Every car owner wants to save on fuel, especially in modern conditions. Of course, it is quite possible to realize such an idea if you install gas-cylinder equipment. Moreover, in specialized reputable services, where real professionals work, such work is completed in a matter of time.
Of course, before installing LPG, drivers should understand whether propane or methane is suitable as a fuel for your car’s engine, whether it can shorten the service life of the internal combustion engine as a whole, etc. As experienced experts say, problems can only be avoided when the owner of the vehicle means will be able to select the equipment correctly - then it will not cause any harm to the engine. Consequently, the owner will be able to save significantly.
Basic tools for setting up 4th generation HBO. Peculiarities
In addition to installing the unit, it is necessary to configure it, since setting up the 4th generation gas equipment plays an important role. If you want to know how to connect a 4th generation HBO with your own hands, how to adjust a 4th generation HBO yourself, you need to carefully study the intricacies of this issue.
To set up the equipment, you will need some parts:
- a program designed for this purpose;
- a special cable that will allow connection to the control unit of the unit;
- diagnostic cable.
How to calibrate the fuel level sensor
To constantly monitor the gas level in the cylinder, an LED indication is used, which is located on the button used to switch from gasoline to gas. Sometimes malfunctions occur that distort the readings. In this case, calibration of the gas level sensor is required.
Incorrect sensor readings can be indicated by various readings on the button and directly on the gas cylinder. You can calibrate the indicator yourself. For these purposes, first of all you need to connect the ECU to the laptop and set the correct value. To correctly perform this operation, you need to know exactly the model of the sensor that is installed on your car, as well as know its operation scheme (voltage measurement or resistance measurement). After setting all the necessary values, proceed directly to calibration.
Settings options
In order for the adjustment of the 4th generation HBO to take place correctly and competently, you need to understand that you will need to choose two options, which, in fact, will allow you to do this.
- For example, it is always possible to correctly configure the LPG, having only a cable designed to adjust the unit, doing this by changing the injection time. When this option is used, older versions of programs are ideal.
- You can achieve success using a diagnostic scanner, this is done by fuel correction. Of course, if you have a diagnostic scanner or adapter at hand, you can always configure it with one program or another.
It is important to know. It should be understood that the load on the engine is not only an increase in speed, as many drivers believe. This statement is not at all true, since when accelerating in neutral gear, of course, the speed will soar to the limit, but at the same time the load is low.
Fuel level sensor calibration
Modern LPG systems monitor the presence of gas in the cylinder by lighting the LEDs on the gas/gasoline switch button, which is located in the vehicle interior. This convenient method allows the motorist to monitor the presence of gas in the cylinder without leaving the cab. But sometimes the gas level indicator displays completely incorrect values, in which case calibration of the fuel level sensor is required.
Auto calibration
When the 4th generation HBO is correctly configured, most specialists often pay increased attention to this section. In general, auto-calibration is a simple action, and the control unit in this case will remember the gasoline injection time.

Step-by-step calibration algorithm
Note! The fuel level sensor is calibrated on an empty gas cylinder. If there are fuel residues in the cylinder, calibration should not be started!
Calibration of the gas level sensor is carried out as follows:
- Apply voltage to the gas/petrol switch button. This can be done by turning on the car ignition and waiting for the button indication to light up. It is not necessary to start the car.
- Press the gas/petrol switch button and wait for the sound signal.
- Turn off the ignition for three seconds without releasing the button.
- After the button enters the programming mode (accompanied by an indication of an increase in the fuel level from the minimum value to the maximum and vice versa).
- Fill the gas cylinder full to the cut-off point.
- Turn on the ignition; you do not need to start the car.
- If calibration is successful, the indication of the increase in fuel level from the minimum to the maximum value and back should go through twice, after which it will display “full tank”. All green indicators should be lit.
If the sequential growth of the indicators on the button continues 5 times, then something went wrong and the calibration could not be completed.
If the setup process is not successful, you should understand the reasons, be sure to study the errors that are present in the electronic control unit and, after eliminating them, repeat the process of calibrating the gas sensor indicator.

Rough adjustment for load. Peculiarities
When this option is selected, it is customary to change the cells; this is done not by revolutions, but solely by injection time. All that is required is to remember the fuel injection time, this is done at certain points in the movement, after which you need to switch to gas. This is how the 4th generation gas equipment is configured, the nozzles are adjusted and the work in general occurs. In addition, the 4th generation HBO, namely the pressure adjustment of the reducer, plays an equally important role.
It is important to know! As for the working pressure after the auto-calibration procedure, it will be automatically set, and at the level at which the adjustment is carried out. Regarding the minimum pressure, this is the gas pressure below which the system will automatically switch the vehicle to gasoline.
Attention: Every driver must understand that adjustment of the LPG gearbox, as a rule, is required only at the time of installation of the unit. But after one hundred thousand kilometers, it is necessary to perform diagnostics. It is also possible to service 4th generation gas equipment with your own hands, but only if you have the appropriate experience, knowledge, and equipment that allows you to do this.
If you consult with specialists, you can find out how to remove 4th generation HBO with your own hands, doing it at home. You always need to know that the proper operation of the unit does not depend on the quality of the electronic settings, as for some reason most car owners believe. Indeed, after a certain period of operation, valves and membranes begin to wear out, resulting in excessive gas consumption.
But this unpleasant moment can be delayed if you learn about the intricacies of proper operation of the equipment. For example, as for starting the engine, this should always happen exclusively on the car’s native fuel, which is often forgotten. Only at the moment when the engine temperature reaches thirty degrees can you switch to gas.
This is explained by the fact that the gearbox membrane freezes in practice at low temperatures. Therefore, the gearbox must be connected to the antifreeze lines, and only this way. If you want to configure the 4th generation LPG gearbox yourself, you need to realize in advance that this is not as easy to do as it seems.
Before doing such work, do not forget to warm up the engine, after which you can turn off the gasoline supply. If there is a need to adjust the sensitivity of the gearbox, then you need to unscrew the sensitivity regulator, and the procedure is performed at the moment until the idle speed values change.

Next you need to tighten the regulator and check the setting. All you need to do is press the accelerator pedal - the engine should not react to such an action, and accordingly, you should notice the absence of delays and jerks. Of course, if you managed to configure the 4th generation LPG yourself, and you did everything correctly, then the internal combustion engine will work stably and accurately.
Adjustment
- Adjusting Valtek gas injectors begins with unscrewing the adjusting jets from them. This can be done using a 12 key.
- Next, install the extension rod and secure the dial indicator to the ramp using the adapter sleeve.
- Check that the extension rod is touching the gas injector rod. If the arrow of the device begins to move, it means that contact has been achieved.
- Set “0” on the indicator device. Apply power to the controlled part for up to 1 second .
Do not apply power for more than 1 second, this may lead to failure of the part that is being adjusted!
- Write down the value obtained on the dial indicator as a result of the measurement.
- Do the above for all engine gas nozzles, recording the values.
- Next, using an internal hexagon screw located at the end of the electric coil, we set the required stroke of the rods. By rotating clockwise, we reduce the stroke of the rod, and vice versa, if we rotate counterclockwise, we increase the stroke. We set the same stroke of the rods, but not more than 0.7 mm, according to the recommendations of Valtek.
Below is a table for adjusting the armature stroke depending on engine power.
- After adjusting all gas injectors, measurements must be repeated. And, if necessary, adjust to obtain the same stroke for all injectors.
After obtaining the desired result, screw the jets back in and install the assembled ramp back into the car. We connect all the lines, open the flow valve on the cylinder, wash the system and turn on the ignition. When gas leaks are detected, we fix them without fail.

“Playing” with the supply of gasoline
The fourth generation of LPG is very “cunning” and has interesting algorithms for adding gasoline built into it. Thus, at the same time gas
and
gasoline
.
As you know, a car on gas does not behave as dynamically as on gasoline. Lovato engineers understood this problem well and created a gasoline injection mode
during sudden accelerations. As a result, we get an increase in the rate of gas combustion due to the presence of gasoline and, consequently, an increase in power. There are practically no differences in power between gasoline and gas-gasoline. On large flat areas, when there is no need to accelerate quickly, only gas is supplied. Mainly urban mode and additional injection of gasoline will not create good savings, and if you do not need the car to be as “quick” as on gasoline, then the addition of gasoline can be turned off, this is done in the Lovato Easy Fast program in the “Configuration” menu, on the “Map” tab, with the sensitivity slider.
You can also adjust the addition of gasoline in difficult conditions
, for example, at certain high speeds or help the gas injectors when they are fully open. This assistance is possible when the petrol injector time does not exceed 16 ms. Lovato Easy Fast program in the “Configuration” menu, on the “Switching” tab, “Idling” and “High speed operation” items.
