What can pinging mean in this case?

Ah no, even with a computer controlling the works, it is possible to get pinging or detonation...

Detonation is caused by either gas whose octane rating is too low for the engine (and which in this case the computer can't retard the timing far enough back to compensate for) or the engine computer itself is whack and isn't doing its job (A problem I had on an '85 K-car years ago, the engine computer was pooched and so the car wouldn't start w/o a boost and deiseled like crazy for up to a minute after shutdown :ph34r:)
