We just purchased the PLex tuning knock monitor. Does anyone know a good website with information on how to setup correctly, tips etc.


You are aware that the manual is contained on a webpage found here:

The online manual should cover everything you need to know. My biggest tip would be to start by using the filter closest to that calculated based on the engine bore diameter. This is where I always start, however I'd advise you to test with the other filter settings too and see which one gives you the clearest audio when knock occurs. For example I've found the 10 kHz high pass filter to be exceptional on many engines, but falsely indicate knock in some instances.

Great advise, I already finished the online manual, but any experience tips always help!

can you remove the sensor installed in factory for plex sensor?
