I was wondering about the stuff coming up in this thread so I asked a guy in the know by email. Here was his answer.......
<<<<< snip >>>>>>
In reference to restoring the incorrect original calibration a couple of things could have happened, they may have loaded Copy of Original thru the Tune Manager (this is not the same as Restore Original), or more likely what happened is they were using an early level of FW and used Restore Original but somewhere along the line a non-OEM calibration was stored as the backup, this was possible with some early firmware versions where if you did multiple ECM reads it would store the current binary in sequence. Other comments also point to this as they could not get some features to work with a different tuning platform, the user was previously using PV/AT Pro and the closed loop stuff would have been turned off so it completely makes sense. Regardless, the first original Power Vision .STK would have been backed up automatically if it was ever connected to WinPv and could have been retrieved under Documents/Power Vision/Original Tunes if it was indeed overwritten.
It is most important to note that currently ( actually since the later part of 2011) you cannot overwrite the original calibration from when the PV was married, it is stored in the unit and cannot be replaced or modified, this prevents any possibility of the incorrect original map from being restored which happened in the example discussed. In the case of multiple licenses, with a Dual License it stores both .STK files and automatically associates them, the only time they need to sorted manually would be in a case with a shop with several dozen licenses for a single unit, in this case WinPv would have the files automatically stored under Documents/Power Vision/Original Tunes and only the .STK for that bike can be restored.
