1Remove the main seat.
2Lift the front of the fuel tank up and
use something to keep it propped up.
3Route the PCIII harness down the
right hand side of the bike. Route the
PCIII harness underneath the fuel tank
bracket (Fig. A). The bolts that hold
the fuel tank bracket on will need to
be loosened to allow room for the
PCIII harness to fit underneath.
Tighten these bolts after the installa-
tion is complete.
4Unplug the connector from the throt-
tle bodies to the main wiring harness
(Fig. B). This is the 12 pin GREY
connector.
5Plug the PCIII connectors in-line of
the stock connector (Fig. C). Make
sure these connectors are postioned as
to not interfere with the fuel line
when the fuel tank is installed back
into position.

6Crimp the supplied wire tap to the
WHITE wire of the ECU (Fig. D).
This wire is from the smaller of the
two ECU connectors in position 5.
Note:The wire location is numbered
on the back of the connector..
7Connect the GREY wire from the
PCIII to the wire tap (Fig. E).
Note: It is recommended to use dielectric
grease on both of these connections.
8Attach the ground wire from the PCIII
to the negative side of the battery
(Fig. E).
9Install the PCIII to the top, rear part
of the ECU using the supplied velcro
(Fig. F). Make sure to use the alcohol
swab to clean both surfaces before
attaching velcro.
Tuning Notes:
This bike uses a fly-by wire system, so conven-
tional tuning can not be performed for all RPM
and throttle ranges.
The GREY wire from the PCIII is attached to the
throttle blade angle sensor of the throttle bodies
which is NOT directly correlated to the throttle
grip position. Because of this when setting the
throttle position in the PCIII software we recom-
mend on resetting only the closed position after
the bike has completely warmed up. Use the
arrow key (<) next to CLOSED to perform this
step and then click OK. Do not try to set the
OPEN position unless you are on a dyno and
above 9000rpm.
You will notice that in the maps there are not
detailed values below 7000rpm at 100% throttle
and below 5250rpm at 60-80%. This is because
the throttle blades will not open more than 60%
below this RPM range no matter how much throt-
tle input is given. Therefore this area can not be
tuned.
