In your method you say to look for signs of detonation. I assume you mean simply looking for knock retard events - this is how I have been able to remove most of my ping but there is still some left. Is there other ways to detect detonation by just analyzing the data? My sepst samples the data only about twice per second so figuring out the exact affected cells is not exact science.
Also, you can purchase My Tune. You load to timing maps, recordings and few other items and it generates timing adjustments. You then manually make the changes to the F/R timing maps.
I also use My Tune to look at the hits in the different cells during Smart tuning. This helps me know where I missed or didn't get anough data. One option I like about the TTS which has this ability built in.

You might need to look at a few frames prior to the knock event.

My question is really to jluvs2ride if he has figured out any other way to find detonation than the knock events, as I still get slight ping with light load sometimes but no knock events

Here's my way as the gas where I live is pretty good:
Once you are happy with the VEs, set the AFR table to 13.5 on the light load areas and 13 everywhere else - 12.8 on the 90-100 column. That way it is not too lean. Then make sure there is no knock by looking into the knock retard events in the log and add timing where they happen

I do not believe into looking few frames prior. Logging rate is just 1/500ms and for example at 3000 rpm each frame contains data for 25 revs. The knock events I see still are with rapid change in map/tps.

I run a custom Open Loop AFR map that is a bit on the rich side. I buy premium no ethanol gas. My timing map is prety high and the bike runs great. I don't hear or see any knock.
If you are hearing ping, but not seeing a knock event you would have to watch your tach (if you have one) and your TP really close and try to figure out where it is occuring.
I think I get what you are saying about the logging rate. So at 3k rpm a single frame has data for 25 rotatations of the crank shaft. Double that, so at 6k rpm a frame has data for 50 rotations. My question is how long does a knock event last. It isn't actually a single event but rather a series of detonations. I believe you would see them.

Can you help with that?
on the other hand , if I fail to do this, Does anybody have a good map that will work on my engine? I have a softail convertible 110 with screaming eagle AC & only the mufflers were changed from stock to V&H TwinSlash 3" (& they are becoming blue)

So you are saying that you are hearing or seeing knock events? Are you hearing pinging and not seeing a correlating knock event?
I run a custom Open Loop AFR map that is a bit on the rich side. I buy premium no ethanol gas. My timing map is prety high and the bike runs great. I don't hear or see any knock.

If the condition stays the knock event gets extended and this is easy to see in the graph as the retard keeps a level over few frames. Then it is easy to spot the map/rpm/tps range and richen it and pull timing. I have concluded that it is best to look at the tps/map/rpm in the exact frame where the knock triggered and go from there.
I still see some occasional knock events, typically around switching gears and quick throttle blips but for given rpm/tps/map combo, the probability is low.
However my problem is that I still hear slight but constant knock / valvetrain noise on certain light load areas but no retard events. I was curious if you have figured out a way other than retard events to find detonation either from logs or riding.

It's all new to me, that's why I don't know what values would make me happy? The other thing is that nowadays the weather is TOO hot here in this region. What I can do is to take the bike at late night when the weather is cool & try to smart tune. I am about to ship the bike to Europe for a tour there & need to make it optimum for the long trip. Am attaching the comparison between the basemap & the tuned map for your evaluation.
Can you help with that?

And in Europe, do use the 98E gas (5% ethanol)
