The ECU will adjust the spark timing when the
engine is idling to help control the idle speed. This
number affects the aggressiveness of the function.
Maximum amount the spark timing will be adjusted
(crankshaft degrees) to smooth idle rpm.
Spark timing (crankshaft degrees) when the throttle is closed.
Spark timing (crankshaft degrees) when the throttle is closed.
Maximum TPS setting (percent open) where the
Closed Throttle Spark table is used. Above this
point, the normal spark timing tables are used.

Performance Enrichment mode is a special “engine
preservation” mode designed to help keep the motor
from being destroyed. After a period of time at wide-
open-throttle, the ECU can add extra fuel and reduce
spark timing. This table indicates the desired AFR vs.
time. The longer the engine is in this mode, the more
the AFR should decrease (get richer).
Spark timing while in PE mode (crankshaft degrees)
Once the engine is operating in PE mode, if the
RPM drops below this level, it reverts back to
normal mode.
Engine rpm must be above this level before
entering PE mode.
Once the engine is operating in PE mode, if TPS
drops below this level (percent open), it reverts
back to normal mode.
The throttle position must be above this level to
enter PE mode.
