Default it can in the short term also

Depends on how bad it is. If you're running 21psi of boost on pump gas, the detonation is going to burn holes in your pistons very quickly.

It only took my buddy about 4 minutes of driving his 3000gt with the fuel computer set wrong before it burned off the edges of two of the pistons and the top ring on each one.

Default detonation and pre-ignition are different things...

detonation is nearly instantly damaging, pre-ignition (pinging) is only mildly destructive to the valve seats.
