According to the factory manual, the crank signal should be an oscillating signal but in RR logger only the cam position sensor is oscillating. I'm trouble shooting an issue where the #3 and #4 injectors aren't pulsing directly AT the ECU with only a P0600 DTC on a EJ20x motor/ecu setup. Could any of you fellas confirm that the crank signal, as read by RR, is showing to be normal in this screen shot?

it's normal. logging is waaaaaaay too slow to see individual crank/cam sensor signals.

Oscilloscope.. nothing less than that.

Good to know, thanks for clarifying that for me fellas. One additional question, is it normal for the cam position sensor signal to go flat whenever EITHER one of the two powered cam position sensors are unplugged? These are the cam position sensors located towards the back of the head....the front cam position sensors located behind the cam gears have no effect on this signal in RR.

I've gotten the oscilloscope reading of the camshaft lh, rh, and the crankshaft signal. I have the detailed logs on a spreadsheet but graphed a quick few revolutions for visual interpretation. The only thing that strikes me as odd is that one of the cam position sensor value appears to be inverted but have seen several wave forms online in the Subaru family which confirm this to be normal. Does anything look odd with these inputs to you guys?
