I tried both 1.1 and 1.32.

sensor problem is not only for 1 car. it's a problem of all cars.

sensor signal is connected to B10.

what the hell's happening.

I connected the sensor to the headphones and it works just like any other sensor.

What is the value set in knock sensor parameters?
Did you try to increase the gain parameter?

Your settings are wrong, or did you have a 1 Zylinder?
Please post configuration and log here.

Your configuration is wrong.Because you forgot to assign the other three ignition events to the knock sensor input and your gain is very low.

Is it right, that you use only one knock sensor and this is connected to input 2?

Why your signal is gone in the log i dont know, maybe wiring problem? Please check this twice.

Try the following config:

it's obvious that signal is cut off in the log.
wiring has been checked twice. even re-wired. there s no problem with the wiring.

from the same knock sensor, I wired it to the MIC of the computer and I get the typical engine noise.
so, sensor works. I tried with another sensor, too. these are all bosch 1.8T sensors.
result is : same.
