AKU 1.7 SDI & N108: Specs & Info

Hi.

I have an AKU (presumably a type of injection system) that injects a very aggressive 27 degrees before top dead center.
(Awesome sound, that trekker ).

The N108 is not responding to the basic settings in block 004.

It sounds like a fairly simple issue, probably a faulty N108 sensor.

Sure, here is the translation of the text from German to English:

"NUR:"

Why doesn't the PWM duty cycle change in block 004 if the device is supposed to oscillate between late and early?

It remains at 54%, even though "late" and "early" alternate in field 2?

Shouldn't the actual start position remain the same in case of a defective valve, while the PWM signal fluctuates up and down?
