 8.7  SELF-CALIBRATION 

In this section, it is possible to perform the automatic calibration of the gas control unit in order to obtain 
a averagely correct carburetion of the car during the gas operation.
Before starting the self-calibration procedure it is necessary to verify that the car is in good petrol fee-
ding conditions, since the gas feeding system bases on the petrol one.
By pressing the push-button “Self-calibration” the following window will open.

To perform the self-calibration follow these instructions:
1)   Start the car with petrol feeding.
2)   Start the self-calibration procedure by pressing the key ENTER and follow the instructions given 

on screen.

The system checks the operating time from the time of starting the engine. If the engine has been star-
ted recently the software will display the following windows.
