if it to far retarded it shouldnt ping, it will either go like a dog or have a flat spot..
might have asked this before?

with ngk plugs the higher the number the cooler the plug.
a cooler plug can help stop pinging...

Hmm makes me think about my motor (ED VCT-BBM) being VCT head maybe the reccomended plugs for a AU2 VCT might be a go as the standard ED plugs just ping under load and have chased it for ages with a timing light advancing and retarding HMMMM.........
