I talked to Fuelmoto yesterday and he suggested when doing an auto tune, burn a tank of gas. Also to ride it in all rpm and gears, don't get on the highway at a constant speed and rpm.
A good mixture of hills and turns while "riding it like you stole it" will produce the best results. Don't be afraid to get on the rpm's.

You already have the tool....PV
A bit of research, and it is easier than you think to use it
Here is FM's page for the tutorial: https://university.fuelmotousa.com/h...518-EFI-Tuning
I am running AT Pro because '06 Ultras didn't have 02 sensors. I installed V&H dresser duals for the 02 bungs and I was off to tuning. Have re-tuned several times with the changing of cams, and slip ons. The Ultra runs awesome using the AT feature. A shop even asked me what I did to my bike because it was running so well (and he has a dyno in his shop)
Have some fun with it!

Very interesting.... I would think that with narrowband sensors, you'd be asking the PV to make changes to cell areas, where the narrowband sensors are out of their effective range...
Like I said, I'm no expert, and certainly don't have the understanding or experience of Fuelmoto ..... obviously you should go with their recommendations.
I'm gonna have to compare some AT runs on same map, same bike... one with narrowband and one with wide band, to be able to wrap my head around that....

It defaults on VE tables, but you can select that it adjust for timing... but it does timing in a very different way than the VE tables.
For VE tables it will adjust up or down, as needed, to meet the known AFR.
When checking for timing, I believe it will only detect knock occurrences, and then suggest where to retard timing.
I have read some, much smarter than me, say the timing runs are not very helpful for various reasons. The reasons are all just on the outside of my understanding... so I won't try to discuss them.
In AT Pro, I have run a few timing tune runs, on Fuelmoto maps. I can't say if I did it correctly, but no timing changes were ever suggested... I just chalked that up to a really good base map from Fuelmoto...

Not really....
As Skratch said, basic auto tune is pretty simple. I could have ended my response after the 2nd paragraph.
Everything I wrote below "extraneous info---", was just to show how much you can do with the PowerVision, if you have the interest.
I was raised tuning carbs, and I am fascinated by the amount of control and adjustment you have with the Delphi EFI system...
I am trying hard to learn and understand this EFI tuning. I looked but couldn't find a basic class for civilian tuners. I paid to attend a class at DynoJet, for professional tuners, on tuning with the PowerVision: AT basic, AT Pro, & Dyno tuning. At that time in my learning curve, a lot was over my head. Luckily I sat next to Joe Lyons, who was tuning for an HD dealer then, and I believe now owns his own shop. He was incredibly sharp, and a very knowledgeable and experienced tuner. He answered all my stupid questions during breaks..... Thanks Joe!
I'd love to take that class or a similar class again....

With narrow band o2 sensors AT can only tune a narrow section of your VE'S (light load cruise) and the more overlap your cams have the more faked out the AT will be. It will lean it out too much. Dyno is the best for a all around tune as it can get hard to reach cells tuned

IMHO, the usefulness of auto tuning of spark tables is limited.

Does anyone know if I could buy a Power Vision unit and put a tune on it that was derived from a Power Vision dyno tune (the operator said he will give me the tune on flash drive), then put that tune on a spare ECM to carry with me during remote travels?
