New Knock Link Released!

[RAYDEO]

After months of testing and development...

The G4 KnockLink Digital Warning is the only self calibrating, knock warning instrument on the market.

Drive with peace of mind, knowing that your engine is operating safely when using the G4 KnockLink. The KnockLink will show the beginning detonation long before you hear it.

The G4 KnockLink is designed for both street and race use.

 

"Ignition timing can make or break an engine and the effects of too much timing or a bad batch of gas can really ruin your day.

The team at Link has been hard at work with knock detection devices and off the back of the G4 KnockBlock comes the G4 KnockLink.

The G4 KnockLink is a stand alone Knock Detection warning light that is simple to install and actually works. I was surprised at how well the KnockLink worked either with factory sensors or noisy engines - the KnockLink picked up detonation that if left alone would have destroyed an engine.

The KnockLink is perfect as a warning device in all cars for that peace of mind as well as a handy tuning tool."

Typical causes of engine knock: Engine knock is one of the most damaging effects in any engine. Detonation (knock) can destroy your engine in seconds. You need to know when knock occurs, instantly. If knock does occur, the KnockLink warns the driver with a high intensity red flash.

Knock can happen when there is:

• Poor fuel quality Incorrectly rated spark plugs Engine cooling problems Engine management problems
  

What is Knock?

Knock, also known as detonation or “pinging”, refers to the spontaneous combustion of an air/fuel mixture inside the combustion chamber.

The self calibrating, G4 KnockLink will flash to warn the driver of any knock present.

Knocking is induced by excessive pressure within the combustion chamber causing the air/fuel mixture to self detonate. Excessive combustion pressures can be a result of increased engine temperature, high boost pressure, elevated inlet air temperature, lean mixture or over advanced ignition timing.

Tuning for performance and efficiency brings an engine nearer to the point of detonation. To achieve the maximum output and efficiency, combustion pressures must be optimised to create the greatest force on the top of the piston (or side of rotor). This combustion pressure is controlled by ignition timing and mixture.

If the air/fuel charge detonates, a large pressure impulse is created vibrating the surrounding engine structure. The effects of the vibrations can cause cracked pistons, bent rods and damaged bearings. This gives the need to accurately detect engine knock.

The most common way of detecting engine knock is to bolt a piezoelectric vibration transducer (knock sensor) to the side of the engine block. The knock sensor behaves similarly to an audio microphone but converts vibrations rather than audio to an electric signal.

ClubSUB potentially has a group buy avilable, pm me for info.

BTW were looking around the $200-250 mark, maybe less depending on how many orders we can muster.

This is a seriously nice piece of kit

Operation is simple. The colour of the LED represents four different modes:

Dim Blue - KnockLink is powered, waiting for the engine to be started

Flashing Blue - KnockLink has detected the engine has started and is now calibrating

Dim Green - KnockLink is adapting to the engine's noise profile and listening for knock

Flashing Red - KnockLink has detected knock. Avoid large throttle openings, seek professional advice

Instruction Manual

Engine knock is one of the most damaging effects in any engine. The KnockLink warns the driver in the event of knock with a high intensity red flash.

Installation

Installation is simple and requires four wires to be connected.

Mount the sensor as close as possible to the centre of the engine block.

Never share the knock sensor with the ECU.

Don't know a lot about the Link ECU but doesn't the G4 have a anti knock setup anyway?

So this is something you would buy if you don't have a link? Or is it a supporting product for the G4?

[gotasuby]

Only plug ins and extreme have knock and its not a visual disply and it doesn't self calibrate like this. I would be keen but have a knock block g4 at my disposal ;D

[RAYDEO]

This would be high on my list for any turbo Subaru I owned, infact I have already placed my order for 3 of these units. 2 of them are going in standard road going legacys.

+1 fully agree its a good idea on turbo subarus

Hmm ok good to know...

I'm Buying a G4 in the next few weeks, didn't want to double up. Might be keen Ray will PM when I'm home in a day or two.

[pawan]

oh awesome! any one know what the price for one of this is?

[RAYDEO]

Yes about $270, if you not one pm me as we have a group buy going

Not really correct... You can connect a light to an output and trigger it from the knock level, given the internal filtering and adjustable thresholds it is actually more versatile

eg

[pawan]

oh awesome but can only get one next week or so if you guys are doing a group buy then let me know. had one quick question cna this be connected to a g4 for retarding timing when knock is present?

[Bazza-NZ]

Would anyone recommend this to use a tuning device? It would be this or an older Knockblock for now??

I'm in need of a knock device to complete my kit...

Advice on those with experience?

[RAYDEO]

Dunno bout a tuning device but I'd use it in a car indeffinatly

[gotasuby]

A knock block you can hear exactly hpw bad it knocking. This does not. I would go a knock block over this having had experience with both types of device

Cheers Dude

[RAYDEO]

OK LADIES AND GENTS.

We have secured a group buy, my aim is to get orders for 10 units, thus bringing the price down to $212.50 each plus GST

They are a great little unit and RRP is around the $300 mark so lets get on this asap.

PM, email, txt are all fine so get hold of my and lets make this happen!

yeah, but you still need to know what youre listening for... personally Ive neevr been able to hear knock even when i had your headphones on while tuning my RA...

possably because i work with sound every day and my ears anr a little worse for wear hahaha...

still a great little unit.

also theres notihing else on the market this advanced. this self calabrates...

[Stoffa]

Just ordered mine direct, they're out of stock till next week

[Guest]

Ray work your magic lets have another group buy...

[rexxr]

I'm considering this for my built v7 sti, mainly as a tuning tool to compliment the innovate EGT,wideband and oil press/temp gauges. Is this a viable alternative to the knock block for advance tuning?
