Apparently the bike had that tune in it the day it was married. That tune was burned to the PV as "the original"
When I did my PV, I used my TTS to put the original tune back into the bike and then married the PV.

Then I put the TTS tune back in and started with that tune as my starting tune. As I recall, I never autotuned the bike with the PV autotune program. If I did, it was later. That bike did some of the early beta autotune stuff with the widebands if I remember correctly. I bet a fair amount of my original autotune logic that I did in excel, went into the final PV product. That was a long time ago.
As it turns out, right now I am beta testing autotune logic on a quite hyper motor. It gets really fun to figure out what data to keep and what is just what you are going to get. Dynos are almost out of the question as even an option.
Great fun doing 0 - 90 mph in about 6 sec.
