LOL, can of worms, I'll answer you, then sit back and wait for Pete Lewis to come alomg and rubbish my answer

Basically, knock, pinking, pre-ignition are all the same thing, the mixture in the cylinder is exploding at the wrong time. It should go off at just before tdc, but can, for a variety of reasons, go off before, with resultant engine damage.

A knock link has a sensor bolted to the engine block which senses any extra noise. When it does so, it lights a series of LED's according to the AMOUNT of knock it "hears", with a large, very bright, red one to warn you to take your foot off, if it gets too bad.

They are relatively easy to fit, takes about an hour all up, with time to think, drink coffee etc, but aren't the nicest looking gadget.

Some folk have rewired the box of tricks to put the LEDs outside it, and then fitted them around the instrument binnacle, for example. I keep meaning to do it................

They are devices to monitor knock/det. It can let you know when something is not quite right (bad patch of fuel, dead MAF etc). It's highly important to monitor knock/det in any mild tuned and upwards cars.

Knocklink is the (very much) older gadget and the KS3/4 Knock Analysers are the new and more advanced pieces of kit.

KS3 Knock Analyser adds the following over a Knocklink:

* Audible (as well as visual) alerts
* Peak hold
* Backlit LCD Screen
* Bar graph/numerical display
* Quality Aluminium case
* Selectable Frequency

Bit of difference in price: a Knoclink can be had for £110, whereas the one above is £175 inc discount. Mind, the more expensive one does seem to include a knock sensor, the cheaper one doesn't seem to, so maybe not that much in it.

You pays your money..............

I bolted my sensor on the near side of the manifold.

What ECU does the OP have. May be a bit redundant if they have one that can flash the check engine light in the event of DET e.g. Simtek/Apexi etc..?

Best place for the knock sensor is bolted to the top of the block. There is a space on the near side, near the back, on top of the block, mine had an unused M8 bolt there, or threads for one, I can't remember which now. You can reach down and bolt it in quite easily.
