its detects detonation I think. I think it detects when your car is overfuelling or something like that. Basically a detector that helps prevent engine damage

It a device that listens to the engine and relays any excessive noise in the form of lighting up LEDs. Useful bit of kit for a modified car.

a knocklink is just a pulse sensor with led`s shwoing the outcome.

alot of vibration thru the sensor makes the led`s illuminate more.

thing i find with mine is, when at full chat engines vibrate anyway so its hard to tell if its pure pinking or just normal engine movement

The Knocklink is a effectively a warning gauge for detonation that occurs in the engine.



It's very old technology and the new kid on the block is this:

KS-3 Knock Analyser - Knock Detection System. Complete Kit - Knock Sensor Included.




"What is it?
The KS-3 is probably the most advanced Knock detection system on the market. The KS-3 actively filters and processes engine signals using a dedicated knock microprocessor. These signals are processed and displayed on a wide angle clear LCD display.

How does it work?
The KS-3 monitors engine knock levels and can be configured to alert the driver via a visual and audable warning. The KS-3 can be used as a hand-held device or permanently mounted to the dashboard. The KS-3 is configurable for frequencies between 6 and 9 kHz. The system includes high quality Bosch Wideband Knock Sensor, Sensor Plug, Shielded Signal Cable, Mounting Kit and Power Supply Cable.

Installation
The KS-3 has been designed to be easy to install, reliable and affordable. The KS-3 comes as a complete kit containing everything necessary for the installation. A high quality Bosch knock sensor is included and is linked to the main unit via a shielded signal cable. Installation is very simple: Mount the sensor, connnect the signal cable and connect the power cable.

What is Knock?
Knocking or detonation occurs when unburnt fuel in the combustion chamber explodes instead of burning in a controlled manner. When engine knock is occuring the pressure in the combustion chamber rises dramatically to levels that can destroy engine components in a few seconds.




Configuration
The KS-3 is very simple to configure. The most common question we are asked is what frequency should I select. We now have an online calculator that will estimate the knock frequency for you. Use our Knock Calculator to estimate the knock frequency of your engine.

Why should I choose the KS-3 over other Knock Detection devices?

The goal was to develop the most advanced knock detection system available. The KS-3 has taken nearly three years of develop in conjunction with one of the UK leading tuning companies. It is the result of many hours of dyno and track testing and has evolved into what we believe is the ultimate knock detection system.


The choice of experts

As used by top tuners including Zen Performance and Andy Forrest Performance "

There is a Group Buy on these running now: https://www.scoobynet.com/group-buys...ml#post7913427
