THROTTLE CABLE
ADJUSTMENT
Fully depress throttle lever. Lever must touch han-
dlebar grip.
1. Must touch handlebar grip
Ensure throttle plate is fully open.
Adjust cable to obtain a gap of 0.75 mm (.030 in)
between throttle lever stopper and bracket on
throttle body.
THROTTLE POSITION SENSOR
(TPS)
This adjustment is very important. The setting of
the TPS will determine the basic parameters for all
fuel mapping.
NOTE: Adjustment must be done each time the
throttle position sensor (TPS) is loosened or re-
moved.
CAUTION: An improperly adjusted TPS may
lead to serious engine damage.
The adjustment of the TPS is performed using the
MPEM programmer.
CLOSED TPS
To perform this adjustment, proceed as follows:
Using VCK
Use the VCK (Vehicle Communication Kit) (P/N 295
035 844) with B.U.D.S. software. Look under the
SETTING section to perform the Closed TPS ad-
justment.
Using MPEM Programmer
Access the BOSCH SYSTEM in the MPEM pro-
grammer. Then, select ADJUSTMENT in the sub-
menu.
Choose CLOSE TPS in the ADJUSTMENT menu.
The screen will display the actual adjustment of
the TPS in degrees and it will also offer to adjust it.
CAUTION: Do not select “YES” until the idle
speed screw is loosened to allow the throttle
plate to close.
Loosen the lock nut of the idle speed screw.
Loosen the idle speed screw until it does not con-
tact the throttle plate stopper.
Loosen the adjustment of the throttle cable.
1. Idle speed screw
Depress throttle lever a few times and ensure
throttle plate is completely closed.
Selecting “YES” will instantly readjust the close
throttle position adjustment to the new setting.
NOTE: If the ECU is replaced, the TPS closed po-
sition must be readjusted.
IDLE SPEED
Access the BOSCH SYSTEM in the MPEM pro-
grammer. Then, select REAL TIME in the sub-menu.
Turn idle speed screw approximately 3 turns from
the point when the screw end touches the lever,
or until the TPS idle position reads 6 - 7.
For a precise adjustment of the idle speed, it should
be finalized in water.
Idle speed in water is 1500 ± 100 RPM.
