The need to twist the odometer readings may occur due to different reasons, in particular, when it comes to Gazelle cars. The principle of operation, malfunctions, as well as the question of how the Gazelle is wound up, will be discussed in the article.
[ Hide ]
The principle of operation of the speedometer
Before we tell you how to twist or wind the odometer readings, let's figure out what the principle of the speedometer on the Gazelle is. The principle of operation of the mechanism is to measure the speed of movement vehicle by means of a mechanical connection of its arrow with the output pulley of the gearbox. The latter receives wheel drive.
The shaft can give a true measure of the speed of the ride, more accurate readings will give the wheels of the car. This is because the gear pulley is located farther from the gearbox and closer to the wheels, and the speed at which it rotates is set in accordance with the final speed after the gearbox. The pulley speed may be identical in both first and fourth gear, but the difference in machine speed can be enormous.
In a transmission, the output pulley contains a gear that rotates with the pulley. The gear is connected to the speedometer drive cable. In the circuit, the cable is a strong wire located inside a protective rubberized casing. One end of the cable is installed in a special hole and fixed on the drive gear. When the gear rotates, the cable rotates with it.
The other end of the cable is connected to the device on the control panel. At the end is a magnet in the form of a shaft, which is mounted close to the steel drum, but not in contact with it. The drum is fixed on the needle and transmits the readings to the appropriate scale. When the vehicle is stationary, the needle from the cable is kept at zero level by a small coil spring.
Scheme for the manufacture of twists Possible device malfunctions
Why is the speedometer not working?
There are many reasons, let's look at the main ones:
- The device does not work. The problem lies in unscrewing the nuts that connect the flexible pulley to the device and transmission, if so, then they just need to be tightened. A broken device may be the result of a broken cable, if so, then it will have to be replaced. In some cases, in Gazelle, the device roller jams, then there is nothing left but to replace the entire device.
- The arrow on the scale began to fluctuate, extraneous sounds may appear. Initially install the shaft of the device, while the radius of bending of the cable must be at least 1.5 cm. If there is no grease on the cable, it must be added. If there is dirt at the cable installation site on the transmission, this may cause the needle to oscillate, so the dirt should be removed.
- Adjustment of the arrow of the device is broken is another type of error. If the cable is installed incorrectly in the shell of the flexible shaft, it must be mounted there again. Please note that the thrust sleeve in must be located on the side of the transmission.
- The arrow of the device rested on the limiter and does not rise higher, this may be due to a broken coil spring, the only option will be a complete replacement.
Winding up the device
So how to twist the speedometer on the Gazelle yourself? You can rewind and rewind readings according to several schemes, we will consider each of them separately.
Homemade ways
If you don't know how, then you can use simple method, which consists in interfering with the operation of the odometer. Before winding the odometer, prepare an awl with tweezers. Needs to be dismantled dashboard and partially disassemble it by opening the glass and dismantling the odometer. With the help of an awl and tweezers, the mileage in the car is twisted. The rolled odometer is installed in place in the control panel and the tidy is connected to onboard network.
There is another way, which is referred to as "collective farm". How to wind up readings in this way? Very easy - the winding scheme involves disconnecting the cable from the device and connecting a construction drill with a reverse function through it. The drill turns on and the readings are rewound, everything is simple here.
Ready options
If you are the owner of a new model, then a ready-made Gazelle Business speedometer twister equipped with electronic odometer. How to wind a speedometer with such a device? There is nothing difficult in this.
Before winding up the indicators, you need to find the OBD-2 connector on the car to which you need to connect the twist:
- First, connect the device to the connector, the ignition must be turned off.
- After activating the required mode, turn on the ignition, the indicator light should light up on the knob, thanks to which you can adjust the speed of winding the readings. If the speed is low or absent, you need to use submodes.
- After the rewinding work is completed, the speedometer made can be left, to do this, turn off the ignition and disconnect the twist. The nuances of operating the device may differ depending on the manufacturer and device, so follow the instructions when using it.
Speedometer readings are often one of the criteria by which the quality and timing of car maintenance are evaluated. More precisely, this refers to the odometer, which is integral part a device that measures the distance travelled. In order not to violate the generally accepted name of the device, it will continue to be called that way. Often, for a number of reasons, sometimes subjective, it is necessary to rewind the speedometer, changing the path traveled by the car.
About types of speedometers
Before you figure out how you can change the readings of such a device with your own hands, you need to consider its possible options. There are several fundamentally different types of speedometers:
- mechanical;
- electromechanical;
- electronic.
mechanical speedometer
Gearbox revolutions are transmitted by cable directly to the device. There, the number of revolutions is measured and converted into the distance traveled. To do this, a gearbox with a pre-selected conversion factor is used. How this is done, the photo will help to understand.
In fact, it turns out that one revolution at the output of the gearbox corresponds to a certain number of meters of the distance traveled. This rotation of the output shaft is perceived by special discs (display device) with printed numbers showing the measured distance.
Electromechanical speedometer
This type of device is further development the previously described device. In many cases, the cable has been the source of the increased error and has been replaced. The speed sensor installed at the checkpoint was introduced into the device. Impulses from it came to a motor with appropriate control, rotating the gearbox. Otherwise, the operation of such a speedometer was no different from a mechanical one, resembling it in appearance.
Electronic speedometer
This type is installed on modern cars. IN this case the number of revolutions of the wheel is measured. Knowing the length of its circumference, it is easy to translate the number of revolutions into the distance traveled. The result is displayed on the LCD. 
Why change the speedometer readings?
As already noted, drivers sometimes have to change the speedometer. In this case, the mileage is made both less and more. And if in the first case everything is clear - a decrease in the distance traveled when selling a car increases its price, then a few explanations need to be made about the second.
Winding up the speedometer is possible for several reasons, for example:
- To increase fuel costs. More mileage allows you to write off more fuel. And this is not necessarily due to fraud and postscripts. The point is that the old worn out car, fuel consumption sometimes exceeds the established norms. This is how you make up for the increased costs.
- When replacing the engine or instrument panel. In this case, it is necessary to bring the speedometer readings in line with the new conditions.
- When using discs other than those recommended by the manufacturer. Their diameter can be either larger or smaller than that specified for a standard wheel, respectively, when calculating the distance traveled, a constant error will occur. Here is the winding of the speedometer and allows you to eliminate it, including the one made by yourself.
How is the speedometer winding done?
This is a rather complex and ambiguous question. It all depends on the type of speedometer (each can use its own methodology), as well as on the date of manufacture of the car. Some possible approaches to accomplish this task will be considered below.
How to rewind a mechanical speedometer?
Similar devices are found on old cars, for example, the VAZ or UAZ families of early years of production. In this case, you can act in several ways. The simplest thing is to disconnect the cable from the speed sensor, connect a drill to it, and put it into reverse mode, change the readings. Another approach is to disassemble the instrument panel, remove the counter, and using the right tools, change his readings.
This work can be done by hand. However, this is available only on machines of older years of production (before 2005), and it does not have special significance its brand is VAZ, KAMAZ, UAZ, MAZ or Gazelle. The type of speedometer will be decisive.
How to correct an electromechanical speedometer
Despite the fact that these types of devices remained only on older machines, working with them is much more difficult than with purely mechanical ones. Here, as in other situations considered below, it is necessary to separate two tasks:
- winding the speedometer ̶ increasing its readings;
- twisting the speedometer ̶ reducing the readings of the device.
In principle, both of them can be done by hand, only the approach in each of the cases under consideration should be different. Reduction of readings is possible only when disassembling the panel, removing the counter and manually rearranging its values. But the task - how to wind up a speedometer of this type, is solved using a generator. It generates pulses that arrive at the control input, and according to their number, the readings of the device change. As in the previous case, this also does not depend on the brand of the car - VAZ, KAMAZ, UAZ, MAZ or Gazelle.
How to rewind an electronic speedometer
Similar devices are installed in modern machines and are often an integral part of other electronic systems on board. Specific methods for adjusting the speedometer readings are determined primarily by the period of manufacture of the car. The fact is that an electronic speedometer can be implemented in different ways and interact with several independent devices.
Therefore, to change its readings, it may be necessary not only to supply additional pulses from speed sensors, but also to reprogram some blocks. And besides, again, depending on the characteristics of the car, for different models UAZ, VAZ, Gazelle, etc., as well as the year of manufacture, the method of access to the speedometer will be determined.
Therefore, it is rather difficult to do such work with your own hands, although no one says that this is impossible. That's just for this you need the use of special electronic devices.
What devices are used to wind up electronic speedometers?
Considering the existing variety of machines and methods for processing data from the speedometer, several various options, allowing you to correct the indications of the distance traveled. The circuit of such a device can be made both on discrete elements and on microprocessor systems, but all finished products are divided into the following types:
CAN twist
This device is designed for use on modern machines. Here you need to know that CAN is a special bus through which data is exchanged between the electronics of the car. And its scheme implies the presence of a diagnostic connector through which, knowing the exchange protocol, you can access individual devices. 
Accordingly, thanks to this, it is possible to adjust the content of the desired memory cells, achieving the desired result. It is impossible to detect by diagnostic equipment that a change in memory cells has occurred.
You can buy a quality twister on the website https://can-podmotka.ru
Pulse twist to OBDII
This device is intended for use with foreign cars that do not have a CAN bus. This device is connected via a special diagnostic connector OBDII. In this case, the speedometer receives a sequence of pulses that imitate signals from the speed sensor, as a result of which the readings of the distance traveled change.
Speed generator
This circuit simulates a speed sensor. Instead, the generator turns on and produces a sequence of pulses that enter the speedometer and cause a change in its readings. More suitable for electromechanical devices and domestic cars- VAZ, UAZ and others produced before 2006.
Suitable for cars equipped with ABS. Its work is based on controlling the speed of movement and rotation of the wheel. The spinner connected to the corresponding connector imitates the operation of the wheels, and the controller, receiving this information, begins to change the speedometer readings.
In addition, it is worth noting that the model of the car and the date of its release are decisive when choosing a device for winding the speedometer. In some cases, changes in the speedometer readings on a VAZ or UAZ will take place in a completely different way than on KAMAZ or MAZ.
You can make a winding device yourself or buy it ready-made, but the most important thing is to determine whether it can be used on this machine. When misapplication you can just burn the electronics.
Strange as it may seem, but sometimes it is not the twisting of the speedometer that becomes more relevant, but, on the contrary, its winding. Exists whole line reasons, both objective and subjective, forcing them to do so. More than one device has been created that allows you to solve the problem, and you can choose a device that takes into account the date of manufacture of a particular car and allows you to carry out this procedure without consequences.
Sometimes, when operating a car, it becomes necessary to correct the speedometer readings upwards, saying plain language"wind testimonies". In order to do so, is currently being sold a large number of various devices according to the most different prices, and for those who are friends with a soldering iron, there are many schemes on the Internet that are proposed to be soldered by yourself.
For a ready-made "winder" they often ask for several thousand rubles, but in order to solder it yourself, you still need to purchase radio components and spend some time on assembling the device. You don't want to waste money or time? And it is not necessary! At the numerous requests of drivers in the workshop of a wandering locksmith, a special revolutionary method was developed for winding a speedometer using a conventional fan from a computer.
We will need a computer fan "cooler", which has 3 wires. Absolutely any fan with a 3-wire connection is suitable, from a power supply, from a processor, from a video card - from anything. Such a fan has a Hall effect tachometer inside, exactly the same as it is in car speed sensors.
We take such a fan, remove the connector from the speed sensor and connect the fan according to the diagram. The speed sensor in the car is on the gearbox, and in 4x4 jeeps - on transfer case. We remove the connector and connect the fan instead of the speed sensor, turn on the ignition and let's go! The fan should start spinning, and the speedometer should wind up kilometers. The purpose of the pins of the speed sensors of most cars is shown in the diagram, do not forget that the "mothers" of the connectors are mirrored, to ensure correct connection, check the "plus" and "ground" contacts with a tester, when the ignition is on, they should be + 12 volts.
Do you have everything sealed and the connector can not be removed? Don't worry, we've thought about that too! Extend the power wires from the fan so that they are enough to the battery and connect the fan to the battery directly. Attach a needle to the signal wire of the fan and, in an inconspicuous place, carefully pierce the insulation of the signal wire from the speed sensor, connect the fan signal in parallel. But with this method of winding, you will have to tinker a little. The fact is that the outputs of the sensors are made according to the "open collector" scheme, and if the magnets in the standard sensor are in the position when the output key of the speed sensor is open, then the winder will not be able to work. What to do? It is necessary to catch the moment when the key of the standard speed sensor closes, and only then start the winder. How to do it? The surest option is to jack up rear wheel and gently turning it to catch the moment when the winder starts to work, but you can try and push the machine a little bit, although this can be difficult. Do not forget that in any case, the ignition must be turned on in order to start the speedometer itself.
Please note that different fans have different speed rotation, the speed of the fan is written on the sticker, of course, the faster the fan, the faster you can wind the desired readings, but meanwhile, in some speedometers, protection against too impatient, and too high speed winding the speedometer stops reading. What to do in this case? Just find a slower fan.
Where can I get the right fan? Yes anywhere, pick out faulty computer, ask a friend, find it in a garbage dump, buy it in a store. There are coolers in any computer store, the price for them starts from 100 rubles, and finding a fan is much easier and cheaper than buying or soldering a winder.
And that's... Don't steal too much, okay? :)
CAN spinner and speed generator: is there a difference between these devices?
The difference between the devices lies primarily in the vehicles they are compatible with. The CAN twist can only be used on cars equipped with a special CAN bus, mainly foreign cars older than 2006. The winding generator, in turn, is compatible with older foreign cars, as well as with Russian-made cars.
Are there any rules in the traffic rules or the Code of Administrative Offenses prohibiting the procedure for adjusting the odometer?
No, there are no such prohibitions in the paragraphs of the rules, as well as in the Code of Administrative Offenses, with the exception of such a moment that changing the mileage readings should not violate the rights of third parties. Otherwise, the owner of the vehicle is free to decide what mileage will be displayed on the dashboard of his car.
I live in Irkutsk. How long will it take to receive the device and how can I pay for the order?
We ship speedometer readings by mail to any settlements of the Russian Federation on the same day when the order was made. You can pay for the purchase directly at the time of its receipt. As for the duration of delivery, it all depends on the location of your locality and mail speed. For example, the package will be delivered to Irkutsk within 5-7 days. At any time you can get information about the status of your order by tracking it on identification number, which we send you via SMS after sending the device.
How to connect the device to the car?
The connection procedure is very simple: the winder is connected via the CAN bus through the diagnostic connector, most often located under the steering column or next to it. When connecting the generator, interference with the electrical wiring is NOT PROVIDED!
How can you determine that the speedometer has already been artificially changed?
If this procedure was carried out using one of our devices - then no way. Moreover, it will not be possible to do this either at the MOT or at the service center.
How much is delivery within the city?
In Moscow, delivery of the winding generator is free!
How quickly can you deliver the device to me? I live in the VDNH area.
We will be able to deliver the device to this area of Moscow within an hour, but in general, delivery around the city almost never takes more than 2 hours. We can deliver the order to the destination at any time convenient for you.
Does the device exert a large load on the battery when the ignition is on?
Our run winders consume a minimum of energy. The consumption of electricity from their work is comparable to the consumption required to charge a mobile phone.
I want to learn in detail about all the possibilities of the speedometer twist. Who can explain them to me clearly?
A specialist from the Avtopribor company will tell you about all the features of the operation of the mileage winding generators, Special attention will be given a story about how to use the device. If necessary, our staff will answer any of your questions.
Will the speedometer corrector or the procedure for changing the mileage indications work electronic system my car?
All our devices are certified and absolutely safe. Before entering the market, they are tested for performance and safety at special equipment. Our winders will not cause any harm to your car!
What is the warranty period for mileage correctors?
All devices are guaranteed for 5 years.
Is the diagnostic connector and CAN bus the same thing or not? If not, please explain what is the difference?
This is not the same thing: the CAN bus is a device that makes it possible to combine and use all the variety of functions, properties and capabilities of various electronic devices, and the diagnostic connector is the place to which the diagnostic tool is connected. service equipment, and in our case - a twist of the speedometer readings.
Do you offer discounts for the purchase of spinners?
Yes, sure. And you can get the first discount by ordering 2 or more devices from us. With all subsequent purchases in our company, the discount will increase.
At what speed will the device wind up the mileage?
The winding speed depends on specific brand and car models, the range here is very wide: from 200 to 7000 km / h. You can find out the exact winding speed for your machine by calling us.
The winder is broken! What to do?
You can exchange a damaged device for a new one by visiting our office in Moscow. If you live in another city, you need to send us a broken device by mail along with the 14-digit code indicated on the receipt. After that, we will send you free new device to replace the damaged one.
Changed the car. Will the old speedometer knob be suitable for changing the mileage on it?
In most cases it won't work. However, with us you can exchange old appliance for a new one with a small surcharge.
Working with speedometer rewind
Speedometer knob intended For independent increase in mileage by car in a big way. Winding up the speedometer no way can not reduce the mileage of the car!
The winding of the speedometer is connected to the diagnostic connector of the OBD2 car. According to the international standard, the diagnostic connector is located in the passenger compartment within a radius of 90 cm from the steering wheel. Most often, the connector to which we will connect speedometer knob, located directly under the steering column, sometimes in the glove box (Reault Logan, Duster, Lada Priora). The connector can also be hidden. plastic parts salon.
If you cannot find the connector in your car, use the search on the Internet, or contact our manager for help..
More often no modifications to the wiring are required for the operation of the speedometer knob, i.e. car and speedometer winder immediately ready to go. BUT in some cases, for example, on cars of the brands VW, SKODA, MERCEDES, TOYOTA RAV4 from 2016, Toyota LC200 from 2016, some Mitsubishi , V diagnostic socket the car does not have the wires necessary for the winding of the speedometer(namely high-speed motor tire CAN, which spinner sends digital messages). In this case, you will have to do the revision yourself or with the help of an auto electrician. We always inform about the need for improvement before buying / sending the device !!! If you were not told about the need for revision, there is no revision instruction and additional wires in the kit, then this is not required in your car. If revision is necessary, follow the instructions, and in case of difficulty, contact the manager. Question about connecting speedometer winder you can ask in the chat on the site site, as well as by phone 89206843692.
To start winding the speedometer on a car, you must turn on the ignition and insert device for winding the speedometer into the diagnostic socket car (or first insert speedometer winder in connector, then turn on the ignition, the sequence does not matter). End LED spinners should start blinking once a second. If the LED is off and there is no change in mileage, then this indicates that there is no 12V power in the diagnostic connector of your car. Check fuses. If the LED is on continuously, it means winding up does not see digital bus car, contact the manager for technical advice.
On Peugeot cars boxer, Citroen Jumper, Fiat Ducato to start winding the speedometer you need to start the engine. It is also allowed to start the engine on other cars (on Ford car Focus 2 winding with the engine running leads to an unpleasant blinking of some control lights on the instrument panel, for peace of mind, do not start, although there is nothing really wrong with that).
After winding speedometer to the desired value, disable speedometer winder and turn off the ignition (again, in any order).
Long car downtime Not damages car electronics. If you are planning a long winding, turn off unnecessary consumers ( air conditioner, side/running lights) to avoid discharging the vehicle.
The use of the speedometer knob while the car is moving is not prohibited, but it is not recommended either. the operation of the winder is based on imitation of digital messages from the ABS unit (or from the ECU), and it is not known how brake system behave in difficult road conditions. Also, on cars with electric power steering, there is a decrease in effort (the steering wheel turns hard even on low speed, because amplifier thinks you are going fast). Some drivers in cases with a large mileage lag use winding during movement. But you must understand that you are doing this at your own peril and risk!
