IAC Warmup
Idle RPM
When cranking, there is a minimum amount of
air required to get the engine to start. This air
is controlled by the IAC motor position (“steps”).
When the engine is cold, more air is required. This
table allows you to adjust this relationship.
Once the engine has fi red off it transitions from
cranking mode to “run” mode. During this
transition, the IAC will need to close to keep the
engine RPM from surging too high.
Table indication the initial IAC position (steps) vs.
engine temperature (degrees C). The closer these
numbers are to the actual idle IAC position, the
smoother the initial idle will be. Displacement
changes may require adjustments to this table.
Desired idle speed at various engine temperatures.
Warning: Oil pressure drops as the engine rpm
drops. H-D warns that 900 rpm is the minimum
idle speed to have adequate oil pressure.
GENERAL TABLES
Injector Size
Engine Displacement
Rev Limit
Gear Ratios
Rated size of the fuel injector (grams/second).
Engine volume in cubic inches. (1 cubic inch = 16.39cc)
Maximum engine speed allowed. Testing this in Neutral
will give results lower than expected. Stock valve
springs will limit the usefulness of higher settings.
Gear ratio for each gear (fi rst, second, third, fourth,
fi fth, sixth). The ECU uses this info to know which
gear it is in.
