fo'shizzle, ask over here:
https://www.hdforums.com/forum/ignit...-by-admin.html
during a dyno tune, the dyno guy uses a separate wideband O2 plugged into his equipment, and tunes with that, and prolly just references the OEM 02's to double check.
I think the PV "sees" the O2 sensors in areas/bands where the stock ECM does not, and that is how it auto tunes. a common sense guess would be, it knows which way the AFR is gross out of tune (beyond the limit of the narrow band 02, and rich or lean) and it just pushes the AFR in the correct direction, till the narrow band's get a reading.
IRT to the quick tunes, they are just tabs on the PV screen, and you can learn to use them on Dynojet's YouTube Channel:
here are all their videos:

fo'shizzle: you are on the right track, the PV and the ECM want to make the map correct, and you want it to be a tad bit rich to keep the bike cool at idle,
and you can do that with the quick tune functions (also helps with decel pop if you richen up the decel range.)

Did you note what AFR in the closed loop changed to in your lambda table when you updated the stock MAP to the stock improved MAP and then again when you updated to the dyno tune?
Thanks for your help.

I checked out the video. Thanks. I'm still confused though. If I have synced up my VE tables to my AFR table, would I need to use that tab to add fuel? Couldn't I just edit the AFR table? How does that tab thing work with the AFR table? What happens if I input a percentage that increases the AFR in the closed loop beyond what the O2 sensors read. I don't understand how it works from the video.
Thanks for your help.

you can edit the AFR table on your laptop, which is not always easy (on a roadtrip?)
you can do the quick tune, with the PV on the handlebars.
so if you live at the beach, you can ride to the mountains, do an autotune to get the AFR perfect for the cooler weather, lower humidity and thinner air,
and then you could use quick tune to richen it back up to make it run cooler at idle
in other words, the AFR table is for (fine) tuning,
and the quick tune tabs are for fixing quick problems (coarse tuning?), or just globally enriching one range/RPM range.

Like already stated, most people will say after installing a tuner why didn't I do it sooner or I can't believe it made that much of a difference and to be honest I've never heard anyone say they wish they hadn't installed a tuner. Again the choices of which tuner is a wide area of topic but Safetyman pretty much laid it out like I would have as well. Powervision I think is one of if not the best on the market right now. My Dyno tuners love that they can also get a license for about half the cost and tune another bike with this system, that's what I did. Something else you may want to ask your tuner if you had a 2014 tuned already if the newer tables from the 2015 ecm's would benefit any of you by adding the update and possibly doing a updated tune, mine benefitted by gaining 10ft lbs. down low where it counts.
Just adding my 2 cents in as well but remember all bikes are lean and all bikes will run better if they have a little tweaking done. These rushmore cams have pretty good potential if properly tuned so you know what they say, Friends don't let friends ride a stock untuned HD !! Nah, they didn't really say that but it sounded good...

I am starting over. I have the PV1 now, but I ordered the PV2 cable yesterday. I had an 08 Ultra that I tuned 2 years ago. Now I have a 2015 LTD wet head I just bought. I am adding SuperTrapp Fatshots and the SE AC to it next week. I will be adding the improved stock tune to it before I do the intake, but after the Fatshots just to get things started. I was used to working with the PV, but it has been 2 years and things have changed so I will be learning to do this all over again. The 08 used stoichiometric values so I am not used to using lambda.
I see a lot of different settings in winpv that I didn't have with the 08 as well. My old brain just don't work as well as it used too.......LOL.

Has anyone else ever run into extended warranty issues with the dealer when using PV maps? I have been denied warranty service for having a non-HD map on my 2010 Ultra Limited. The dealer claimed it voided my warranty. I was very happy with the improved performance, but not too happy with my local dealer. I have a 2014 Ultra Limited now and am considering another PV tuner, but don't want to have warranty issues again.

What problem did the PV CAUSE that they wouldn't warrant?
I would highly recommend reading and understanding the Magnuson-Moss act of 1975
