I recently learned that there is something called "DET CAN" which is basically a "Knoking" detector. As far as I was able to investigate, there are homemade ways to do it, it doesn't seem complicated, but I wanted to know if an instrument for vehicles is already coming or if it is something that is only done in-house.
Any comments or suggestions about it?
