Function by function details
Fifth generation mode also known as 5th, or positive pressure (blue or white)
The blue or white switch has the possibility of being used in teams of 5th and 6th generation.
In this mode who administers the fuels is a CNG system computer.
For that same reason in 5th mode, the switch only works as a measurement center, to be able to read the actual pressure of the cylinder, the voltmeter, and the lambdometer.
The latter is essential to be able to diagnose a correct configuration of the CNG equipment.
Change when the GAS runs out
When less than 10 bars are left, it is automatically passed to naphtha, and the digits begin to flash. Works on carburetor or injection vehicles. It can be disabled if you do not want to use it. It is factory disabled and must be enabled after calibration
Injector protection (red and blue models)
The biggest problem of injector clogging is due to the very little use of naphtha. Being that it stagnates and rots in the tank.
What we call injectors protection, is a time programmable by the user, that every time you turn on the car it will work with naphtha and only with naphtha. After said time the change will be made in the first accelerated motor (as always).
For example: Turn on the car (in automatic mode) and you will see that between the first 20 seconds and 4 minutes (according to what you program) the AU legend will note that in spite of accelerating the car continues to run on naphtha during that time. When the digits stopped flashing the system is waiting for its first accelerated to switch to gas
Advantage? Lengthen the life of the engine and prevent one of the main problems in the injection.
Voltage meter (red and blue models)
Useful tool that allows you to monitor that the battery charge
It can thus detect a fault in the alternator or the battery.
With the engine running, the normal is between: 13.5v and 14.2v (never again)
With the engine stopped the normal is between: 11.5v and 12.6v (depending on the time stopped)
Lambdometro (blue model)
The lambda probe is the sensor used by the injection computer to establish that the gas / air mixture is correct.
Circulating with gas, the probe CONTINUES TO WORK only that it is generally ignored. 90% of cars have probes from 0V to 1V and a correct mix would be the closest to 0.5V
Although it is impossible to fix this value (it is not achieved even by the ECU operating on naphtha) it is possible to see its behavior.
If it always marks less than 0.2v it means that it is supplying little gas and endangering the engine. If you always mark more than 0.8v it means that you are supplying a lot of gas
Therefore, good regulation is always considered if it oscillates between rich and poor
Piston melted by poor mixture (capped naphtha injector)
Piston punctured by very rich mixture with exessive advance
Valve burned by poor mixture
Help in passing gas to carbonated gasoline
When the GAS pass is made to NAFTA, the switch injects EXTRA GAS so that NAFTA reaches the carburetor.
It can be disabled if you do not want to use it.
Change in deceleration
This function is available ONLY for injection vehicles.
In automatic mode (normal mode) the vehicle is ALWAYS switched on at naphtha and then automatically switches to gas when the engine is accelerated.
When the first gear starts, it does naphtha, but when you press the clutch to put the second one, the change is made automatically. And already the second gear is on gas, without you realizing that it has changed fuel.
Running on gas until you turn off the engine. It can be disabled if you do not want to use it.
Control for pump cut relay
This function allows to connect a relay on the green wire (naphtha valve) and thus activate a smart pump cut
In addition this function is preparatory for future functions
Adjustable priming time
As always attentive to the suggestions of our clients. We received the news that the priming time was very long, and sometimes the car was drowned when it started.
Now it is completely configurable between 0.5 seconds and 6 seconds approximately
Brightness control
Because there are vehicles that carry the selector close to sunlight.
And other vehicles have very polarized glasses, you can adjust the brightness of the screen in 15 different levels for the one that suits your needs
The higher the number the greater the attenuation, the digits will have.
3 buttons
To avoid confusion and potholes play a trick each button has its function:
If you press naphtha the vehicle works with NAFTA and only naphtha
If you press gas you will use GAS, and only gas (it can only be changed to naphtha if you have enabled the function when the gas runs out)
If it is injection and press AUTO change only.
If carbureted and press OFF there are no fuels.
Clear and simple, without confusion
Dual Carburetor - injection
The same switch serves both for a carbureted car or an injection
Thanks to its microprocessor the switch knows how to behave in each case
Originally come set in injection mode so the installer must follow the instructions in the manual to change it to carbureted. IF IT DOES NOT DO IT, THE VALVE DOES NOT OPEN.
AUTOMATIC mode (injection only)
When the middle button is pressed, the switch will go into automatic mode.
This means that every time you turn on the car, NAFTA will be started.
When it accelerates to more than 2000 RPM, it will automatically switch to gas
Running on gas until you turn off the engine.
