Would you say that the next step should be to redo the timing with a new chain and tensioners?
Hoping that solves the noise issue at least. If the DTCs persist, then the old chain/timing/tensioners could be excluded from the list of potential causes...
Also, I've read that there has been a TSB for sensor clearance, probably also worth checking right?
BTW finding a local shop with any experience with FA motors has been difficult - even the official Subaru dealer/service said they have never done this sort of work when I reached out to them for a quote.
Could you please explain a bit why a new ECU would be needed? Just trying to understand this. How is that required after a purely mechanical repair?
Is there no way to reset/flash the ECU back to 'factory' settings?

I'd say, it would be a good idea to verify timing. It's possible you have timing off a tooth on one, or multiple places, that could potential cause both those codes. There are two chains, 4 cams, plus the crankshaft sprocket. A lot going on in there.
