INDEX 2.0 CONNECTION OF THE INJECTORS CUT-OFF WIRING. Verify the polarity of the injectors acting as follows: Disconnect all connectors of the original injectors, Prepare a multimeter to measure the direct voltage with full range equal to 20V and connect the negative lead to the ground, Place the positive lead on one of the contacts of the connector injector, Insert the panel and check on the multimeter the measured voltage value. -

If the program does not connect, an error window appears. At this point, verify: - the connection of the serial interface; - that the control unit is connected to the battery and to the ground; - if the under-key has been disabled for more than an hour, to connect, it is necessary to enable the panel for some seconds of to star the car. -

On the switch, it is therefore possible to see the following changes: Reserve = LEVEL value when the LED of 1/4 switches off and the reserve one switches on. Reference 1/4 = LEVEL value when the LED of 2/4 switches off. - Page 16 INDEX • EXTRA-INJECTIONS SENSITIVITY. The EXTRA-INJECTIONS are very short injections performed additionally to the normal injection and are carried out during the petrol feeding, usually during acceleration, to enrich slightly the carburetion increasing the engine yield. The extra-injections can be recognized by observing the signaling LED or the movement of the point.

Page 21: Self-Calibration
INDEX 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. - Page 22 INDEX During methane autocalibration you must store the maximum gasoline injection time on idle. So we need to press the accelerator pedal 4-5 times. Between an acceleration and the subsequent, wait that the rpm are stabilized around at the minimum value. After having concluded the SELF-CALIBRATION test the car with gas feeding verifying that it works correctly and correct, if necessary, the carburetion acting on the map as previously described.
- Page 23 INDEX 8.8 SAVE CONFIGURATION. In this submenu it is possible to save in a fi le all calibration parameters set in the menu “car confi gura- tion”. This fi le can then be used to confi gure other control units installed on cars of the same model and with the same type of fuel, METHANE or LPG.
