Vems knock detection, is it good?

[Jonas_R]

You got a link to the KLM knock unit?

[peter_jensen]

We have tuned a lot of Subaru’s using the KLM and it’s working nice. If the KLM is adjusted correct and you got the big red diode light you can be 100 % that’s knock.

Jonas: The KLM is made by me and friends so I relay haven´t no link to give you but if you like the unit you know ware to contact us.

peter,how do you calibrate the klm unit?

[peter_jensen]

Simple run the engine at high rpm and low boost then adjust the potentiometer on the back so the too green diode´s light up. That will normally be it.

A80Avant you need to reduce the boost at 3000-4700 (1.2 bar) and be careful with too much ignition (12-18 degrees) ore you will have knock and kill the engine. yes what you have heard is knock 99%. reduce all parameters at your max torque and test again in gear 6. ps. use Vpower 99


Tnx Peter

Can you re-use the OE Audi knock sensors on the engine with the KLM unit?

[A80Avant]

peter, i always use BP97 octane here in the UK, + water/meth injection from 1bar of boost thereafter.

i will try and do more tests today

Yes you can use the oem knock sensor

I would be interested too

[A80Avant]

peter i have made some changes and now that sound is gone.made the mixture a bit richer and the spark lower.

could you please post your boost configuration settings please? im having some issues in the control of boost,and at the moment i dont want to go to an aftermarket boost controller.

[Jonas_R]

I would be interested in one to depending on price

Vas: install your KnockSense unit. It will tell if you have knock at low to mid revs (will most likely light up at high revs though, since it is not rpm compensated). In the Golf, it is dead quiet on ethanol, but if I have to use old time fuels like 99 octane, it lights up like a x-mas tree.

[A80Avant]

i think i will try that out eventually and see what happens

[Jamo]

So how many of the community are using and have got knock control working with the VEMS ecu and the 3B/ AAN / ABY / ADU engines?

[GazzaG60]

eacy way to check for det/knock

pop a plug, look for white dots. shine a torch down the plug holes, look for piston pitting.

the knocklink works pretty well, problem on a subaru is 3rd gear noise lights the full lot christmas stylee.

they use bosch sensors so fit it well away from the gearbox and ideally over a coolant passage as per factory ones.

its setup on my ecu jamo but im no big believer in knock protection as you will have gathered.

det cans (earphones) are the way to look a ****-ed but have a safe car. you can never account for bad fuel though and you dont know when you will have it.

i tuned for tesco 99 and try not to run anything else. i see no real change on ultimate but its not as good on vpower.
