Usually setting is not necessary.
Adjust in the following circum-
stances:
S When hunting occurs, increase 0.00 to
1 00 A 5 C8-08
AFR Gain
When hunting occurs, increase
the set values.
S When responsiveness is low, de-
crease the set values.
Change the responsiveness in 0.05
units at a time, checking after each
change.
