Connect The Diagnostic Tester - Gilera Nexus 500 Workshop Manual

Injection
Pre-calibration entails regulating the minimum opening of the throttle valve to obtain a certain flow of
air under preset reference conditions.
Pre-calibration ensures optimal air flow for the control of the idling.
This regulation must not be tampered with in any way whatsoever.
The injection system will complete the management of the idling through the stepper and the variation
of the ignition advance.
The throttle body after the pre-calibration has an opened valve with angle that can vary depending on
the tolerances of the machining of the pipe and the valve itself.
The valve position sensor can also assume various fitting positions. For these reasons the mVs of the
sensor with the valve at minimum can vary from one throttle body to another.
To obtain the optimum fuel preparation, especially at small openings of the throttle valve, it is essential
to match the throttle body with the control unit following the procedure known as TPS resetting.
With this operation we inform the control unit, as the starting point, of the mV value corresponding to
the precalibrated position. The control unit will recognise such value as angle 5.24°.
To reset, proceed as follows:

Connect the diagnostic tester.

Set the switch to "ON" with switch in "RUN" and
side stand raised.
Select the functions of the diagnostic tester on
"TPS RESET".

Make sure that the throttle valve with the control is
supporting the stop screw.
