just wanting to know the tts i have now on my 883 iron if i ugrade to 1200 kit will the tts cover the upgrade?
Yes it will All you are changing on the bike is the barrels and pistons , hence the bigger displacement. The TTS dongle you already have "married" to the bike will be able to re-flash your original ECM with no dramas Most probably calibration FM171-002
Then again, WTF do I know ?? , I'm new here....
