“No matter how much you steal from the state, you still won’t get yours back!”
With the development of injection systems on domestic cars, there has been a steady demand for devices that “wind up” electronic odometers. Why is this necessary, you ask? The answer is obvious: for drivers of state (official) cars, this is a way to write off gasoline. And, as you know, now it has become expensive ... Previously, when there were only mechanical odometers, this problem was solved in different, also mechanical ways. Then the first electronic odometers appeared, and the "advanced electricians" of various car depots found a simple and effective way to wind odometers by stretching the wire from the additional terminal of the generator to the instrument panel. But the electronics did not stand still, and when, having once connected the magical wiring in the manner described above, the electrician discovered that the car would not start, there was nothing left to do but send the suffering driver to look for other ways to solve the problem.
And it all started with the usual Gazelles and Sables with 405 engines, of which there were enough divorced at our city-forming enterprise. It was they who began to stall when using the above method.
The fighting technique is very simple and effective. The Combiloader PAK is connected to the ECU of the experimental car and the serial engine control program is read. Further, it opens in the CTPro program and the flag of the speed sensor is removed from the configuration. And with such a small change, an already modified engine control program is written to the ECU. In principle, after that, you can call an “advanced electrician from the car depot”, who will throw a magical wiring from the generator and the process, as they say, will go ... But this is not our method.
The simplest three-piece generator is made using the bulk mounting method (see the diagram below).
Toggle switch S1 switches the signal going to the panel either from our generator or from a standard speed sensor. The generator is powered from the plus of the ignition switch. Thus, the main advantage of this solution is that you can wind up the mileage without starting the car (just turn on the ignition), as well as right on the move of the car “moving at a speed of 200 km / h” to the envy of colleagues in the fleet.
A few notes on the diagram. Of course, a fastidious electronics engineer will definitely recommend putting another resistor in series with a trimmer so that the generation does not break down in the extreme left position of its engine. And also necessarily a protective diode against reverse polarity of the circuit. But you and I do not need it, we are neat, attentive and unhurried. With the values of the resistor and capacitor indicated on the diagram, the circuit generates rectangular pulses with an amplitude of 12 volts in the frequency range from ≈ 180 Hz to ≈ 1.5 kHz, which has so far covered the need for using this device on different cars.
If you need to quickly change the range of generated frequencies, you need to replace the capacitor. When it decreases, the frequency increases and vice versa.

In conclusion, we denote an approximate algorithm for searching for one single, necessary wiring through which information about the mileage is sent to the instrument panel odometer.
1. Inspection of the gearbox, drives, rear axles in order to detect a speed sensor.
2. If the speed sensor (or something similar to it) is detected, then you need to make sure that it is it. Remove the connector from it and make a small test drive. The speedometer or odometer should stop working.
3. If the detected speed sensor is three-wire, then it is necessary to measure the voltage at its connector and determine the signal wire. Next, ring this signal wire to the instrument panel in order to connect the winder in the cabin. If the sensor is two-wire, then it is necessary to determine the shape of the signal that comes to the panel. This can be done by hanging the drive wheels and making them spin, control the signals coming to the panel with an oscilloscope.
4. If the speed sensor is not found in point 1, then it is very possible that the panel receives a speed signal from the ABS. Then, using the method described in paragraph 3, it is necessary to search for this signal with an oscilloscope, on the instrument panel connectors.
Of course, if you have detailed information materials on the car model that you are going to subject to such “tuning”, then the task is greatly simplified. But in any case, do not forget that you are acting at your own peril and risk, and therefore double-check yourself three times before thoughtlessly “strapping something to something”. I would also like to note that this brief review highlights the general principles for solving this problem, and the specific implementation on a specific car can vary greatly in the direction of complication. If you have information on connecting to other types of cars, send us, we will gladly fill up the table of "applicability"
Some notes on creating winders for Ford Mondeo & Ford Focus, 2006 release, Toyota Camry
These vehicles use signals from the ABS sensors as a speed signal. On these models, these sensors are current, which means that when the wheel rotates, the current in the circuit changes. The changes are approximately 7/14 mA, that is, if you connect the oscilloscope in parallel to the sensor until the wheel rotates, we should see a square wave of approximately 0.5 Volts against a background of 12 Volts. The circuit below simulates the complete operation of such a sensor.
The positive wire can be determined by removing the connector from the sensor and measuring the voltage on the wiring with the tester with the ignition on. We used full manual reconnection, that is, to carry out winding, the client opens the hood, removes the plugs from the connectors, and puts the winder in place of the plugs. Turns on the ignition, produces the necessary winding. After the end, he removes the winder from the connectors, and plugs the plugs into the connectors, which restore the factory connection of the ABS control unit with the sensors. Of course, it was possible to switch all this on the relay, but there were a lot of extra wires under the hood, and disguise was put at the forefront. It is imperative to use two wheels, since with one the speed does not rise above 30 km / h.
Now consider the car TOYOTA CAMRY, 2006 model year. The panel of this car is called Optitron, and has a neon backlight. Machine 3.5 liters on the machine. The speed signal is also taken from the ABS sensors, but is a sine wave with an amplitude of about 1 Volt and a frequency directly proportional to the rotation speed. That is, the ABS sensor is applied inductive type. In this case, the following scheme was applied. The transistor is applied to any type of KT3102. A resistive divider reduces the amplitude of the output signal, and a capacitor with a capacitance of 0.1 μF to 0.47 μF removes the constant component of the signal. As a result, of course, a clumsy signal was formed at the output, but the ABS control unit swallowed it perfectly and the desired result was obtained. It should also be noted that such a signal must be applied to the two front wheels. True, in this case, complex switching was not required, and the necessary signal wires were tied directly to the standard wiring.
In conclusion, I would like to remind you that ABS is one of the important systems that affect safety, and if you have already decided to intervene in it, you must clearly understand the consequences and, in accordance with this, perform work at the proper quality level.
A small addition to the "KAMAZ" odometers. This device can easily be adjusted to "incorrect" readings using
And speedometer winding GAZ, as well as other trucks or cars. Winding the speedometer is a compact device that is quite easy to use and allows you to artificially wind the mileage on a GAZ truck in a matter of minutes. The GAZ speedometer winder gives drivers the opportunity to quickly wind up the mileage and, best of all, the winding fact cannot be later diagnosed with any diagnostic device or equipment.
Often, winding up a tachograph or winding up a speedometer is necessary for drivers working in companies where fuel and lubricants are compensated from certain fuel consumption rates per kilometer. But, unfortunately, this does not always allow you to correctly calculate the real consumption and, ultimately, the driver will have to pay for part of the fuel out of his own pocket, since the fuel consumption when driving in traffic jams and congestion is much higher than the norm. It is simply useless to prove to the employer that fuel and lubricants were actually used up more than it is required by the standards. To resolve this situation, the winding of the speedometer or tachograph of GAZ cars is used.
Direct fuel injection systems on domestic cars made it possible to use fuel efficiently, while increasing engine power. Recently, there has been a great demand in the automotive market for devices that wind electronic odometers. Who benefits from winding up mileage in your car?
The answer to this question is obvious. Drivers of state, official (corporate) cars, thus, get the opportunity to write off gasoline. And today he is worth his weight in gold.
Previously, mechanical odometers were installed on old car models, and kilometers could only be measured mechanically. Over time, the electronic odometer was invented, and skilled radio electronics specialists from various car depots came up with a simple and effective way to wind the odometer. For this process, you need to connect the wire from the additional terminal of the generator to the dashboard, where the odometer itself is located.
But electronics engineers have developed new odometers that are very difficult to crack. And when once in the garage they connected the odometer in the way mentioned above, the radio technician discovered that the car would not start. The suffering driver, who lost his additional income, was sent to look for other ways to solve this issue.
The story began with Gazelles and Sables with 405 engines installed, which consumed a lot of fuel. It was these motors that began to stall when the craftsmen tried to wind the odometer. The technique for effectively hacking a device is very simple. To the ECU (electronic control unit) of the car, you need to connect the Combiloader PAK, from which a special serial engine control program is read.
Then we open the program CTPro and in the menu from the listed configuration, uncheck the box next to the speed sensor. According to this algorithm, an already modified engine control program is written to the computer with minor changes.
After such actions, you can call a good friend of an auto electrician who will connect the wire from the generator to the instrument panel odometer, and the process will go faster, you yourself will be able to wind the required number of kilometers. But this method is already gone. Today the world is saturated with advanced gadgets and all kinds of electronics.
Using the method volumetric installation, a simple generator is made, which consists of three radio elements (see electrical diagram).
Toggle switch S1 is needed to switch the electrical signal going to the instrument panel, either from our generator or from a standard speed sensor. Our generator receives voltage from the "plus" of the ignition switch. This allows you to wind up the mileage without starting the car (it will be enough just to turn on the ignition). You can also turn on the circuit to work right when the car is moving.
Automotive electrician will definitely recommend that you solder another resistor in series with the trimmer in the circuit. This is necessary so that when the regulation is directed to the extreme left position of its engine, the process of generation failure does not occur.
Also, a protective diode must be present in the circuit to protect the electrical circuit from polarity reversal. The values of the resistor and capacitor indicated in the diagram are quite suitable for generating rectangular pulses with an amplitude of 12V, in the low and high frequency range (from 180 Hz to 1.5 kHz). These characteristics more than cover the needs of this device on different cars.
For immediate change frequency range, the capacitor needs to be replaced. As the capacitance decreases, the frequency increases and vice versa.
The following circuit, with the same principle of operation of the generator, is built on a 555 microcircuit (1006VI1).
It should be remembered that all the variants of the circuits given in this article were developed for a voltage of 24V in a KAMAZ truck.
The figure shows a generator circuit for 176 (561) LA7 or HEF4011.

Before proceeding to some changes in the electronics of your car, you need to complete all of the following items. Our task is to find the necessary wiring, through which information about the car's mileage is digitally transmitted to the instrument panel odometer. The following describes the procedure step by step:
1) ——- Inspection of the gearbox, rear axle, front-wheel drive (if the car is front-wheel drive) in order to detect a speed sensor.
2)——— If you find something similar on the speed sensor, but are not sure that it is he, then you need to test it. To do this, you need to remove the connector from it and drive a few kilometers. You should find that the speedometer or odometer has stopped working. If this did not happen, then you did not disable the vehicle speed sensor, but something else.
3) ——— In this case, if you find a three-wire speed sensor, then it is imperative to measure the voltage at its connector in order to determine the signal wire. Next, this signal wire must be called on the dashboard. A winder will need to be connected to the end of this wire. To do this, you need to hang out the drive wheels of the car and make them spin, in parallel with this, control the signals passing to the dashboard using an oscilloscope.
4) ——— If the speed sensor could not be detected in the first paragraph, then the odometer probably receives a speed signal from the ABS. In this case, the only option is to look for the signal output on the instrument panel using an oscilloscope.
If you have on hand detailed information materials, electrical circuits for the model of car that you are going to do “chip tuning”, then the task is quite simplified. It must be remembered that each car of different manufacturers is individual. You are entirely personally responsible for your actions. Therefore, before proceeding with the connection of the selected wires, you need to double-check everything several times.
In this brief overview on the winding of the odometer, the general principles for solving the problem set before us are highlighted. The specific implementation, on a specific car of a particular model, may differ greatly in favor of complication. If you have already had experience with another type of car that is not yet on our list, send us the information and we will gladly add to our table.
Some subtleties on creating an odometer winder for Ford Mondeo and Ford Focus cars of 2006, as well as Toyota Camry.
These car models use the signals coming from the ABS as a vehicle speed signal. The type of sensor used on these cars is current, which means that the current in the circuit changes when the wheel rotates. Changes occur in the range of 7 - 14mA. If you connect an oscilloscope in parallel to the sensor, then when the wheel rotates, we will get a meander swing of about 0.5 V, with standard values of 12 V. Below is a circuit that completely simulates the operation of such a sensor.
On the Ford Mondeo and Ford Focus models, we can determine the positive wire using a voltage tester by removing the connector and working with the wire with the ignition on. In this example, we have used the full (manual) recommutation effect. To wind the odometer, you need to open the hood, then remove the plug from the connector, and in its place we connect the winder.
Turn on the car ignition and we make the necessary winding. After performing the necessary actions, we connect plugs to the connectors that restore the factory connection of the ABS control unit with the sensors. All these wires could be switched to the relay, but as a result of our actions, a lot of extra wires would have appeared. When testing and operating our odometer wrapping system, two driving wheels should be used, because when one wheel is running, the speed indicator will not exceed 30 km per hour.
The car model TOYOTA CAMRY, produced in 2006, has a dashboard called "optitron" and has a neon backlight. The engine capacity is 3.5 liters, the gearbox is automatic, the speed signal coming to the odometer is taken from the ABS and has the form of a sinusoid with an amplitude of 1V, with a frequency directly proportional to the rotation speed. This vehicle uses an inductive type ABS sensor.
electrical diagram, which we need to wind the odometer, must be built using the KT3102 transistor. A resistive divider performs operations on the amplitude of the output signal, thereby reducing it. A capacitor with a capacity of 0.1 uF to 0.47 uF removes the DC component of the signal.
We remind you that it is not recommended to interfere with the operation of the ABS system, but if you nevertheless made decisions, then you must fully understand the consequences and, in accordance with this, perform the work at the proper quality level.
DEVICES CAR GAZ-53-12
Car speedometer GAZ-53-12
The SP135 speedometer consists of a pointer speed indicator and a total distance meter.
The speed indicator has a scale from 0 to 120 km/h with a division value of 5 km/h. Its mechanism consists of a permanent magnet mounted on a drive shaft and an aluminum coil mounted on an axle. An arrow is mounted on one end of the axle, and a sleeve with a spiral spring-hair is pressed in the middle part. The inner end of the hair is fixed on the sleeve, and the outer end is fixed on a plate that serves to regulate the tension of the hair during factory adjustment of the speed indicator. The axle rotates freely in two bearings.
The screen around the coil is designed to increase the magnetic flux passing through the coil. When the magnet rotates, the magnetic lines of force, crossing the coil, excite an electromotive force in it and create their own magnetic field. The interaction of the field of a rotating magnet with the field of the coil creates a torque that drags the coil in the direction of rotation of the magnet. This moment is balanced by a spiral hairspring.
Thus, the coil, together with the axis and the arrow, rotates through an angle proportional to the number of revolutions of the speedometer roller, i.e., through an angle
corresponding to the vehicle speed.
The total distance meter consists of a system of worm gears and drums associated with it. The drums have teeth on the inside of the rim and are interconnected by pins placed between each pair of drums on brackets. On the outer side of the rim of the drums, numbers from 0 to 9 are applied at regular intervals. The total counter has six drums, and the daily counter has four, of which the rightmost one shows tenths of a kilometer and differs in color from the other five drums.
The maximum reading of the total counter is 99999.9 km, after which the readings start again from zero.
For 1 km of the distance traveled, the axis of the magnet and, accordingly, the magnet make 624 revolutions. The direction of rotation of the magnet axis on the drive side is left.

Movement to the speedometer is transmitted by a flexible shaft GV20-D1 from the gearbox. The flexible shaft is of a non-separable type, i.e. its flexible cable cannot be removed from the sheath.
The control lamp for turning on the main beam of the headlights is installed in the speedometer housing.
Caring for the speedometer and the flexible shaft of the speedometer in operation consists in a number of operations, which are:
Checking the reliability of tightening the nuts connecting the flexible shaft to the speedometer and to the gearbox. The nuts must be hand-tightened to failure, and the slack in the fastening of the tips of the flexible shaft shell should not be felt when they are rocked by hand;
Checking the correct installation of the flexible shaft. The flexible shaft of the speedometer on the car is mounted so that the radius of the bends is at least 150 mm.
It should be taken into account, especially when changing the flexible shaft, that the presence of sharp bends leads to a reduction in the service life of the shaft and, in addition, can cause the speedometer to fluctuate and knock. Therefore, when inspecting the car, you should check the correct installation of the shaft. The shaft must be fixed with brackets and must not have sharp bends, especially near its ends.
Steep bends of the speedometer shaft near its ends are the result of excessive tension on the shaft.
In the event of a cable break, before installing a new flexible shaft on the vehicle, make sure that the cause of the cable break was not a jam in the speedometer. To do this, attach the end of the flexible shaft to the speedometer and slowly turn the free end of the cable by hand. In this case, no jamming should be felt, and the speedometer needle should not deviate from the zero division. When the cable is turned sharply in the direction of its rotation when working on a car, the arrow should sharply move away from zero, and then easily return back.
If the speedometer roller is stuck, the device must be replaced with a new one.
The fluctuation of the arrow of the speed indicator over a wide range during the operation of the speedometer occurs most often due to:
Incorrect installation of the flexible shaft (bends having a radius of less than 150 mm, the flexible shaft is not attached to the proper place);
Insufficient amount of lubricant inside the flexible shaft shell. In this case, the shaft must be lubricated as indicated below;
The absence of longitudinal movement of the cable inside the shell with the nut fastening the flexible shaft to the speedometer tightened to failure. If there is no longitudinal movement, the speedometer drive shaft is pressed by the cable into the device. During prolonged operation in such conditions, the adjustment of the speed indicator is violated, and then the device itself fails, if by that time the cable has not broken.
If the speedometer (both counting and speed units) stops working, you should check if the cable is broken.
The longitudinal movement of the cable is checked by swinging the free (not fixed) end of the cable from the side of the gearbox. The disappearance of the longitudinal movement of the shaft cable, which worked for a long time, is explained by the ingress of dirt into the hole in the speedometer roller.
This dirt must be removed. It is also necessary to clean the junction of the other end of the cable from dirt and only after that attach the shaft.
Speed control is one of the foundations of successful and safe driving. Especially for solving this problem, a device is installed in the car, which is known even to people far from technology - a speedometer. About the design of speedometers, their functioning and features of their use - in the article.
auto). Such a speedometer measures the angular speed of rotation of the gearbox output shaft or the wheel axle and, using the simplest mechanism, calculates the speed. The mechanical speedometer is divided into four key nodes - the speedometer speed node (provides a display of the current speed), the gear vehicle speed sensor (or simply DSA), which connects their flexible shaft and the odometer with its mechanical transmission (connected to the flexible shaft). The main part of the speedometer is a high-speed unit, which uses magnetic induction. The assembly consists of a cylindrical permanent magnet that closes it on top of an aluminum cup and a spring that holds the cup in a certain position. The magnet is connected to a flexible shaft, and the glass is connected to the speedometer needle displayed on the instrument panel. When the magnet rotates, eddy currents arise in the surrounding aluminum cup, they interact with the magnetic field of the magnet, and as a result, the cup also tends to rotate.Speedometers of the Vladimir plant Avtopribor
