Are there settings that will cause AT to change something other than VE? I haven't found any, but I'm not that edumacated on it.

When you send a tune to the power vision there is a box that comes up. It asks what you want to name the file and what slot to save in. Also on this box is 2 check boxes. Lock tune and disable EAUO. he must have checked lock tune. This now meens you cannot get tune from the powervision. So if it were me i would call dyno jet and say you need to tell me how to undo this. i say this because what if some one playing around checks it by accident. i understand the tunner wants to own his stuff but if a accident is made there has to be a way to undo it. i bet Dyno jet can tell you how to unlock it.

I've seen that, but didn't realize it would cause automatic adjustments. Will AT adjust AFR and timing? I've been messing with Log Tuner for timing, but would rater let AT do its thing if capable.

Anyone have any insight to these three tables in the Timing section? On the surface, it seems if a bike tends to ping when hot, then proper settings here might help address the problem by pulling timing in those conditions. There are values in air temp and head temp, but only zeros in engine temp.
If your bike does not ping during the cooler riding season, but develops ping during the summer months, try pulling more at the relevant causal temps. Use the datalogs to find the temps and maps where the ping occurs and adjust accordingly.

Air Fuel is only set to 14.6 during an auto tune run.....then when you flash the tune to the bike the air fuel ratios will go back to what they were in the starter tune....unless you manualy changed them. A/F table will change only if you go to it and change it.

AT will not adjust for timing. You have to do a data log, create a pvv file, etc and then have the log tuner make the changes for you. The AT process retards the timing by 4*, I think, making it useless for that purpose.

Try using the Quick Tune feature. It doesn't permanently change the tune. You target specific load areas. I would reduce the High Load area by a few degrees first and see how it runs. If you still have ping, do the same thing to the Med Load area. Easy enough to experiment with to gauge immediate results.
Taken from the manual: "Quick Tune allows you to alter the last tune flashed to the vehicle's ECM without requiring a computer and WinPV software."

Just for kicks I messed with this tonight. Entered -2 in the Med & High Load areas. Thought I had a good tune. This made everything a bit snappier and lessened the vibrations. I really wasn't expecting anything performance wise. I think Wurk Turk and stailjim61 have alluded to the principle that sometimes less is more. How low do I dare go?

delta...AT basic ( with narrow band sensors ) will adjust timing. yes it does retard the timing 4 deg. but you can change max spark learn to a value and it will adjust ( retard ) up to the max spark learn you enter. You are right it doesnt make sense but it will atempt to retard it if needed. The default setting is set to zero for max spark learn. setting this to zero basicly turns this function off.
Dynojet recomends not using spark learn function in AT basic, but they say you can use it with wide band sensors. This has always had me puzzled because i assumed that with AT pro it would also retard the timing during an auto tune run. But i dont know. maybe it doesnt because the A/F ratio is set in the 13 range.
