Japtastic141 Posted May 10 Report Share Posted May 10 Got myself some hose, ear defenders and copper pipe. Hooked it all up and secured the pipe to the inlet manifold but I'm struggling to pick up any knock noises. Either there isn't any, I'm not picking it up or the general noise of the car/engine/exhaust is drowning it out. Any tips on how to improve this? I fitted some new Bosch sensors a few months ago and still have the gain set to 1 across the board. Quote Link to comment Share on other sites More sharing options...
