Super tuner Pro is a one way gig. Your "stock map" is not saved.
It is the current last loaded map that is held in the VCI ( the Orange box !)
It will "marry" the ECM first time it's connected up even if you don't load up a new calibration ( better name for a MAP)
In the US dealers can download a modified calibration to any bike , but all are EPA compliant , ie , not "Race Tuned"
Not as far as I am aware.
Now you can do this with TTS , it was originally an "option" , and more recently "compulsory" or the programme would not advance to reflash.
If you can "save' the original stock OEM calibration with Supertuner pro I have never done it OR seen it done
search ebay Australia. Harley supertuner. FIKMIK will show up as zodiac/aquarius or similar
