The sound is really only noticeable with the windows down and no radio on which is why I think it is only a "slight" ping. Is it possible that Nissan finds a small amount of ping acceptable? Unfortunately I'm not very experienced when it comes to newer engines. My last car was a carburated 87' Nissan Sentra.

I'm really surprised the ECU lets any detonation occur - at least that's audible. I figured it would just back off the timing.
