2012 103 pinging HD solution
I just bought a new slim after spending months chasing problems with my Shovel only to find I am now doing the same thing on the new bike due to detonation.
Only had the new bike for a few months and am already regretting the decision to buy new.
I purchased the cables and software and started reading the SEPST sticky on this forum. When I picked up my bike, I asked if they did a real tune or just put in a canned map. He said they tuned it.
I pulled up the map that they used, and the canned map for my setup. The VE tables had been altered (probably smart-tuned), but the AFR and timing tables were exactly the same as the canned map.
I made two new AFR tables based on recommenedations from a couple of forum users. One was conservative and removed most of the pinging. The 2nd removed ALL of the pinging and all of the decel popping. My pipes are now black and dry instead of white as a bone (not excessively black), but ran as good as it always has. I made no mods to the timing table whatsoever. In addition, I pulled a fairly steep hill in 6th at about 60 MPH and it pulled strong with no pinging. Something I wouldn't have even thought about previously. I plan to lean out some areas on this map and tweak some more.
Below is the map I ran all day today with no pinging or popping.

I have the basic V&H stage 1 with a fuelpak. I am using the map they recommended with my components. 22.5K so far and no pinging or pre-ignition. I also use 87 almost exclusively. Have used some higher octane by accident, order of octane was different at a station I visited on a trip, and on purpose to see if there was any performance or efficiency gain. Actually some loss of efficiency and no performance change.
I have owned high compression vehicles that required higher octane. A 69 Vette with 11:1 and Porsche with 12:1. I know what pinging and pre-ignition sounds like and how to "time" it.
My 103 is stock inside and will stay that way. If in the future it needs an increase in octane to run correctly, then I will do it. In the meantime, 87 works just fine.
Also, a incorrect tune/ bad tune will open the door for ping, been there, and my week trip through Oregon and northern Calif, this August ( in warm temps 90-100 at times) was not really as nice as it could have been with my engine pinging from:
A bad tune And Bad fuel in CA, it sucked. Bike died on me in the O'Reilly auto parts parking lot as i was going for some Lucas fuel treatment in Crescent City, CA. Was at Redwood HD, though they could fix as I had my SEProRace Tuner with me, they said they would need to start from scratch and build a map and then it would be a tune at sea level and I live at 2100 ft, so time and location and $.... Waited until I got back home.
When I got back from my trip, I went to stealer, they did a Vtune on the SE pro race tuner, they said good to go.....
However, it would still ping.
I hope my PowerVision and TW222 cams allow for a non ping ride.
