The FP3 does come in two versions, one for HDLAN and one for the older SAE J1850 connector that covers 2007 through 2013 Touring models. As long as the customer orders the right connection type for his particular bike it will work. The fact that it will fit the bike connection wise still doesn't mean they have maps for your combination however. As is the case with most companies in this business, the priorities are to develop maps for the newest models first. Considering how many possible equipment combinations are available, developing decent base maps for everything is a big task. I'd guess if they don't have a map for an older model now, the odds of them getting around to making one are slim to none.
