SELECTION OF ECM TUNING
MAP
In the ECM of this model, there
are three different maps provided,
a standard map and two modified
maps (injection map for slightly
leaner mixture and that for slightly
richer mixture).
Select the appropriate short wire
among those that come supplied
in the motorcycle shipping crate
and connect it to the mode select
coupler. This can change the
ECM setting to the modified map
(either injection map for slightly
leaner mixture or that for slightly
richer mixture depending on the
selected shunt wire).
NOTE: The changeover is exe-
cuted immediately after the
engine has been started.
• Select White short wire (map
for slightly leaner mixture)
when:
1. Raining
2. In highly humidity
• Select Gray short wire (map
for slightly richer mixture)
when:
1. In low humidity
2. At continuous high speed
NOTE: The above information is
provided only as a guide. To
determine the setting, make sure
to check also for drivability and
spark plug firing end condition.
