Power Vision Information Thread
I've done a lot of reading, but I've yet to find the secret decoder ring that gives me the actual information I need to do this without ignorance. Can someone PLEASE point me in the right direction? I would even settle for a well written guide to using the QuickTune parameters - I have a feeling that's all I really need to work with since all I've done is add a Big Sucker and some V&H Softail Duals. It's kinda frustrating that DynoJet seems to have nothing to offer.
I've autotuned a few different times and gotten pretty poor results, lots of decel popping and there's high rpm shift pop between 1-2, 2-3 and occasionally 3-4. Increasing the percentages for decel and high ve values in QuickTune and applying them to the Autotuned map seem to yield somewhat better results, but I'm really flying blind here. Hoping someone can help me out without having to get a masters degree in ECM tuning to get there.
Thanks in advance.

Earlier during the beta testing I asked the same question. The answer I received from Dynojet was this:
- Refine your Fuel / VE requirements and while doing so, ensure the Max Spark Learn is set to 0 (which is the default)
- Once the fuel side of the equation is nailed down, focus on spark
- If using AT-Basic, then youll need to start with a tune that ADDS at least 4 degrees, if not more to the spark tables (remember, AT-Basic removes 4 degrees of spark as part of the routine, so in order to get back to you normal spark tables, you would need to temporarily add 4 degrees ..hope that makes sense).
- Disable the fuel learning by setting the Max VE Learn to 0
- Set Max Spark Learn to 10
- Proceed with AT process
- Once complete, youll need to remove the 4 degrees of timing you added to the tune you started with and adjusted with AT.
Trust me, Jamie's way is easier and more accurate. When I first attempted this the AT did not pick any knock activity up. It only showed during datalogging; and, the log tuner software corrected it.
I bought the system from FM and they provided a map based on my setup. It really didn't work well so I sent a copy of the map back, plus a log file and a description of what was happening, at what RPM ranges, etc. They sent another back and it was better, but not great.
When autotune and quicktune came out, I used the 2nd map as a starting point for autotune basic. I ran 3 different logs and applied the changes. I also used quicktune to adjust some values in real time to see if I could improve things - mostly in the VE section and that has helped some.
Here's the thing though, until your post, I didn't even know what DE stood for, I still don't know what VE stands for and I have no idea what positive or negative values for those even do or how much value I should be adding in either direction.
So I went hunting for a quicktune guide on Dynojet and FuelMotos websites and found nothing. Someone out there must have something that says: here's a list of the different tunable variables in quicktune, here's what each value effects, here's the increment by which you should try adjusting said variable. Wouldn't that make sense? I mean, if you're going to offer a product, shouldn't you at least provide documentation on how to use it?
And with all due respect, I feel this sub-forum is exactly where we should be offering tuning 101 info, I was surprised that I couldn't find something like what I described above stickied right to the top of the list along with this thread. It seems like the first thing anyone would need to get started.
Again, thanks for your help. And if you can point me in the right direction to a tuning 101 info that I can correlate to the abbreviated terms on the PowerVision
quicktune section, links, quides, product documentation, etc., it would be much appreciated.

I feel your pain, I was struggling as well when I got the PV. I just kept reading and re-reading the threads, working within the WinPV software and log tuner. After a while things started to make since, for the most part. I'm at the point in my tune that I feel the VE's are dialed in but now I need to work on the spark advance. I'm not 100% sure on how to approach this, what area of the Spark MAP to start from and how far can I go with the spark. I will just keep searching for information so I don't get myself in trouble.
As for a Tuning 101 that would take someone with experience and the understanding of how each tune item change effects other tune items and engine performance, I feel these people are in the tuning business and we should not expect them to give away their product.
For a listing of most tune items you can go to the Power Vision website and download the WinPV / Log Tuner Detail User Guide which provides an explanation of each tune item.
Sorry I cannot help more than this but I'm just a novice.....
This is usually the only way that I can learn something, considering I am hard headed, have difficulty listening and a "Hands On" person. Sometimes I have a hard time explaining things once I figure it out, so I hope my explanation was clear enough.
It only takes a couple of minutes to do a tune but the information that you gain is priceless.
