PRICE DROPPED TO 80$ SHIPPED

The only way to correctly read knock off the knock sensor voltage.

I used it on my Zeitronix dataloggin system to read knock. Can be hooked up to any other dataloggin system that has a 0-5V user input

Here is a graph made by nj1266, show the knock buffer reading knock at the same time as EVOScan.




Here is a couple graph I made using the knock buffer on the Zeitronix ZT2..

The first screenshot has no knock, just the sound of the engine or nosie floor.
Kncok buffer is on the user input (light blue line).



This next scrren shot has an event of knock around 6800RPMs




Here is how to hook up the Vishnu knock buffer to the Zeitronix (or any other dataloggin system with a 0-5V user input).


Pink - to the knock sensor wire (use a ECU pinout to find out what one is the knock sensor- road/race has the VIII pinout on the website)

yellow - to 0-5V user input on zeitronix or other logging system

black - ground

red - 12V power

Blue and white wires are for a built-in O2 simulator, I didnt use it so I dont know how to hook it up

would this work with a turbo xs knock light?

 

You would have to ask them, but the tell the truth, I think the knock light has its own "buffer curcuit" in it.
