Good work Cam.
If you had managed to get TuneECU to talk to the ECU it should have thrown a P1351 error - "open/short circuit - ignition coil 1" which may have expedited this whole process. You should have seen the fault lamp light up at some stage regardless. When you do get TuneECU to talk, you'll have the pleasure of clearing that error
Despite that, you got there, and learnt a lot on the way.
