How to twist a run on an electronic speedometer yourself

According to statistics, every car rolls about 17,000 km a year. And in the secondary market, a large number of used five-year cars with an estimated 50 000 km mileage. In such cases, potential buyers have the thought of their luck that it will be possible to purchase an iron horse with such kilometers. But in fact, half of the owners of cars, most likely, wondered about how to twist the run on the electronic speedometer. And before selling many just did.

How it works?

The meter itself is called an odometer. It is mounted in the panel of the speed meter. In the device of the electronic speedometer there are no reducers, cables, rollers, like its mechanical predecessor. Often the output shaft of the gearbox is equipped with an optical or magnetic sensor (it can rarely be mounted on the wheel), which fixes the revolutions. Then the received data are transferred to the electronic control mechanism and from there already to the display. Information about the run can be stored additionally in several memory blocks, as on the new flagships of BMW, Audi, Toyota. How can I twist the run on an electronic speedometer with backup data storage points? These models are quite complex in rewinding values, have up to 7-8 points of data storage on the passed way.

How do I set the required kilometers?

For cars belonging to the budget price category, it is enough to remove the panel of the electronic meter panel and connect to the output for diagnostics. Connect the other end of the cable to a computer with previously installed software. After that it will be possible to enter new mileage indicators. Moreover, it is very difficult to detect such interventions only if the owner has inadvertently unscrewed the panel cover and left mechanical damages. In this case, the twisting of the values is likely, but the owner can report the diagnosis or replace the lighting elements.

If there are several memory blocks, this process becomes somewhat more complicated, but not drastically. How to twist the run on the electronic speedometer in the presence of 6-8 points of backup information storage? Here you need to connect to a car computer and use special programs to work with all the blocks - you can not miss a single one. Otherwise, there is the possibility of the appearance of the previous indicators on the display. In rare cases, reinstall the ignition lock, or solder a new chip into the control unit.

How can I twist the run on the electronic speedometer myself? It will require technical support and a good knowledge of electronic systems. On specialized services this manipulation does not take much time (up to 2 hours).

Are there cars where twisting is impossible?

At the moment there are no cars that do not allow you to adjust the value of the kilometers traveled. Producers have no reason to tackle this matter closely, to spend money. The buyers do not care about used cars. Therefore, when buying, you should be careful and expect luck or an honest seller.

What is the cost of such work?

To tweak indications from representatives of the budgetary sector of motor vehicles will cost from 1000 to 1500 rubles. The speedometers of the novelties of the foreign car industry will cost 3,000-4,000 rubles. The price may depend on your knowledge and personal imagination of the master.

How to find out the winding of the kilometers?

The definition of intervention has low chances, but motorists need to know how the interior elements look at a particular run. The driver's and front passenger seats can be too worn out, the handles are worn and will have scrapes that are not comparable to the declared mileage readings. But the owners can slightly patch the salon. Covering the seats and replacing the handles - not too expensive procedure. The diagnosis itself with a computer will not work. In most cases, when servicing employees, they stick tags with the distance traveled so that vehicle owners are aware of the time of the next oil change. If there is a mismatch in the number of km on the tag and on the display, the owner will be convicted of twisting. Also, be sure to ask for a service checklist. If it does not exist, then there is a high probability of intervention.

We sorted out a little with the question of how to twist the run on the electronic speedometer, the situation became clear and the general concepts became known. When choosing a used vehicle, more attention should be given to its condition, drivers differently follow the technique.

Correction of the values of the domestic "Gazelle"

Depending on the type of occupation, motorists can move to a domestic car. A very running truck for cargo transportation is "GAZelle". On them, too, electronic systems for fixing the value of the traversed path are already installed. How to twist the run on the electronic speedometer ("GAZelle Business" diesel)? To do this, it will also be necessary to connect to the electronics system and set the required parameters using a computer with a special program. The connection is made via the diagnostic port. When paired, the program will show the current value on the screen, then you can enter the desired value. As for cheating, this can be done through a programmer.

Twist the run of the electronic speedometer VAZ2114 himself

Since 2001, several variants of combinations of electronic devices have been installed:

• Panel AP (produces Vladimir Plant "Avtopribor", equipped with a microchip PIC12C519). There have been cases of failure of this chip. The cause is a factory defect. Reinstall and flash it using the programmer software-5. The cost of making adjustments in the workshops is 1100 rubles.
• Electronic system Shetmasch. For work with her in services ask 1600 rubles.
• Electronic device type VDO. The master will ask you to pay 1500 rubles.

To do the work with your own hands, you will need knowledge of electronics and appropriate equipment (a computer with an installed program). The connection to the electronics of the car is being carried out, manipulations with the indicator of kilometers are carried out. How to twist a run on an electronic speedometer? Ryazan has a sufficient number of services and electronics to perform such operations. Also here you can get technical support if you want to do it yourself.

Here are the general concepts and algorithm of action. It is quite clear that not every technician will understand. It takes some time to learn the basics of electronics. For those who are concerned about how to twist the speedometer and the mileage of the car, actions are taken to disassemble and connect the equipment.

How to connect

Connection order:

1. Unscrew and remove the rear cover of the dashboard.
2. Ensure a reliable fastening of the connecting wires to the contact points.
3. Connect the power cord and turn it on. After that, the current value should appear.
4. Make an operation to connect the adapter to the computer's LPT connector.
5. Initiate the launch of the program.
6. Pressing the "F6" key will read the kilometer reading, "F7" - you can enter the desired value. Then you need to press "Enter" and you can close the program.
7. Carry out a power cut and collect everything back. Now when you start the car on the speedometer there will be new mileage values.

The causes of the twisting of the speedometers

The number of kilometers covered by the car is one of the main selection criteria. Therefore, the question arises as to how to twist the speedometer and why it should be done. With the first half, everything is clear. But why? All is that sellers simply want to earn more on selling. People involved in the sale of foreign cars perceive this as a profitable business. Abroad cars are doing better and the roads there are good, so you can not visually determine the high mileage. Sellers adjust its value to the buyer and help out with good money. Also, it is not uncommon for the kilometer counting system to malfunction and the incorrect display of this value. The cause of this can be interruption of power from the battery. In this case, too, you may need to change the mileage.
