Hi

Thanks, though rev counter still not being displayed:

Method I am using as follows:

Turn kill switch off,
Hold select and reset,
Turn on ignition, Diagnostic screen appears,
Press select to toggle to CO mode,
Hold reset and select to enter CO mode,
C1 appears at bottom of screen and a smaller 0 appears up and to the right,
Switch on kill switch,
Crank engine.

At this point, my LCD screen returns to 'normal' reading speed, trip and odometer.
