I have now updated my base map several times using Smarttune. The bike seems to be running very well as far as I can tell. Not sure how to know when I've done enough recorded runs and am ready to do AFR changes....what is your recommendation harleytuner?

Looks like you made some serious progress. I'd say you are pretty much there. Remember, if you leave your cruising ranges in closed loop the bike will continue to make corrections for you. It looks like you could probably set the A/F if you'd like. Remember, at anytime you can go back to smarttune if you think you're bike needs it. Here's an AFR table that you can start with if you want.
harleytuner, thanks. Once I change the AFR values to match the table you sent, should I continue to run the bike with smarttune checked and let it continue to make suggestions for the VE tables or should I just leave it unchecked and ride it to see how it does?
The way I understand it, the VE tables should pretty much be okay now, and the AFR table will reference the VE tables to see how much fuel to add. If this is incorrect, please let me know. I think I am learning....

You got it bro. Leave the box un-checked and ride. You are definately getting it figured out. Pretty cool huh?
It is very cool. It's been both fun and educational. Yet another reason I didn't want something I could just plug in and ride. I like to tinker around with things and learn all I can. I really appreciate all the help with it. I'm going to do some riding around tomorrow and see how it's running.

Man that's great. You'll take alot of pride in knowing that you did it yourself. But it's not for everyone. Some just want the plug and play or the professional tune and thats way cool too!! (without them i'd be out of work). Have a good ride and report back.
Wish I had seen your post the other day instead of today...........You might want to consider--or return and purchase a Thundermax from Zippers (available from many places) This thing is the best out there.....automatically tunes itself. Their online tutorial makes it simple to do--trust me I'm not a genius but it really is easy. I've a few friends who junked their SE setups and PC boxes and never looked back. Educate yourself and go online to see it. You won't be sorry.
This isn't a Thundermax thread, now is it? I dropped $869 for one and in less than 6 weeks junked it and went back to my SEPST. Why? It didn't make any more power, I fought timing constantly, and it doesn't auto-tune itself. It learns just like the Smarttune feature of the SEPST, and you have to go in and continue running "automap" to tweak the map. The only positive for the Thundermax was it revved a bit quicker, but this is because there is no MAP signal to consider, just TP and RPM and "assumed" load- that's why the timing is hit and miss. It backfired a few times at the gas station as well and never auto-tuned this issue away. Zippers has good support, but it wasn't worth the extra money over my SEPST I bought new for $230.
Once a tuner is matched for the target AFR, it's a done deal, no matter what tuner is used. The thundermax doesn't have knock retard and can't protect the motor either. Oh, and by the way, I had to put the bike on the dyno with the Thundermax to try dialing it in also.
Another quick question...I rode the bike a bit today and I am happy with the way it is running. Much better than with the PCIII. I ride to work once in awhile which is about 64 miles each way. Would it be worthwhile to ride and record some normal riding on the way to work? If I understand correctly, if I load the map with smarttune not checked, it can still record data but it doesn't monitor as much? I may be wrong. It only monitors the range that's running in closed loop which would be the cells which contain 14.6 AFR?

It can never hurt to record data. It will record the data it just won't give you any A/F corrections

I rode home and data logged without enabling smartune. The recorded data will generate new AFR values, or at least that's what I am seeing. I was also monitoring knock retard as well along with map. I had made some VE table changes in order to check timing at 2500, and the recorded data generated the previous VE table values, so undoubtedly it is seeing/doing something.
Of course I accepted the VE values back in, and then adjusted timing according to the frame by frame analysis.
