no Andy, first time I've seen that link so thanks. I really need to learn more about using scatter plots to assist with tuning- although the TT has made things immensely easier, there are still some inaccuracies with target afr and a lot of big peaks / valleys with the VE tables- I find myself now looking to learn more about using CDE to smooth the tables, and how to further get VE to be very accurate with target AFRs. Although I'm at a bit of a disadvantage until I get my new 4.9 injectors installed- I'm hitting well over 80% max IDC everywhere with the 3.9's so I'm sure that is causing some issue.

Regarding Peaks and Valleys, try turning on the calculated field MAPxRPM and then plot MAPxRPM in the X, Duty Cycle in the Y and AFR in the Z.

And also create a filter to toss out when the motor is cold.

Rode yesterday and the bike felt great. Noticed fuel economy was a little low. I opened my tune from the power vision and became confused. I had 4 base line pvt's. I loaded tune from bike and saved to slot. Looked and the same as the last baseline tune that was in it. Looks like I am full open loop? Sent mac an email but in case he is busy thought I would let someone else see it.

your AFR table is solid "13.0" for the entire table- yes that will be open loop and is typically only good for tuning with AT PRO, if you ride that you will of course have lower MPG since the low load and cruise areas are richer than they need to be. closed loop AFR's with narrow band sensors will be 14.9 to 14.3 in your tune file. that will typically be the light load and cruise areas.
your spark advance tables are quite advanced, which is good for power, but your VE's seem a bit low and rather jaggy- quite lean in some areas as well like decel and mid rpm high load. this could be giving you some ping under load. but the ecm will detect and pull timing so not optimal but no worries.
email Mac he'll get you straightened out. when running auto tune be sure to exclude 30kpa for the minimum map in the auto tune settings- if you auto tune 30kpa and under it will only lean out the VEs
not sure what you mean by "four baseline pvt's" - do you mean you have 4 different saved auto tune session files - e.g. "000001.pvt" etc?

was this modified by narrow band basic auto tuning, or AT Pro auto tuning?

I will not auto tune this as it will just want to lean it out per mac. My afr is really good here on the chart. The dyno operator leaned it out already from macs base cal to not be too rich. Here is the cal with afr changed back.
