340 Pinging using 94

I can take a video.

For the "Vehicles don't ping decelerating", why is that? The engine is still firing while decelerating, it's just doing so at a lower RPM. And if the detonation is now occurring at a lower RPM after retarding the timing, I don't see how it's out of the question.

Now I could very well be wrong, and I am not using experience to justify my thoughts, just logic.

Yes, the engine is firing, but the load on the engine is not there like it is while accelerating. With the throttle blades closed, there is very little fuel being fed into the cylinders.
