 I am a newbie basically when it comes to tuning.  I have had a power commander III, V, and now a power vision.  I purchased the power vision for a variety of reasons (the two big ones being that I can purchase a number of licenses for a number of bikes and two because I wanted to use the auto tune function to get the most out of my bikes).  After using the auto tune function I don't seem to see any improvement from the canned tune sent by dynojet, in fact it is worse after I flash the ecm with the learned map.  Where can I learn about all those variables that are in the table, and what they should be?  It is all Japanese to me at this point.  Like I said I had hoped the power vision would take care of all the guess work for me with the auto tune function.  Is there some reading out there somewhere that can instruct me on what I should be doing manually to change values?  Thanks in advance.

Have you watched dynojets power vision videos on YouTube?

If you refereeing to AT basic suggest that you do dyno tune, trying to tune your bike using stock O2 sensors it won't improve the performance, also AFR set as 14.6

I use the stock 02 sensors every day to tune....and the AFR isn't at 14.6....and the performance does improve......

I, too, would like to find a good walk-through on operational theory and an in-depth how-to.
I've been using the PV with the pro wideband stuff and I am VERY impressed with how effectively it has tuned itself despite substantial changes that I have made (in stages) to the hardware. I'm still "winging it", but it's working very well, indeed, seemingly despite my own lack of finesse.
It has a great deal more power, zero drivability issues, no pinging and the heat issue is gone.
The promise is that you can do this and "get there", but, without putting it on a dyno at some point....will you know whether you got it all?

As I know while doing AT basic session PV will automatically sets the AFR on 14.6.

I have tried both methods AT Basic and AT Pro (street tune), after comparing the VE there was big deferment on collected cells, and with the O2 I was not able to see my real AFR.

With AT Pro the performance was more improved and I was able to read my real AFR, however, at the end still I need put the bike on dyno to see where I have end up, unfortunately no dyno machine in my country

Sorry for my English

Oh you're playing with a different ball than me,,,,,carry on. The TTS tuner allows you to do much more with tuning than what you are working with.

the at sets the af at 14.6 only while doing your tuning runs.  once you get the ve set, then you can set your af to what you would like.  of course, if you set it outside the capabilities of the narrow band o2 sensors, then you're going to be running open loop, not closed.

Right TTS is batter on certain  points and that's why my CVO tuned with TTS, the idea of having PV is the advantage of baying extra tune license, which goes to wife bike and my second bike.

You are right and I'm aware of that, My opinion on PV that if you are not using the pro kit AT110, you will not gain the full advantage of auto tune feature with PV

I have watched all those videos but they are pretty basic.  By the way, just to let all of you know exactly what I have been doing:  I have been putting my PV in my sissy bar bag while doing auto tune runs of 30 minutes or so, then shutting of the bike, and then reflashing with the "learned" tune.  Is there any step I am missing here?  I have been trying to follow the guide from Dynojet.

I took my bike to Doug Lofgren. Problem solved lol

Keep working on the VE until the changes Percentage is 2% or lower on learned Values, than work on the sparks with PV log, ensure to disable VE while working on the sparks
