IgnTrimIdle
Units:
Ignition timing trim vs Idle RPM error
Description: This table applies an ignition trim as a function of idle RPM error. Negative values
retard ignition timing from the value in the main ignition map, which tends to decrease engine
speed slightly. Positive values advance timing, which tends to increase engine speed slightly.

IdleTargetOffset
Units:
Idle Target Offset RPM vs After Start Time
Description: This table can be used to increase the target idle RPM for a few seconds after
starting the engine. This will allow the catalytic converter to light off earlier for improved
emissions and will also fight a lean mixture from excessive wall wetting from poor fuel injector
atomization.

IdleTPSOffset
Units:
Idle RPM Offset vs TPS
Description: This table offsets the idle target RPM at low throttle angles, to increase the desired
idle speed when idle feedback may still be active. The values are offset from the
IdleTargetTable.
