For those who have used one (part# 8964) how sensitive was it?? I have just bought one and it only shows knock when I can actually hear it anyway!! I have the sensitivity up full. Does placement in the block have much to do with the sensitivity?? The instructions say to run your motor at 2500 rpm and adjust the sensitivity until the first green led comes on. I dont think I get anywhere near that happening. Could I have a faulty sensor??
