2006 Sportster (Carbureted)
Tried a non-EFI (Electronic Fuel Injected) sporty to see what would happen. All seems functional except no Neutral Light indicator and no Engine Temp data came through.
No issues otherwise on test ride.
** NOTE: Even though the device mostly worked here that a carb'd setup is not supported. On a 2002 Harley FXDX, for example, none of the standard signals came through.
