detonation occurs more in the hot summer months... drive ur car up a hill at WOT in the summer and scan... then do the same in the winter.

No...you get more dense air when cold, hence more boost. More boost = more knock prone. When it is hotter, you do have to worry about intake temps and motor temps...not so much boost wise because the air isn't very dense so you won't make as much boost. Detonation occurs when your knocking...not because it is necessarily hotter outside.
