i have a mk2 fm link ecu and so far its working great. only problem is when i rev up the engine to (almost) the limiter i only get readings of 1 or 2 on the knock readout at around 6000rpm but the manual suggest a threshold of 35?? need to start tuning ignition but want to be sure the knock sensor is working as it should first. maybe there is just no knock? any help would be great.

 

I am having a similar problem. I will be investigating on friday and will let you know what I find. Good luck.
