Ping Ping Ping
Can't get this pos to stop pinging! I went to colder plugs, (which is an old racing trick) and that helped alot. But, unless I add octane boost, it pings on acceleration. It's a 15 with a stock 103. Put in a FuelPak3. NO difference.
Just looking for.... what worked for you.

mr. ed makes an excellent point!
if the engine is loaded up (sometimes does not require much) it will detonate and is diff from a ping.
while heat range is considered a "trick" it is only so under trying circumstances. if you are causing a stock plug to run so hot that it pre-ignites fuel, it is the last of your worries.
there are fuel quality issue more than octane and since it is just about time for winter blends to go summer, it just maybe fuel. then there is lead time and if you still run the voes, it can contribute to the issue, i do not use it for that very reason on clutch off, i run rpm base ign adv. then there is mix issues, too lean, too rich (usually not so) as the ratio effects flame front and temp. so you might need to roll out some ign lead and look at short term fuel trim numbers. now if you have mods, another piece of the puzzle.

No. Even if I down shift to pass. Obviously it's worse in hotter weather, but still a little in the cool. I don't usually run it hard, but when you need to get out of the way or get into a spot, it just detonates. Done this since day 1. The dealer here doesn't have very good techs. Only book people.

Ignition timing, fuel mixture , engine temp would be the three main points of concern. Have you confirmed static ignition timing is correct and you don't have too much total advance? What do the plugs look like after running for while? Does the bike stumble on acceleration like its too lean? If the bike has a knock sensors, maybe they're not calling to kick back the timing when they should. The less likely culprits would be compression ratio and hot spots in the chamber. Being a stock bike, not likely.

Does the FP3 let you adjust ignition timing? I know the Power Commander does. Ill bet that would help if you could retard the timing a little. I had a stock 103 that was bad to ping. For some reason it did better with HD brand plugs.

FP3 still doesn't have logging and doesn't even show knock as one of the displayed signals so you are not going to get much help I'm afraid.
Best you can do is display RPM and MAP on your mobile and try to guess where the knock is, then manually play with the spark tables. Not exactly scientific but there you go.
You could try to manually edit the spark tables back to stock values ...V&H and Dynojet seem to bump up the top right of the table by 3 or 5 degrees. Mine had knock in that area so I took it back to stock and it was much much better (although I had a cam and a touch more compression so ymmv)

There has to be more detail to the story than the initial post.
