For example TurboXS or any other?
It connects to factory knock sensor or into separate knock sensor (sold separately) and flash to alert you to the knock...
So, its a shit or realy device which can alert the knock in cossie engine?
Or may be you have some other method to knock monitoring...
Thank you!

 

I'm using KnocksenseMS connected to my management. When knock is detected, it blinks a led in my stock rev counter, decreases the advance by a few degrees and increases the fuelling a little. I've had some trouble with setting a threshold level that would work throughout the rev-range with the enormous amount of CVH valvetrain originated noice.
