An "E4" fault diagnostic will be generated on the DDT if the parameter is changed during engine operation. This fault will not cause the engine to shut down. Press the "CLEAR" key on the DDT in order to return to the normal display. Speed Sensitive Timing Maps

The desired timing parameter allows the customer to electronically program the ignition spark timing of the timing control system. The desired timing is programmed with the DDT. The value can be changed when the engine is running or when the engine is stopped. The value that is entered for the Desired Timing is the ignition timing when the engine is operating at the rated speed. The actual ignition timing at any instance may be less due to the selected speed timing map, the engine speed, or the detonation activities.Note: The minimum programmed value for the desired timing is 20 degrees less than the magneto calibration timing (manual timing mode). The maximum programmed value is six degrees less than the magneto calibration timing.
