This might be a dumb idea but a buddy and i at work started to discuss the possibilities of somehow adding a knock sensor or sensors to my viper. i have added srx heads and machined them to modify the squish band and squish angle. i don't have the DCS on my viper as it is an 02 but thought if i could somehow put a sensor on each head and have a dash light that would flash to let me know if it is detonating. I know it would not modify the ignition timing at all since it would not communicate with the ignition module but i would as least be aware of any detonation and then go from there. i like to work on my sled and thought that this would be something interesting to play with. just a thought any input would be great
thanks

Sounds like a good Idea. However, from my experience with cars and Knock sensors, the system is a little complicated. The sensors on cars are a piezoelectric type. This means that the sensor is filled with a type of crystal or ceramic squeezable material. The material will actually produce a voltage when squeezed (or when a knock occurs) and this voltage is sent to the PCM (powertrain control module). When the PCM see's this voltage it will then set a code, which in turn will set a light on(Check engine). Since the occurance of the knock could be in the millisecond range, the light would not stay on. So if you hooked up a sensor directly to a light in your Instrument cluster, the light could only possibly flash. And since the sensors only work at low voltages (either 0-1 volt or 1-5 volts) they knock sensor itself could not produce enough power to make the light function. Another factor of a knock sensor is that it is less accurate with high and fluctuating RPM's, however Yamaha has used their system and it does work, so there must be a way around that.
I would try to find a system with DCS from a SRX or Viper and try using that. The SRX system would probably work better for your setup (especially if you plan on running tripple pipes)
Another sugestion that isn't the same is to get a set of EGT sensors, will not be able to see a "Knock" but prevent melt down from running too hot.
