Load Dependent
Fig. 81 Load Dependent Ignition Timing Control:
*** UPDATED BY TSB # 1085791 Oct. 85
When the engine load exceeds a predetermined value stored in the ECU, the
ignition timing will be retarded 6° for all cylinders at the same time. The timing will advance again in 1° steps per engine revolution when the load has decreased or levelled off. See
Fig. 81 for a chart of the actions performed.
