Am I the only person that is having bad luck with the Power Vision?
I have a completely stock 2012 Sporster 1200 Custom.
Every time I run a AT on the stock base map it gets worse, almost all the cells are heading in the lean direction by 5-10%.
These bikes are already very lean from the factory, this ain't good.
I've run Dynojets 'Improved Stock Tune' but it is a open loop Power Commander tune, Pig Fat Rich and a lot of stuff is turned off and not used due to the older technology. I really wanted to just improve my stock tune and keep the closed loop for all its advantages.
I guess I really need to just find a proven tune to load in and see how it runs.
Don't know what to do next, any suggestions?

I'm a little unsure of why you would buy a PV for an otherwise stock bike. What are your goals or plans that brought you to purchasing the PV in the first place? (Usually folks start with new pipes/slip-ons and an AC to allow the bike to breath better.)
Have you tried running the AT against DJs "improved stock tune"? Did you buy this from FuelMoto or another vendor?
I haven't noticed a lot of Sportster 1200 folks out here. Have you tried asking in "Sportster part of HDforums too?" ..just in case one of them has been there and solved your same problem.
Hopefully some folks will come along to give you some advice.

I'm a pretty much a noob, with enough info to be dangerous, but this is the explanation I received from both DJ and FM. so YMMV

I did not get the Power Vision from Fuel Moto, it was a gift, so no maps from them.
Dynojet only has 1 map for my bike, 'Stock Improved Tune' its an imported Power Commander tune that is open loop. A lot of stuff is turned off so this tune could work with the PV. DynoJet recommended that I really not use it and just AT my stock tune.
I was hoping to eliminate the surging, heat and lean factory settings by using the PV to tune them out but it appears to be heading in the wrong direction, leaner in a lot of areas.
So I'm stuck with only 2 Tunes, DJ and my stock one that I can AT and neither seems to be a good route to take.
My bike does not run 'bad' with either route I take, just expected more of an improvement. I was expecting to see VE's head toward the richer side by 5-10% and the temps go down some and eliminate surging at cruse.
I know how to use it properly. Been twisting wrenches for over 50 years and my career is in electronics 40+ years. No problem in understanding and using the unit at all.
Just really don't understand the results I'm getting.

Sounds to me like you got all the same problems (or more with the surging) as the Twincam engines. Might be time to break out a few pesos and eliminate the cat, put on a decent air cleaner and some less restrictive mufflers. [I just went to the DJ sight and notice that all of the tunes they have for Sportsters, even with mods are all PC imports. There's an opportunity for some DynoTuner like FM I would think.]
I wonder if how Sportster owners are dealing with this? Or are they all just looking for loud pipes and hot womin'?
