EDITABLE TABLES
INSTRUCTION
SPARK TABLES - CONTINUED
Idle Spark Control Gain 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
Idle Spark Control Max
(crankshaft degrees) to smooth idle rpm.
Front Closed Throttle Spark Spark timing (crankshaft degrees) when the throttle is closed.
Rear Closed Throttle Spark
Spark timing (crankshaft degrees) when the throttle is closed.
Closed Throttle Max TPS
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 TABLES
PE Air Fuel Ratio
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).
PE Spark
Spark timing while in PE mode (crankshaft degrees)
PE Disable RPM Once the engine is operating in PE mode, if the
RPM drops below this level, it reverts back to
normal mode.
PE Enable RPM
Engine rpm must be above this level before
entering PE mode.
PE Disable TPS 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
PE Enable TPS
enter PE mode.
