Very impressive product. Easy set up and quickly usable. Lot of good data at you finger tips. Been showing it off to friends.

These things are so small, so Inexpensive. You go to Harley and try to get something done, it’ll be 100 dollars an hour, minimum. But here 300 bucks and you’ll have all the data prior to going to Harley and know what you’re getting into. It’s the best investment you could ever make!

Great Product, works exactly as described and will be very useful. I look forward to showing it off to my fellow riders. Installation was quick and simple on my 2006 ultra classic and I was surprised how much data can be seen now on my iPhone; very cool!

IMPORTANT: The adapters only work on fuel-injected Harley-Davidson models.

NOTE: Some of the early 2001-2003 models have been equipped with the Delphi® electronic control modules (ECMs) that will work with our adapters. You can find out if your motorcycle is compatible by checking the number of wired pins in the diagnostic port, also known as the data link connector (DLC). If only three of the pins are wired, then it's the Delphi® ECM and the adapter is compatible. If all four pins are wired, then our adapter is not compatible with this motorcycle.
