[Diy_efi] Crank sensor for knock detection?

[PuffnSmoke]

Ok, too much sour mash, the question was supposed to be was it possible
to use the crank sensor to detect detonation in an engine...

Yeah knock sensor for knock detection is easy, lol.  What about
analyzing the crank sensor waveform in real time to detect detonation.
Is it possible, and is it done on production engines that don't come
with knock sensors?

Thanks

Mike
