Knock monitor

[dbbob1987]

I was just curious if anyone knew a good place to look for instructions on constructing a knock sensing system for a cbr600rr, or if there is a sensor already available that can be used instead. thanks

Stock 07+ 600RR's already come with a knock sensor. The 'system' part is the kicker. You have to know what to do with the voltage especially since it isn't the resonant type of knock sensor.

I have never found anywhere you can construct your own. The one I use is made by MSD.

I believe this is the one we made last year.

If you really don't mind paying a decent amount for a full knock monitoring system, Gizzmo's Kmon is really nice. It runs about $750 though.

It'll all depend on how sensitive and accurate a system you need. The DIY kits would defiantly be more friendly to you pocket and may be all you need.

You can find the proper, quality equipment for as low as $150 without any DIY needed.

A knock control system for the ECU doesn't make much sense on a race car, it isn't necessary and would be extremely hard to get it working correctly.

A knock detector for the dyno would be a good idea. All you need is a knock sensor from a car - this will bolt on to the motor block. You'll need to buy/build an amplifier for this, and you can feed the signal into the sound card on a computer, or a DAQ system if you have one. Knock frequency should be less than 20 kHz, so a typical sound card should work OK. Find some software that creates a real-time spectrogram from the sound card input, and you'll have a good visual indicator of knock.

awesome, tahnks you guys. yea we looking at setting this up for just dyno use to help with ignition tuning, thanks again!
