During cranking the fuel and ignition are not controlled by the main fuel and ignition maps, but
instead by separate tables and options.
The cranking condition is defined by the engine speed options Min RPM and Start Exit RPM. Min
RPM is the engine speed at which the engine is considered to start cranking (typically 50 rpm), and
Start Exit RPM is the engine speed above which the engine is considered to be under normal
running ie no longer cranking (typically 400rpm)
10.1 Ignition
Whilst cranking, the ignition timing is determined by the Start Ignition option. This is set in degrees
and would normally be a low value eg 2 degrees.
