I tried using a cheap microphone attached to the engine block while tuning the emanage ultimate. Live was too difficult, but recording on the laptop worked well. I could hear the noise change with ignition timing even before the actual rattling started. Could hear all sorts of other stuff too, like gearbox workings etc. Just thought I'd throw that out there in case someone wants to try it.
