moving to the right. On the contrary,
in each column the MAP
value does not change while rpm
increase moving down.
Please keep in mind the MAP
value increases (on the same rpm)
according the throttle valve opening
to (that is pressing the accelerator
more); therefore during the
self-mapping we move to the right
on the map by accelerating, shifting
up and looking for hill trial
courses.
To move down the cartography
you have to achieve very high
rpm, for example, increasing the
vehicle speed, shifting down, etc.
In this case, the white column on
the left of the screen, with values
from 300 to 6250, contains rpm
values concerning to each line of
the table. At the same time, the
high white line with values from
125 to 965 contains the MAP value
in mbar concerning each column
of the map. At the beginning the
cells of this table are red and the
inside value is zero “O”.
The cell where you are corresponding
to the current rpm and
MAP collected by the system is
enlarged during the acquisition
(see picture); at the same time
rpm and MAP values concerning
the centre of the cell are displayed
in blue on the border of the table
In the upper cells, indicated as
RPM and MAP, the vehicle real
values are displayed as shown in
picture 4.20. The displayed cell
keep to have value “0” till the operation
points acquisition does not
begin. This acquisition starts as
soon as we achieve the optimal
conditions (reducer temperature,
engine on for enough time,
Pic. 4.19 - Aided Procedure – petrol self-mapping beginning
Pic. 4.20 - Aided Procedure – petrol self-mapping
changeover switch in petrol position,
constant operation conditions,
etc) and the Start key (at the bottom
left) has been pushed. The
value “0” starts to increase as
shown in picture 4.20. The technician
is informing again the map
phase begins through the message
Acquisition in progress (at
the bottom of the screen).
Going on with the description of
the screen shown in picture 4.20,
besides the first two cells at the
24
top left (RPM and MAP) we have
the following information;
• Petrol duty-cycle inj.: shows
the value picked up by the system
in that moment for the
petrol injectors Duty Cycle;
• Lambda 1: shows the oxygen
sensor electric value;
In the upper part of the screen
(picture 4.20) we have three files:
1.Petrol Map
2.First gas map
