The throttle body is supplied with gas valveposition sensor and is pre-calibrated.
Pre-calibration consists in the adjustment ofthe minimum gas valve opening, to obtain a fixed air capacity in
predeterminedreference conditions.
Pre-calibration allows an optimum air rate foridle management.
Thisadjustment must not be changed.
The injection system will complete the idlemanagement by the stepper and the ignition advance variation.
After pre-calibration, the throttle body has thevalve open with an angle that may vary according to the valve and duct
workingtolerances.
In turn, the valve position sensor may takedifferent installation positions. For these reasons, the mV of the sensor
withvalve at minimum value may vary for different throttle bodies.
For optimum carburetion, especially with smallopenings of the gas valve, it is necessary to match the throttle body
with thecontroller according to the procedure called TPS.
This operation allows setting the mV value inthe controller as starting point corresponding to the pre-calibration
position.The controller will recognise such value as angle 5.24
degree
To reset, proceed as follows:
Connect the diagnostic tester dwg. 020460Y. (see page 9-17).
Set the switch to "ON" with switch to "RUN" and side stand raised.
Select the diagnostic tester menu functions on
"TPS reset".
Check that the gas valve has the control
abutted against the abutment screw.
In this position, confirm the TPS reset
procedure.
Select the "parameters" function and check
that the TPS reset "YES" is displayed.
