Only one thing really motivates me to public embarrassment Mike. I only think I can use this as a microphone for headphones, not 'puterized processed so a 'puter brain can work with it. It might be rigged to trigger Powerarch curve change but boost PSI switch ahead of detonation onset zone makes more sense to me. Lugging is just a fact of Ozark off highway commutes and worse on po folks driveways. Not in high gear stupid jerking chugging lugging, but still dang high-ish throttle w/0 any rpm increase. The obvious place is center of head and Peels hole is vacant a long time. Then there's pushing Peel's luck with my twitchy Lake injector hand. Lots to learn on these buggers, but for our clunkers will need a broadband into the 2nd order freq, ie: over 12grand otherwise as engine reaches say 6700 rpm the sensor goes off to shut auto pilots down or cover up real detonation events. The other interesting thing with headphones is said to hear all sorts of sounds that later may help alert or diagnose or monitor wear or change in tune. Hm wonder if youtube has audio examples?
