3.Second gas map
Only the first file is selectable
and active when you start a new
map, while the other two are automatically
activated by the program
itself. Fit the end of petrol selfmapping
begins the gas one. All
these files can be selected and
activated by the user when he
decides to continue a previous
stopped self-mapping, where the
petrol map processing was carried
out. While some operation points
are acquired in the same cell, its
colour changes from red to yellow.
This indicates that operation point
has been acquired with few points
but it can be used by the extrapolation
algorithms which calculate
the complete map (see picture
4.21). Going on in acquiring operation
points in the same cell, the
colour becomes green indicating
the acquired points are enough for
a good map. When the number
contained in the cell achieves the
maximum (for example 50), the
next acquired point will be not
memorised and used to develop
the final map; also the number in
the cell does not increase anymore.
A good map could be obtained
by acquiring more cells as possible,
avoiding to leave a big area of
the map without acquisition (red),
for example full load or high rpm,
etc.) The ideal situation is to obtain
a map with many green points for
all MAP and rpm values (i.e. see
picture 4.22).
The points acquisition can be
stopped anytime (for example if
traffic conditions are averse) click-

ing Stop at the bottom left (picture
4.21) and started again clicking
the same key (the writing will
change into Start – picture 4.22).
When the table contains
enough well distributed green
and/or yellow cells, it is possible to
continue the interpolation of the
missed points (red) with the creation
of the final petrol map. To do
that, stop the points acquisition
clicking Stop and then Compute at
the right bottom of the screen (picture
4.22). This operation begins, if
25
possible, the acquired data processing,
creats the petrol map, an
initial gas one and transfers everything
in the ECU. At this point the
procedure moves to the screen for
the first gas map.
4.2.1.8.2 GAS SELF-MAPPING
At the end of the petrol map
phase, you can start the gas one.
The gas self-mapping is divided in
two steps:
