Yes that is how I read the manual also.
From page 2-11.
The engine may have a poor idle behavior if the control unit is not reset.
From page 9-33
Error: Poor idling after replacing the engine (EFi only)
Cause: Control unit was not adapted to the new engine
Remedy: Delete preset values using the KTM diagnostics tool (see Chapter 3) and allow engine to run in neutral for 15 minutes
I am going to go out on limb here and suggest that this procedure is to calibrate the airflow sensor, that is all.
