This has probably been asked a million times but here it goes. I am new to this whole tuning thing and its time to start testing. I understand the concept of detonation and what causes it, but I really don't know what I am listening for. I've been told its a pinging noise and you just learn to hear it. I don't understand how you can hear it over the engine/exhaust noise since it is so loud normally. Could somebody give me their best explanation of the sound I should be listening for or direct me to a source that explains it? Thanks in advance!!
