Axle Ratio
Cooling Fans
Power Enrichment
Spark
Normal Shift Adaptation
Axle Ratio
Adjust only if different gears are installed, and where
necessary. Corrects speedometer and transmission for gear changes.
N/A for Corvette (y-car), please read addendum to manual for instructions.
Cooling Fans
Allows user to change temperatures where cooling fans go on and off.
(Applies only to vehicles with electric fans)
“On” temperature MUST be higher than “OFF” temperature for proper
operation of fans.
Power
Adjust only if vehicle is running rich or lean
as verified by an air/fuel
Enrichment
meter.
Increase numbers if the air/fuel ratio is lean and decrease
numbers if the air/fuel numbers are rich. When adjusting the Power
Enrichment we will allow up to a 5% increase or decrease of fuel trims
at WOT. This translates to approximately a 1.5 point air/fuel adjustment
range plus or minus.
Spark
Adjust only if the vehicle has a spark knock (detonation). Higher number
will advance timing lower number will retard timing. When adjusting
the spark we will allow up to a 10% increase or decrease of timing in
the WOT range. This translates to about a 2 /- range of adjustability.
Normal Shift
Applies to automatic transmissions without TOW/ HAUL mode.
Adaptation
Modifying Parameters - Parameters Explanation
Shift
Adaptation
Allows user to adjust the time delay
between shift commitments, i.e.
quickness of the shift.
When adjusting to a negative
percentage, the shift adaptation
will be shorter, hence a quicker shift.
Positive adjustment will yield
a longer and slower shift.
