Lightbulb Re: Nozzle spray angle...

I have been talking with one of our top tuning shops about this, and they
say that at the noise levels I am getting there is basically no way any kind
of detector will be able to separate real detonation from mechanical noise.

However, the human ear is very good at picking up the sound of real knock
even with high levels of background noise. So I will spend a bit of time with
headphones plugged into the jack provided on the ECU for listening to the
knock signal. If I can't provoke any knock by loading the engine at different
speeds, I'll leave optimising the ignition timing until the car goes on the dyno.

It makes sense that you either have to have a knock detection system that
you can rely on to only report genuine knock, or have no knock detection
at all and a good tune
