Go to tuneecu.com and download tuneecu. order a cable for it. ($10-20) the site has all the info. Plug the PC into the bike via the cable and you can read the map in the ECU and it will tell you what map it is. The tuneecu site hosts all the triumph tunes for the tbird and each one tells you what it's for. the one you want for the storm 1700 with tors is the 20310 tune. It's worth getting the cable because besides being able to load maps with tuneecu, you can check them, alter them, adjust a number of things including speedo accuracy, throttle balance, check the error code when the bike's engine malfunction light goes on, etc etc.
As usual you're a veritable font of all knowledge in Triumph matters!
