So I spent the weekend making my own 'det cans' using a microphone amplifier attached to some speaker cable with a whole fun time of soldering. I'd post some pictures but I'm still new to the forums (under 15 posts) and can't really justify spamming your forums with junk posts until I can provide links/images.
So basically, I'm wondering where the best place to put the crocodile clip where I attached the microphone. I read in some specifications that the standard knock sensors on the RB26DET engine are under the inlet manifold. This is quite tricky to get to so is there any specific place that I should be placing the device? i.e. should the microphone really be touching the block?
I did attach it to as close to the block as possible but there was definitely a lot of background noise, i.e. the sound of the clutch, gear changes and general engine noise. If my understanding is correct, I should hear a crackling/popcorn sound for det?
