I believe the unlock code S&S are referring to was actually embedded with the Stage 2 map. The update unlocked the ECU, flashed the Stage 2 map and then relocked the ECU.
If this is wrong and you can get an unlock code out of Morgan then you will become a very popular chap as many of us have spare locked ecus from when we purchased an unlocked or replacement ECU as part of the 569 installation.
Do let us know how you get on with Morgan.
