That's a really nice project you've got going there  :woot

How did you get round the problem of the ECU bringing in the rev limiter really early as there's no speed being shown by the front wheel ?

The ecu doesn't reduce the Rev limit with the speedo removed, never has, never will.
What it does do is show a fault code once the bike is revved past 10k and continues to show that code until it's reset by turning the ignition on and off.
Whilst it's showing the fault code it can still be revved to the red line!
