Tunerpro refresher help!!

[newyorkbuell]

Hey everyone to start out its been awhile, my bike is a 06xb12r with a factory race kit. Now it has been a year or more since i talked to mike about tuning with tunerpro. No so much time has passed i forgot how to use the program. I can connect and burn maps, show live data, log and what not. Well i took the bike out any did a datalogg session and repeated a few times and it tunerpro seems to want to keep removing fuel all over the map while my AFV keeps rising. So there has to be something im doing incorrectly. Can someone give me a decent rundown of things that need to be done to tune correctly with just the narrow band o2. Some things i can remember but do not know if they are correct to do.

Do i lock the afv at 100? Do i turn the o2 sensor off while logging? there has to be something im doing wrong for the program to keep removing fuel.

Yes, you have to set the AFV to 100 and turn off the correction/lock it. If you leave the O2 correction on, you'll end up chasing it around. If you disable it, you should have a clean point to work from. You can go through the cycles of logging and adjustment. Once you're happy, you can turn the correction back on and set the AFV to 100 again. In theory the AFV should remain very stable around 100 (as long as atmospheric conditions remain constant).

I'm going from memory as well, so if there is a flaw in this logic, someone chime in please.

I have been told you can log and make changes both ways, with leaving afv locked at 100 or leaving it open to changes. Every tuning guide i have read seems to have great info on how to datalogg and tune but always leave some things out and that leaves me guessing what to do..
