20.3 The increment of timing change is dependent on the number of holes or teeth
being sensed. The minimum timing change is defined as follows.
The timing increment is “90/N” degrees, where N = no. of holes or teeth.
Example: 90/360 = 0.25° min. timing increment.
20.4 Global spark timing is determined based on the sum of several spark retard
components which include manual retard, current loop retard, RPM retard, and
1 step retard. The range of total retard is limited to 255 X timing increment. When
the sum of all retard components reaches 255 X timing increment, the actual
timing will be at the retard limit.
21.0 SELECTION OF GLOBAL TIMING MODES
21.1 Several options exist with regard to global timing modes. Once the global timing
mode menu is entered as described below, the status of each option can be
viewed and changed.
