It works! Only tried to read the fault codes this evening, didn't try out the other functionality.
Ezk just showed 111, so no faults
Ecu showed
311- no speedo connection. I didn't think this mattered so didn't connect it up, but I found this thread this evening:

And since I have a speedo late enough to have the spade connector on the back of it to connect to, I'll connect it up to pin 34.
311 - fuel trim too rich or too lean (I know that's it's waaaaay to rich) and suggested fault is wiring to lambda sensor which I can certainly go over and check.
232- fuel to too rich or too lean, suggested fault leaking injector. I don't think this is the case as at the start of this troubleshooting I took the plugs out and they're all ludicrously sooty and black, but uniformly so suggesting that all the injectors would have to be leaking if that was the fault.
I think the fault lies with the lambda sensor or its wiring so shall look at that first.
