IGNITION TIMING ANDENERGIZATION

(1) Along with the improvements of the TDC sensor
andcrankanglesensor signals_theignition
timing control has been changed to the same
control systemas thecurrent 4663 engine.

TIME CONTROL

(21 Other controls are basically the same as those
used for thecurrent 6G72-SOHC engine
