Hello! I'm searching for a good and safe knock detector. To use at the dyno, only to detect knock, retarding will be done by remapp the ignition.

Does anyone have experience with the knock sensor at the middle of this page:

I also found this one:

The normal safeguard is not an option for me, I need to use this for several cars (not only Honda), and installation is to much work.
Maybe the 'Knock Finder Dyno Timing Controller' is an option for me, although
this one retards the knock, and I dont want that! I also cann't find out whats the price..

All info is welcome!

 

Anyone???
