Just bought one of these to try out on the new set up:

http://www.phormula.co.uk/KnockDetection-KS-3.aspx

Spec:

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.

What does engine knock sound like?
See our video clips demonstrating the KS-3 in action clearly detecting engine knock. Towards the end of the demonstration there is an audio sample of knock.

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?
Our 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.

Will let you know what it is like in due course :thumb:

Not to start with, just using this as a failsafe on my car when I havent got my trusty det cans on.

certainly looks like it will do the job and looks smart aswell :lol: unlike the knocklinks

I noticed they sell a laser detector/jammer as well... :whistle:

I have to say though the whole tuners kit and knock display linked together looks a cracking bit of kit!!

Look forward to the writeup :thumb:

Forgot about writing a review of this but here we go....

Installation is a doddle - the supplied knock sensor just bolts to the block and feed a bright orange wire back into the passenger compartment and plug into the unit. The unit is powered by a cigar lighter adaptor so no wiring needed for muppets like me :thumb:

There are settings for the frequency that the knock is to listen out to. The std setting seems to pick up background noise on my engine that wasnt knock (as checked by headphones/det cans and the ecu itself) so once set at the right level it ties in exactly to what is heard by both normal methods.

A warning level is set (in my case at 50) and once this is exceeded a very noticeable alarm is sounded and the units flashes too. I was worried that I wouldnt hear this in my car but even at Donington with crash helmet on it was noticeable enough to take appropriate action.

A very neat unit that does what it is meant to - 9.5 out of 10

Nice one Duncan,

This sounds like a must have bit of kit. I suppose indirectly you could use it as a variable gearchange light too.

Sounds to me like i should be contemplating this, with cans & amp, along with a wideband which i still haven't got yet.

Excellent!! :thumb:
