Base Ignition Angle🔗
Indicates the base ignition angle to be used when the engine is running (in degrees before top dead center). This is copied from the currently-selected Base Ignition Angle Map.
To form the Ignition Angle Request sent to the Ignition Target Demand module, this value is added to two correction values:
- An Engine Coolant Temperature Correction calculated by multiplying Ignition Angle ECT Correction by Ignition Angle ECT Correction Multiplier.
- An Intake Air Temperature Correction calculated by multiplying Ignition Angle IAT Correction by Ignition Angle IAT Correction Multiplier.
