+Global retard is an adjustment affecting the timing of all cylinders equally. This adjustment
+can be equated to the manual timing switch of the Altronic II-CPU system. Adjustments
+made as described below will be in effect until another adjustment is made.

+The increment of timing change is dependent on the number of holes or teeth being sensed.
+The minimum timing change is equal to "90/N" where N = no. of holes or teeth. EXAMPLE:
+For 360 holes, the minimum timing change increment is 90/360 = 0.25 degrees.
