Trimmer Operation On The Electronic Control Unit Type Iaw 16M For Co Regulation - MOTO GUZZI Daytona RS Workshop Manual

4) Reconnect the connecting rod between the two throttle bodies.
5) Adjust the throttle bodies with the adjusting screw «C» - Fig. 12-12 and Fig. 12-13 of the left body until a
voltage reading of 378mV ±10mV on the potentiometer is shown.
6) If a right throttle body is present, adjust the screw «C» until it touches the butterfly Fig. 12-12 and Fig.12-13.
7) Rise the oil temperature to 100 °C ± 10°C.
8) Open by one turn the by-pass screws «E» - Fig.12-12 and Fig.12-13 of both throttle bodies.

9) Check with a gas analyser that the CO content of the exhaust gas is between 1% and 2%.
10) Connect a vacuometer to the taps of the induction manifolds.
11) Adjust the balance of the two cylinders by the synchronising screws of the throttle bodies.
12) Check that increasing the RPM the depression balance between the cylinders is maintained.
13) Check that at the minimum the RPM is equal to 1200 ± 50 RPM.
14) Use the adjusting trimmer on the electronic control unit so that the CO content of the exhausts corresponds
to the values in the table above.
IMPORTANT
The maximum difference of the values must be about 3% for the CO value and about 7 mbar for the depression.
12.7 TRIMMER OPERATION ON THE ELECTRONIC CONTROL UNIT TYPE IAW 16M («1» - Fig. 12-14)
FOR CO REGULATION.
The trimmer for the CO adjustment is located on the electronic circuit board of the I.A.W. 16M control unit and
can be accessible by removing the rubber cap under the sticky label.
To rotate the trimmer a 2mm plastic screw drive is necessary.
WARNING
The use of metal tools on the electronic control unit board can seriously damage the circuits.
The trimmer rotation span is 270° therefore rotating the trimmer clock wise 135° from the centre position, the
maximum "lean mixture" is obtained; and by turning the trimmer 135°anticlock wise the maximum "rich
mixture" is obtained.
WARNING
The rubber cap is not water proof therefore the of the sealing MOTO GUZZI adhesive is compulsory each
time the cap is removed.

NOTE: The original adhesive has a red brand
name Moto Guzzi.
The Moto Guzzi spare part (code 01732001) is
available and has a green brand name.
The CO regulation trimmer is operating at the
minimum RPM only and its influence is measurable
up to 3000 RPM.
Therefore if an adjustment has to be done in presence
of major modifications to the exhaust system of the
engine, the EPROM the electronic control unit has to
be replaced in order to keep the CO values in the
specified range.
