I have come across bikes , just recently bought used , several times now where the Tuner dongle has been "lost" somehow.
Was especially common with used US imports a while back , no tuner dongle/no spare fob or key/ no handbooks etc etc.
Probably just lack of care along the way with those bulk imports by dealers.
Even happens thru' HD dealers. Another mate just bought an (admittedly well priced low K's very clean) Fatboy with High flow air and exhaust.
I could read the VIN and it had had a reflash with a stage 1 tune already , but no tuner to be traced thru' the selling dealer.
The thought of buying ANOTHER tuner dongle fro a bike that has had one already really really sucks !
Yes indeedy ! The whole TTS "locking" thing will be an ongoing problem for years to come.
Only experienced it once myself. Thankfully I was able to get an "unlock" flash from TTS but it was a MAJOR lengthy pain and I don't want to go thru' it again if possible.
Bike was a 2006 Springer special US lovely low mileage import. Beautiful bike , guy bought it on Holiday in Marina Del Rey at Bartel's HD. Only 5 in Oz , rare thing.
I had to borrow a TTS dongle by mail as part of the messaround. Now he's on Supertuner pro no more worries ( we hope !)
Copied info on Full featured tuners 100% correct.
I used to prefer the TTS system over the Supertuner pro hardware and software , but since 2011 have preferred Supertuner Pro
