ENGINE SPEED
BASE IGNITION ADVANCE
• When the idle switch is OFF
The optimum basic advance is set according to the engine load (basic injection time) and the engine speed.
Cooling water temperature compensation advance
• Warm–up compensation advance When the cooling water temperature is low, the ignition is advanced to
improve warm–up performance and driveability. The lower the temperature is, the larger the ignition is
advanced.
• High temperature compensation advance When the cooling water temperature is higher than 90°C and the
engine load is large, the advance angle is decreased.
Idle stabilizing compensation advance
When the ISC feedback control is being executed, the advance angle is compensated according to the varying idle
speed so that the idle speed is stabilized.
