Hello DIY'ers

Le me introduce myself.  Paul in Pasadena, working on turbo
charged audi applications.  I have been doing all my own work
and have my 2.15 liter motor running at about 250 HP and
16 pounds of boost.  I would like to progress further but need
to have knock sensing to do so.  Has anyone worked up a DIY
solution to this potentially expensive option?  I understand
how to mount the sensor, but am pretty cluesless about 
knock sensor output wave form and sensing circuits.  Thanks
in advance.
