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.
