AUTOCALIBRATION
The calibration of the control unit can be done in this section so that correct carburetion of the vehicle can be achieved when running on GAS.
Before starting the automatic calibration procedure, verify that the vehicle runs smoothly on petrol, because the injection is based on the
Petrol one.
Follow these instructions to proceed to the automatic calibration:
1) Start the vehicle on petrol and wait for the engine to reach its normal operating temperature (approximately 90°);
2) Start the automatic calibration procedure by pressing the ENTER key and follow the instructions shown on screen.
When the engine revs have reached the value specified on screen, the control unit will perform several switch from petrol to gas.
The engine’s revs will probably drift during the first stages. It is important to keep the accelerator pedal steady even if the revs drift, without trying to correct the revs.
If the engine stalls during the automatic calibration procedure, enter “VEHICLE
CONFIGURATION” in the “F1 Change-over” section and select “Reset ecu and go to base parameters”. After resetting, restore the settings for the parameters in “ VEHICLE
CONFIGURATION”, if necessary.
• Check the nozzles size !
Return to AUTOCALIBRATION and start the automatic calibration procedure again, as described above.
- Try the auto-calibration while driving on the road, if it seems that it’s difficult to complete it while on idle.
After completing the AUTOCALIBRATION, try the vehicle on gas and verify that it runs smoothly.
Note:
Starting from software version 4.1.0, the default starting injection time has been changed from
4.2ms to 3.5ms. This should ease out the autocalibration process, most of all with Range
Rovers, that had some troubles during this process in the past.
