The Buell ViED for 2008/2009/2010 bikes using the DDFI-3 ECM are available on www.nightrider.com/parts/

Riders with Buell's now have access to the Patented ViED(tm) technology by Nightider.com. For Riders that just need to richen their closed loop fuel mixture, the ViED offers an alternative to high priced piggyback controllers. We do not recommend the use of the ViED with the Buell Race ECM.
Buell ViED's are sold as single units.
