Hi,
just fitted knocklink to my 93wrx. However, can't seem to get a reading. one green light comes on when u turn ignition on but thats it. just been out in car and noticed that the bottom green light is permently on but very faint. could this mean i have a bad earth??

any help would be appreciated.

 

Have you turned the sensitivity to full?
Dim green light is the norm
DEKA

 

yes sensitivity is at max. how hard should i tap the block to check it? what sort of speed do u need to drive at to get the second green light to come on?


thanks

 

You should get at least one green on full boost towards the top of the rev range. The LED's are often not soldered on properly, you should open the box and check this, it is common!

 

If you just tap the block (not the sensor itself) next to the sensor you should get a few LED's light up, just keep tapping a little bit harder and you should get the red LED to light up. Mine just stays on 1 green LED under most driving conditions.

 

Unless you've done some fairly heavy tuning, or somethings wrong, you should never really see any knock activity. Tapping the block is a pretty good diagnostic, as mentioned

 

Not even one green??? Are you serious?

 

when I used millers instead of NF mine was always flashing green to one orange when it was warm

now I ve moved to NF and cooler plugs, I have to keep checking the knocklink can't even get one green

 

certainly on a daily driver I don't expect to see more than the odd flicker of the bottom green.

 

To be fair, the knocklink never picks up det, but only slight pinking...

Waste of time and money IMHO LOL

 

whats the difference between pinking and det? i was under the impression they were the same thing!!

Did you ever get this sorted? Did the lights come on when you hit the sensor?

NENO

 

I though pinking and det where the same, I just thought the non technical name of "pinking" was due to the sound det made when listening through cans.

 

waste of time and money - I dont think so!!!

 

seem to have it sorted now, boost was spiking and causing the knocklink to light up like a christmas tree. have now fitted hks evc and also added sx performance fuel reg, and walbro pump. raised fuel pressure and everything seems to be fine.

do get the odd green light but only ever the bottom, and to achieve this i have to be having it large on the right foot.
