI Tuning Centers. Check www.sscycle.com to find a tuning center near you. NOTES
