The Lada Granta is equipped with a standard BC built into the instrument panel, but its functionality is frankly weak, and therefore does not suit the owners. Car enthusiasts consider the main disadvantage to be the lack of an engine temperature sensor. That is why many people prefer to install alternative on-board computers that are capable of demonstrating current temperature readings and many other parameters of the operation of all car systems.
Basic functions of the device
On-board vehicles for the Lada Granta have high information memory and a small monitor, except for the “State” model, which only has a digital display. This makes it easier for people with poor eyesight and those who are unfamiliar with the nuances of engine operation to monitor all the processes that accompany its stable operation. BC will help the car owner by pointing out the following parameters:
- total travel time;
- detailed fuel consumption at different speeds;
- average speed indicators and excessive fuel consumption;
- remaining fuel in the gas tank;
- speed of start of movement;
- engine temperature;
- malfunctions of components and mechanisms;
- temperature inside and outside the car;
- on-board network voltage;
- crankshaft rotation speed (engine speed).
The on-board computer has a volatile memory and the ability to control the anti-theft system - the Lada Granta immobilizer. The on-board vehicle has a built-in supervisor, a fault indicator, and a “afterburner” function - the ability to reset the memory after starting the engine.
The functionality of even the simplest on-board computer is much broader than the standard one installed on the Grant. The discrepancy between the readings of the factory and alternative devices can reach more than 30%.
Some on-board drivers can additionally control lighting, stove operation, clock, calendar and alarm clock, and automatic window closers. You can plan your trip route based on the BC readings. It also allows you to use various navigation installation options and can warn you about low fuel levels or exceeding the permissible speed limit.
Most devices allow you to independently diagnose the operation of different car systems. The device can read ECU error codes without using any equipment. The explanation is presented in the accompanying documentation for each device. Such functionality will allow you not only to save on a trip to a specialized center, but also to identify problems, preventing serious malfunctions from occurring.
Choosing an on-board computer for the Lada Granta
As an alternative to the weak standard BC, car enthusiasts install multifunctional on-board monitors that will show not only the engine temperature, but also many other parameters. Today, manufacturers can offer three main devices suitable for the VAZ 2190-91: “Multitronics”, “Orion”, “State”.
"Multitronics"
The device is a universal one, since the manufacturer does not produce them exclusively for Grants. Judging by the documentation and instructions included with the device, installation of Multitronics is quite possible on earlier VAZ cars: first-generation Kalina and Priora. Finding a place to install the device is the concern of the car owner.
"Orion"
The computer of this brand is also universal and is used not only for Grants. The installation site may have to be modified independently.
"State"
This company produces on-board computers exclusively for domestically produced cars. The devices are not created for universal use, but specifically for each car model.
"Stat" is based in Togliatti and tests all its developments on AvtoVAZ cars. Installed instead of a plug for additional buttons. This device is modest in size, but has additional useful functions:
- spark plug warm-up mode – relevant in winter;
- “Tropic” mode, which allows you to independently set the desired temperature for the engine cooling fan to operate;
- diagnostics of system errors.
The “State” X1 M is inexpensive, which makes it noticeably superior to its competitors. But if you need a full-fledged on-board computer with a display and an intuitive interface, you should take a closer look at universal devices.
Installing a BC can pay for itself after the first replacement of a sensor, because the car owner will be able to carry out diagnostics on his own.
Versatile alternative
Of course, thanks to their various mounting locations, Multitronics on-board routers can compete with the States. Powered by a 32-bit processor, multitronics are precise and fast in operation. If a car enthusiast has the opportunity to buy such an on-board computer, then the car will be under excellent control thanks to functions such as:
- a large number of diagnostic protocols, including extended ones;
- transfer and save all driving statistics to a personal computer;
- voice accompaniment;
- parking radars, etc.
All of the above functions of the State on-board vehicle have been added to the multitronics. In addition, the latter have easy setup for operation and a convenient user interface. But due to all this, the price will be much higher than that of a compact and more suitable State Grant.
Initially, it was possible to buy on-board computers for the Lada Granta only from the official one. Since sales of this car started at the end of 2011, for some time the unavailability of additional equipment for the Lada made it not very popular among car enthusiasts. However, it is now possible to buy on-board computers for Grants from official dealers and various suppliers of automotive products and equipment.
Options for installing BC in Lada Granta
Any of the existing onboard devices can be installed and connected independently, regardless of the modification of the car. The exception is computer models in the “Lux” configuration - they are initially installed at the factory with a multimedia system, navigator, and audio system. The “State” X1 M device can be added to the “Standard” and “Norma” configurations.
An important advantage of the “State” X1 M is its compact size. The device is installed instead of a button cover. The kit includes the device, wires and instructions. Installation will not cause much difficulty. You need to take out the plug, place the computer in it, connecting it to the connector. Then, in accordance with the pinout, connect the second end of the wiring with the block to the diagnostic connector located on the bottom left side of the panel. In addition to the State X1 M, Multitronics are often installed on Lada Granta. You can attach it wherever it is convenient for the driver - on the dashboard, on the rearview mirror. The main difficulty is connecting the wiring, since it needs to be hidden. If you install the device on a panel, you will first have to remove its front side and make a hole for the wires, for example, using a heated knife. Then the BC visor is glued to “liquid nails” type glue.
This completes the installation, all that remains is to connect the on-board vehicle to the diagnostic block and wait for it to initiate with the electronic control unit of the Lada Granta. If the device doesn’t show anything other than the voltage of the on-board network, that is, it didn’t work out to make friends between the brains and the computer, then the reason is inappropriate software.
On-board computer firmware Grants
You can update the software yourself. To do this, you will need a USB-K-Line cable, the firmware itself, a diagram of the Lada Granta ECU, an installation program and a driver for connecting to the adapter.
BC connection diagram for firmware
Schema collection algorithm:
- Take 3 wires.
- Switch T1 is closed as required by the program.
- The computer serves as the power source; just connect to Molex. For the on-board device, you can use the terminal block from the cooler.
- Connect the adapter to the USB port and install the driver. Next, you need to remember the port number you are using.
The firmware process looks like this:
- The program starts and the firmware is selected.
- The desired port is selected.
- Click on the lightning icon, after the “Turn on power” message appears, you need to press any button and start the firmware protocol, this will take several minutes.
To download all the software necessary for flashing the firmware, just go to the official website of the manufacturer of the Lada Granta on-board computer. You can also find all the necessary drivers there.
