200Km/H ACC GPS Speed Limiter


Vehicle speed limiter YTWL_CA100F is an intelligent terminal equipment which can realize precise speed limiting for vehicles. It is not only a speed limiter but also a GPS Tracker. The product adopts ARM intelligent chip. Speed control precision is very high and the performance is reliable. It will not affect the throttle start nor the power torque, stable and reliable. It only limits the maximum speed and the vehicle will not stall during speed limiting, and ensure the throttle pedal free movement in the right speed range.

It also reserves abundant interfaces and it can work together with a variety of external equipment with high compatibility and performance.






6: brown line, 8: Orange line, is the line of the buzzer,

9: Gray line, pick up the pulse line of the original car, connect the pulse line speed limiter, the speed limit function will not have too much delay, use GPS signal speed limit, there will be a delay of about 2 seconds

10: ACC line 11: Power ground

12: Positive power supply

Except for the 4 wires of 6, 9, 11, and 12, which are necessary wiring, the other wires are reserved functions and are used for subsequent development of other functions.

2. The install steps:

3.1 Find the vehicle accelerator pedal line harness at first, then find the two signal lines from the six lines with multi-meter test.

There are six lines in the accelerator pedal interface, two power lines, two ground lines, and two signal lines. Start the vehicle, step on the accelerator pedal, let the vehicle in idle state, then the signal line voltage value will change, thus you can find the signal lines.

Please see the picture below


3.2 Cut the two signal lines, and then connect <10brown line+9yellow line> and <4blue line+3white line> to the signal lines respectively.

Please note that as shown in the figure following, 10brown and 4 blue line are connected to the part close to the ECU, 9 yellow and 3 white are connected close to the accelerator pedal.


3.3 Find the speed pulse signal line of the car, connect to the 9 gray line of the GPS speed limiter, connect the speed pulse line, and the speed limit delay time is within 1 second.

3.3.1 How to find the speed pulse line:

With an oscilloscope, a square wave appears when the car is started. The square wave is wider when it is static. When it is accelerated, the waveform is narrower and changes according to the speed. The output waveform is about 0.5V-12V.

3.3.2 The main position of the speed pulse line is in the following sections:

A. behind the dashboard

B. Audio host part

C. Gearbox output

D. Driving computer parts

E. ECU electric unit

3.4 Set the limit speed.

3.4.1 After GPS SPEED LIMITER is installed completely, start the vehicle first. When the vehicle is idling, send a text message “STARTIDLE*123456”, the device will automatically learn the idle voltage, and then return the learned idle voltage value to the mobile phone.

Then use the text message "SPEED*123456*xxx" (for example: SPEED*123456*050, means to set the speed to 50km/h) to set the speed limit, first test it with GPS speed, and if the speed limit functions normal.

3.4.2 Calibrate the pulse coefficient.

You can find the original car speed pulse line to be connected with the device’s pulse line. Then you can make the car run at a constant speed of 30km/h, then press the button twice to calibrate the current pulse coefficient.


Please be noted: same vehicles have the same pulse coefficient.

The default pulse coefficient is 450.

If you already know the pulse coefficient of a type vehicle, you can set it directly by SMS.

PULSE*123456*26 (Note: this command sets the pulse coefficient to 26)


3.4.3 Set the value of Speed Limit. Send command: SPEED*123456*080 and the device will reply with: Set Speed OK: 80

This command sets the speed limit to 80KM/H. You can set the speed value as low as 20KM/H whose command shall be: SPEED*123456*020 and so on. Or you can also set the speed limit from platform when device is online, as follows:





3.4.4 How to find the car speed pulse line.

The principle is: when a voltage is applied to the pulse line, the speed pointer on the car dashboard will move, or the speed indicator of some cars will not move, but the odometer of the car will increase. Based on this principle, we designed a tool specifically for finding pulse lines and this tool will be available upon formal order.


Start the vehicle at idle speed, insert the tool into the cigarette lighter port, connect the tool's GND line to the car's GND line, and the line behind the instrument panel, you can use the needle on the tool to tie one by one. When the speed indicator needle will move, Or the car odometer will increase, so that you can determine that line is the original car speed pulse line.

3.4.5 Pulse speed on platform.

From platform, you can see the speed limit value and the pulse speed value




3.5 For the Mechanical throttle, need add the relay.

3.5.1 Need use a relay; the signal wire of the relay is connected to the white wire (the end of the white port is marked with: mechanical throttle). When the speed exceeds the set speed, the throttle will be disconnected for 15 seconds, and after 15 seconds, the power will supply Oil for 2.5 seconds, then disconnect fuel and refuel, until the speed drops below the set speed (this 15 seconds is not fixed, you can modify the oil cutoff time for different models, such as this command: oiltime*123456*5 (Modified the disconnection time to 5 seconds)


3.5.2 How to connect the relay.

First cut the fuel pump line so that one end of the fuel pump line has voltage: we call fuel line +, and the other end has no voltage in the picture showed: fuel line of pump side

85pin(yellow line)and 30pin (green line)connect to: fuel line +

86 (white line) connect to the white wire of the speed limiter: mechanical throttle line

87(green line) connect to: fuel line of pump side.

Note: Control the speed of the speed limiter with above way, the delay of the speed limit will be relatively large. For example, if the speed limit is set to 40km/h, the car can also run up to 50km/h during acceleration. So, find the car pulse speed line and calibrate the pulse speed, the delay will be much smaller,

For vehicles with mechanical throttle, if want to limit the speed without delay, need connect a solenoid valve and use a relay to control the solenoid valve to achieve the purpose of real-time speed limit.

Solenoid valve picture:


3.5.3 Installation method: In principle, it is the same as installing a relay, but it is necessary to cut off the oil pipe of the oil pump, and then both ends of the oil pipe are connected to the two ends of the solenoid valve. In this way, when the vehicle with a mechanical throttle exceeds the speed limit value, it will disconnect the oil circuit When it is lower than the speed limit value, the oil circuit will be restored.


3.6 Yellow line 4: After the vehicle is stolen, send command to cut off the fuel of the car remotely, command is : cutoil*123456, and refuel command is: supplyoil*123456


3.7 Limp mode testing:

When cut off the car speed pulse line, the car will be limit to max speed is 30km/h, this speed will use the GPS speed.

When remove the whole white head connector, the car also will limit to 30km/h.

Note: If it is a mechanical throttle vehicle, the white wire of the BH (black head harness) must also be connected to the relay. When the WH (White head harness) is removed, the white wire will control the relay to limit the speed. And the black wire of BH also need to connect the GND of the car


4. LED indicator

4.1 The red light is the power indicator. If it is steady, it indicates that the main power is on, and the off indicates that the main power is off.

4.2 Blue is the GPS indicator, always on indicates GPS positioning, and off means that GPS is not positioned.

4.3 Green is the system indicator. If it is steady, it indicates that the GSM network is not registered. Flashing indicates that the GSM network has been registered. Flashing twice indicates that GPRS is connected.


5. Key operation:

5.1 Press and hold for more than 3 seconds, the buzzer will sound and export data to the U disk.

5.2 Press the button 3 times continuously, the buzzer will sound and output data to the printer.

5.3 Press the button twice continuously, the buzzer sounds 2 times, and the current pulse coefficient is automatically calibrated.


6. Bluetooth printer:

Printer power light--Blue light if it is steady light indicates Bluetooth connection is normal, if blue light is off, Bluetooth is not connected
