Im just wondering was your battery charger(assuming its a battery charger as it almost looks like an inverter aswel ) causing the interference to your captures?
and just wondering what were you running with the item in the bottom right of the picture?
Possible sources of interference to your ?
Yes that is battery charger, maybe he makes noise ...Tomorrow I'll record something without him and we will see, good idea.
And the other thing is pwm signal generator ... I used to checking fuel pressure regulator and fuel metering valve.
This is so "lovely" engine that we should make special thread for that and gather all strange and not so strange captures and control logic information.
Fact that it fires injectors even with low pressure is interesting. I will be installing injectors on this engine in few days. Will take a capture to see how it reacts until air is primed out and pressure reached.

I too have had some fun and games with that family of Engines
I have found the Technical Guided Fault Finding and Repair Document for it.
