On-board computer - a small automobile device that reads, processing, as well as output to the display of useful information.

Why do you need an on-board computer

Currently, the on-board computer is definitely an important element of the car. It shows fuel consumption, its residue in the tank, time in the way, the oil level, the electrolyte level in the battery, the exact speed mode, the presence of problems with lamps, toxol and much more. On-board computer controls all the technical characteristics of your car. When the slightest failures occur, the computer will notify the owner of the vehicle and if possible, liquidates the problem.

Most popular firms for the production of onboard computers

• Multitronics.. Moscow enterprise, which issues not only onboard computers, and also diagnostic equipment. There is already a production for thirty years, there is a well-established service and dealer network. The buyer has the opportunity to use after-sales support for free.
• NPP "Orion SPb". The enterprise without restrictions produces onboard computers on the vehicle brand. You always have the opportunity to choose the desired model on the manufacturer's website according to the compatibility directory.
• STATE LLC. The company from Togliatti launches onboard computers for cars "GM AvtoVAZ". There is permission for mounting for warranty cars. There are also universal models.
• Microline.. The company offers buyers a series of side computers "Prestige". Preferably, use on domestic cars, however, there are models of universal type. There are support for the main protocols.

What to pay attention to when buying an on-board computer

There are two options for onboard computers - universal and model. Universal devices are suitable for any car, model - only for a specific vehicle model. Universal variations are much faster installed, but devices with the most advanced characteristics are manufactured for specific models of cars.

When choosing a BC, you need to know which type of electronic control unit in the engine. There are three types of control units: January, Mikas, Bosch. Also, when choosing a computer for a car, pay attention to the presence of a malfunction definition function in the operation of certain velocity of the car.

Field Computer Installation Places

Installation of the BC can be performed in several most convenient sectors:

1. Place block of control lamps.
2. Regular place BC.
3. ISO seat.
4. Windshield.
5. Dashboard.
6. 2 DIN or 1 DIN-car seat.

How to install on-board computer with your own hands, step by step

First you need to decide which place you will install the BC. In this case, we chose the space near the rearview mirror. The BC will not interfere with the BC.

1 step.No  it makes sense to apply bilateral scotch, as traces remain from it. Therefore, you need to do four holes with a thin drill. They must be done on the stand performing the role of fastening on the windshield. With the help of plastic clamps, you need to attach a stand to the mini-gluke grid, which is located on the ceiling of the cabin. Do it extremely carefully. Connect the cable with data to the connectors. Do not forget about the signaling wires parking sensors.

2 step.Confirm the device to the holder, and flat loops with information hide in a small corrugation. Move the trim from the glass to a couple of millimeters, after which I wake there loops. We dismantle the rack's trim using a flat screwdriver. Then turn off the chip at the bottom.

3 step.Stretching the loops under the trim, can put it in place. In fact, the installation of parking sensors is actually completed. Everything will function except fuel level indicators. Therefore, it is necessary to continue. You must open the glove box, deduct the stroke limiters and pull them out. Next, remove the chip that is on the clip.

4 step.I pull out the "brains" of the b and E chips from the brain. Next you need to perform the most difficult: blue, red, brown and yellow cables on Fishke B control the operation of the nozzles. You can connect to one of them, but it is desirable to choose brown, which is located closest to you. Now remove some insulation from the chip cable. Connect the wiring from the side of the onboard computer (it is blue), which is responsible for connecting to the nozzle. Next, isolate the connection. Working with the china is not so difficult and laborious. Connect to a blue wire with a white strip wiring from a side computer pads (has a purple color). Now I set the limiters in your place.

5 step.It has arrived at the instrument panel. Gently dismantle it (it is often fixed using latches). Pay attention to the right chip, here you will see the yellow-black wiring, which is responsible for demonstrating the fuel level. Connect the green cable from the BC pad to it. Then carefully put the instrument panel into place. Now it remains only to connect the air temperature sensor on the street. This is done as desired, since the main components have already been connected.

Gently laid all the wires. It is advisable to clean the beams of the wires using the isol or clamps. Connecting the battery, run the motor. Then wait a bit, since the on-board computer will be engaged in the auto definition of the protocol. Now you need to hold specific settings that are specified in the instructions.

How to reflash the on-board computer

Most often, as a result of the diagnosis of the on-board computer, or the vehicle itself can be noted that to optimize those. The characteristics of the car can only be riveted in the BC settings using the ECU. So you can increase the power of the vehicle, without disassembling its motor. To do this, you need to know how to reflash the car's BC with your own hands. As a result, you will receive a more active and dynamic car.

Qualitatively completed flashing guarantees you the following results:

1. Smoker motor operation.
2. Increase maximum speed.
3. No shifting jerks, gearbox operation becomes smooth.
4. Fuel consumption becomes smaller.
5. The power of the power unit will pleasantly surprise the motorist.
6. The increase in torque value is about 15 percent.

However, these are only secondary improvements that will occur after the firmware, the main "highlight" of this action is the management of management. However, this is possible only if the procedure was correctly executed.

Tips Prof.

Finally, I would like to say that you should not try to save when buying a BC, since cheap devices are not distinguished by special accuracy of readings.
