injection type, etc.). As soon as self-mapping starts, the key shown in fig. 4.6-1 will be enabled and
will request to press
start
when the idling conditions with petrol have been reached.
Please note: at the end of the self calibration procedure it is important that the off-set value is
negative, otherwise repeat the procedure and check for any problems in the installation.
On completion of a self-mapping is important to save again. At this point the car is already ready to
be delivered to the customer.
4.7 Map
This section allows having a numerical view of the multiplication coefficients used by the control
unit in the calculation of the GAS injection time.
The table displays on the Y-axis the petrol injection times, while on the X-axis we find the number
of RPMs, (fig. 4.7-1).
Fig.4.7-1
The red-coloured selection displayed on the map identifies the RPMs and the petrol injection times
at which the the engine is running.
Increasing the value of the calculation coefficients (Off set) in the map, while maintaining the
PETROL injection time constant, will increase the GAS injection time, while decreasing this value
the exact opposite will take place, i.e. the system will be leaner.
To change the values, select one or more check boxes on the map and press the "Enter" key; enter
the value to be attributed to the cell and confirm the value with the “Enter” key.
