auto tune 02 sensor

[outback_imp]

ok guys, Getting nice outside. I picked up a laptop and loaded up the dynojet program software and fuel map for the 2014 w/yoshi slip on, So i can run the auto tune. I figured that map was best as its the only one thats the same year bike.
Couple Question , After running the bike for a session do you need to keep the ignition on to save the trims?
Also ive read some say not to save the trims every time you ride it for a session and some say aprox. 30 minute rides and save trims every time?
I figured since some of you guys have expierance with the auto tune you might have a few tips or helpful ideas.

Thanks Guys
