technically, any value of knock is dangerous. But the figure I have in my head is 130 for some reason.

Ignore it on the commander anyway, unless you are 100% confident your sensor is good. Otherwise it will pick up road noise, exhaust, dump valve, heavy bass, basically anything within range of the microphone and tell you it\'s knock.

For what it\'s worth mine regularly sits at around 150-160 which is waaaaaaaaaaaay too high, but I know the map is good so all is well

If you are totally stock then its a good tool.
If you are modified with a non stock exhaust, ignore it as its totally worthless sensor as it picks up all manner of noises, and if have real knock your engine would be toast by now

lol cheers for the response guys

pottering around under 3k rpm, knock sits at 0.
its pretty loud exhaust and not stock. seen it raise to 4 (peak) though not sure when and what i was doing when it peaked at 4.

i guess i dont need it on the commander
