table is a function of speed and load, and is calibrated manually or adapted as a
multiplier on base fueling. This means that a value of 1.00 equals the calibrated base
fueling and no change is being applied to the end pulse width of the injector. A value of
1.10 equals 10% more fuel is being delivered than is mapped to make the actual AFR
equal the desired mapped AFR. A value of .93 equals 7% less fuel is being delivered, and
so forth. The map allows a typical range of values between .700 and 1.400; if the map
has values near either of these limits, you should adjust the VE map (Speed/Density
mode) or Base Fuel Map (Speed/Throttle mode) to deliver the required fuel the Air/Fuel
Map is asking for and bring the CLC mapped value back near 1.00 so that the O2 sensor
is not limited in its authority to correct for fueling related changes.
If you are running Speed/Throttle control mode - you can apply the adaptation in the
CLC map to your Base Fuel Map to bring your open loop fueling pulse width into tune by
using the "Apply O2 Adaptation to Base Fuel Map" function under the tools menu. You
may need to do that several times if the CLC map reaches its upper or lower limit for any
cell. In Speed/Density mode, you need to adjust the VE map to prevent the CLC map
from being near its upper or lower limit. For more information about closed loop control
or adaptive VE using mass airflow, see the Help section on Adaptive Tuning .
