"super sonic ear" used to monitor detonation?
I remember reading a tread on here a long while back, about modifying one of those "super ear" things that radioshack carries to listen to detonation. Anyone know what i'm talking about? supposedly it worked pretty damn well.

Or you can do what we do and use a medical stethscope, take the end of it off and use a vaccum line to an extended stud somewhere on the block. If you use an extended stud on the intake manifold you can do it that way. You can hear everything..

I always thought it would be cool to run the electric output of a knock sensor into an adder circuit with your stereo as the other input so you could hear knock pumped through the sound system on top of the music.

Re: "super sonic ear" used to monitor detonation? (RioNinja)
hey, good idea 
I still like the "super ear" idea, since i plan on running it into the AUX on my stereo instead of using headphones. Much better than any radio station
The article was really simple, i think all they did to the piece was adjust a potentiometer(sp?) inside to tone down the sensitivity a bit... i THINK. someone has to have a link to it...

interesting....
does anyone know where we could find out what detonation sounds like ? i dont mean the actual noise, but more what frequency it occurs at. if that is known, then possibly i could filter out all the "noise" and just hear the detonation. i just dont know how to find out what frequency range it falls into.
more thoughts???

wait so you would run the vacuum line into the passenger compartment and hold it up to your ear with one hand while you're doing a 4th gear 100 mile per hour full boost pass. Somehow I would think listening for detonation in that way might be difficult under those circumstances.

No, this takes a team effort. One guy drives the car and monitors the air/fuel ratio(guy running the dyno), one looking at the datalog and makes all the tunes(falcongsr), and one to look at the boost gauge and listens for detonation.(me or direp).

sounds like a plan but i like the radio idea for street tuning.

art, im sure my dad would know how to make it work. im sure theres a way to hook up an auxilary input to a stock stereo.

You could probably make it work using one of those cell phone devices that let you talk hands free and pump the conversation through the stereo on one of the FM channels, it wouldn't be added on top of the music though.

I think we could use an FM modulator. Im not sure what it does but I think it does what we want it too. haha
