Went out for a test ride today with the TT- i could tell right away the bike was running better just firing it up, letting it warm up, then a couple of blips on throttle. motor sounded crisp and more responsive than usual. the map I loaded was a TT enabled tune file from DJ. I only edited the timing in the decel area of spark tables and enriched the lambda table a bit.
Enabled a TT-AT session with min map set to 30, min ve learn set to 0.01, max ve learn set to 50, min hits set to 3. took a good half hour ride through canyons, town and some freeway. Bike ran very good, very strong, overall impressed.
But here is the kicker and need some help- when I got back home looked at the AT TT and it said "0 learned" for everything. not a single ve learn or hit. Did I miss something here?
when I enabled TT AT (I selected "Target Tune Auto Tune" correctly from options) I let the PV do it's thing, followed prompt to turn off key / back on, started bike and verified that AT TT showed enabled. also verified that WB sensors were operational and reading AFRs. After got back, stopped engine running with handlebar switch, key still on, exported AT session to a tune slot. disabled TT AT. opened up the new AT TT tune file in WinPV and compared to previous tune file. zero changes indeed.
Ideas anyone on what I missed / why no changes by AT? the TT enabled tune file DJ sent me can't be that perfect out of the box. the TT-enabled tune file is attached here.

So if the ECM was married to a SE tuner, or let's say a TTS, it won't have any affect on the PV marrying up to it?
What I'm trying to avoid is buying this bike, not knowing what was used to tune it, and then finding out the tuning device used won't be compatible with PV. Then getting stuck having to buy a new ECM.
Hope this is making sense.

"Will the Power Vision overwrite a non factory tune? In most cases yes; the Power Vision doesn’t care what tune is in the ECM. When the Power Vision is married to a bike, it saves a copy of whatever tune is in the ECM at that time. This tune will be saved in a hidden slot and called Original tune. If you restore Original tune with the Power Vision, it will write this tune back to the ECM"
So, you should be able to reflash the EMC with the Power Vision and new tune. The only time I can see needing the stock tune is if you are importing a tune from the Power Commander 3/5. That requires the stock tune to complete.

Olie- the only way to upload it here is to add ".txt" to the end of the file name. rename the file and remove the ".txt" so it then just has .pvt as the file extension

If bike was tuned with an SE tuner then no issue at all.

I'm also wondering why a 2013 tune is using TPS for the VE tables and not MAP?

Windows 10- joy. 
That is the pre-AutoTT file you have. The post AutoTT file was identical down to the byte size of the file. AutoTT did not change a thing on it.
I plan on doing some data logging tomorrow- Ive been tuning with the PV manually for about a year and come up with some decent tunes based on data logging.
I'm sure something is not quite right with the TT's operation- either that or I'm missing some step in regards to using TT not present in manual / literature. Are you using TT on your PV?

I don't normally look at that screen- when I AT, after a tuning run I look at the line summary which says % of changes etc - then I will look at green screen, which was blank due to the "0% changed" issue.
I took a ride today with it in normal mode, AT disabled, and the bike ran really flat. not good at all. actually felt pretty lean if I had to guess.
I wonder why it ran so well in AT TT mode (really well in fact) but normal mode something is definitely not right. the throttle crispness is gone, power is reduced. exhaust smells lean even though my lambda map is on the rich side.

As far as auto tune, we will need to know if it was populating data from the auto tune screen and if there were any errors present during this process. If the data shows 0%, chances are something is not correct in your Auto Tune settings or something was not updated along the way

thanks Jamie- I plan on doing this bit of checking and data gathering tomorrow, I will definitely set up and log those signals. I had updated everything prior to loading the new TT map onto the PV. I did initially check to ensure the WB O2 sensors were showing data in a PV gauge screen. that checked out ok.
when I first got the TT map from DJ, i was all up to date with WinPV which is when I opened and edited the tune file. My PV firmware was up to date. I needed one incremental update to the tune DB and did that before loading the TT tune onto the PV.
With the tune files attached (the one I used today), are you able to see if the TT got stripped out? the numeric file is the one DJ sent me and the renamed one is the same file but with a few edits in WinPV. i added .txt to the file name so it will upload here. Thanks of course for your help.
