wideband knock sensor anyone?

[dsmcurse]

so as we all know in the modern day and age of tuning we use wideband (0-5 volt signal) O2 sensors to fine tune our fuel maps. apparently, theres super acurate to the tee knock sensors now to fine tune ignition maps. do i understand this right? is anyone familure with "Gizzmo" brand? a friend told me about a special knock sensor that comes with headphones so you can here ping & detonation. i was told of another knock sensor thats supposed to be a 0-5 volt signal wideband knock sensor with gauge. does anyone have any actual hands on experience with these "new" knock sensors? thanks in advance.

anyone use gizzmo K-MON in a dsm?

I heard of this J&S Safeguard knock/timing control computer which is similar where you can listen with a headphone , but never ran one...
