Knock sensor setup for Nissan RB26DETT

Hi!

Currently I'm working on my calibration for the RB26DETT engine in my Skyline R33 GTR.
This engine has 2 knock sensors, one for each "bank", so cylinders 1-3 are sensor 1 and cylinders 4-6 are sensor 2.

I'm using an "output offset" of 1 in the ignition outputs configuration.

Is the sensor configuration I used correct?
Or do I need to change the correlation of knock sensors to ignition events because of the output offset?

Thanks!

EDIT: Can't attach any picture, because the quota has been reached?!

Maybe you have to resize your Picture, so it isn't so big (Megabyte)

This is the current config.

It would be very helpful to know, whether the output offset in ignition outputs is important for knock sensors as well?

Knock Frequence is wrong

No. Ignition offset only changes when they fire. Basically 123456, is with an offset of 0. Then if you change the offset to 1, it'll fire 234561

Hmm, you are probably right, but take a look at this posting from Jadzwin.
He proposes to change the knock sensor order because of the output offset. So which way is the correct one??
