According to the automotive norms, input and output signals are protected. Optical isolation protects the computer. Operating voltage 5V USB.

General Appearance:

      

You will see such a Screen when the program starts running on your computer as in the Picture.From the menu at the top of the screen, you can switch to the appropriate page by clicking on one. In this manual, we will explain Each of the menu in detail. At the bottom left of the screen image, and the USB cable image that is written in green colour "Connected to ECU" message, shows that USB cable is plugged and the ECUs programming cable is also in communication with the ECU. When USB cable is not connected or unable to communicate with the ECU, a warning message will also appear in this field. Right at the bottom of the screen and a black coloured "Language" section of the program, you can access the language option and the program can be used by replacing any of the selected language.

Link Building to ECU:

18

Please connect the USB cable to the ECU and to your computer, for starting the communication with the ECU.

Connect the USB cable to the computer.

The other end of the cable should be connect to the wiring harness.

After making the wiring installation , please switch the vehicle's ignition key in order to start working with the ECU. Then you can run PC program.

Parameters page:

19

By using the “Parameters” page , various data of the vehicle can be viewed and the car can be switched to gas or gasoline.  

Blue graphics and text shows Petrol injection times of each petrol injectors.Green graphics and text shows Gas injection times of each gas injectors.While the car is on petrol mode, this zone seen as zero value. Temp shows the temperature of the gas regulator.Gas Pressure shows the Regulator’s outlet GAS pressure. Manifold Pressure shows the intake suction manifold pressure.RPM This zone shows the engine RPM value. (If engines RPM signal connected)Supply Voltage shows the voltage of the engine.

In the lower right side of the screen , you can see the "changeover switch key" icon and by clicking the image, the vehicle can be used by gas or gasoline. Moreover, the amount of remaining gas in storage tanks is indicated by the switch key again.

Vehicle's gas and manifold pressure, is measured by "Manifold Pressure (MAP) Sensor". Defected or improper MAP sensor, will have a negative effect on the operation of vehicle.

Automatic Calibration Page:

20

"Auto Calibration" tool, automatically makes the required calibration according to the parameters of the newly established system. Manual Calibration may take a little more time and it is more difficult. Making the necessary calculations require some experimentation. For this reason, the calibration process should done automatically by a computer which is much more accurate.

 

In the lower part of the automatic calibration page, you can watch in the tool boxes all the parameters of the vehicle, and also there is a “switch key” button where you can pass to gas or gasoline. To start the automatic calibration, clicking "Start Calibration" button is enough.

     What to do before starting calibration.

21

Before starting the calibration process, (lights, air conditioners, fans, radios, etc..) should be switched off. If the car has an automatic transmission, the gear sould be natural (N) position.

Vehicle has to run on petrol mode and at least A few minutes should be spent on petrol and vehicle operating parameters should be expected to become a balanced and stable, this is important.

The regulator temperature of the vehicle should be 50 ° C or above. If the temperature is not high enough, the program will not start the automatic calibration process.

During automatic calibration , manually do not pass to gas or petrol, ‘cause the computer will automatically examines the parameters of gas and petrol mode.

During the automatic calibration the load of the car should stay constant , this is very important, otherwise, calibration parameters of the vehicle may be calculated incorrectly. During calibration , the vehicle radiator fan or opening of the vehicle headlights will result in failure and in such cases, the calibration must be done again.

After the calibration process is successful completed, the program will notify you a message. If you have used an inappropriate Injector Nozzle diameter, program will ask for an enlargement or reduction of the required diameter will be reported.

When any Changes were made to the nozzle diameter or gas pressure value , then automatic calibration should be done again.

Map Setup Page:The vehicle's performance while working in gas mode can be fully adjustable by using this page. Traction and the vehicle's gas mixture enrichment or impoverishment may be determined by making some changes on this page. To be a master On this map page, for a while a lot of exercises are proposed to the installers.

22

To get the vehicle switch to gas or gasoline, and to view the parameters, there are a lot of tool boxes. By using the Graphic image tool, you can adjust, as needed gas injection to the value for given gasoline injection time. A linear graph is always recommended but in some vehicles when at the gas mode during in load, the performance might be reduced, therefore it is possible to get a beter result by making a variety of graphics changes and this will make the curve close to the ideal.

By Clicking, the “Save to ECU”s button; the prepared curve and alpha, offset values are transmitted to the ECU's memory. After any changes in this page, you should click this button.

By clicking “Load from ECU”s the button; ECUs memory and the values obtained in the curve are installed on the computer screen. Each time “Map Setup page” is opened, it automatically loads all the information inside the ECUs, to the screen.“Save to file” by clicking the button, the prepared curve and parameters can be saved to the computer for a later use.

Click the “Load from file” button ; previously saved and setted curve to a computer, can be installed to the screen.

Alpha value; makes the adjustment of the vehicle's fuel injection, in which rate gas injection will be converted. Alpha value should be within a certain range. that is would be 1:00 in ideal conditions, but the tool can be set according to the state of the vehicle. Curve is steeper when the value of alpha increases, however whehn the alfa decreases, approaching the curve is horizontal.

The boundaries of Alpha value:

Alpha 0.00 - 0.75 large nozzle size, reduce the diameter.

23

Alpha 0.75 - 0.90 the diameter of the nozzle is appropriate, but reduction of the nozzle size is recommended.

Alpha 0.90 - 1:10 the nozzle diameter is appropriate. (Ideal value 1.00)

Alpha 1:10 to 1:25 the nozzle diameter is appropriate but the enlargement of the nozzle diameter is recommended.

Alpha 1:25 to 1:50 nozzle diameter is small , then the diameter should be enlarged.

To calibrate the offset value of the vehicle in idling is set automatically by the automatic calibration. Changing the value which was assigned by the automatic calibration, means to interfere the idle calibration. If the offset value should be changed, the car’s idle position should be observed. By examining, the offset value which has been assigned by the Automatic calibration, it is possible to understand whether the nozzle size is appropirate or not.

The boundaries of the offset values:

Offset 0 - 1.5 large nozzle size, reduce the diameter. . Offset 1.5 - 2.0 the diameter of the nozzle is appropriate, but reduction of the nozzle

size is recommended.

Offset 2.0 - 3.0 the nozzle diameter is appropriate. (Ideal value 2.5)

Offset 3.0 - 3.5 the nozzle diameter is appropriate but the enlargement of the nozzle diameter is recommended.

Offset 3.5 - 5.0 nozzle diameter is small , then the diameter should be enlarged.

Any changes to the offset and the alpha values will affect the car idling injection. At the end of the Adjustments, when working on gas and petrol, the fuel injection period is required to have the same values. As an example, if the injection of vehicles used in petrol mode is 3.0ms, when the vehicle is is used in gas mode it must be 3.0ms pterol injection time."petrol injection time during in petrol mode = petrol injection time during in gas mode

If all the conditions hold true , the calibration means true.

MAP breaking curve:

24

Map page curve , can be marked by the shattering from 5-point curve and can be regionally changed. Graphics raising or lowering of certain areas, of vehicle performance under various loads are used to set regional adjustments. As an example, the vehicles may Work well during in idling, but if the contention is reduced in acceleration, then by breaking the curve of the points (except idle) it is possible to enrich gas injection in heavily loads. The Graphic where you want to break point can be selected by clicking with the mouse pointer. Also you can select by clicking the "location value" boxes. The Desired point (position) can be selected by increasing or reducing the value and it can be adjustable to the desired graphic. Selected points can be changed using arrow keys on the keyboard. Selected point is not just up and down, the right and left by moving to an area more so that adjustments can be made in any sensitive portable region.

The shown the curve belongs to a vehicle where is weak position except idle.   

The example in this picture settings,shows a setting of the vehicle which is good in idle and in mid-load but weak in high load traction, but rather an adjustment made to the car shows also the

25

points in the curve close to each other and making the break up is a delicate.  

In the picture above , Automatic calibration has been made and the alpha and offset values has not been touched. Vehicles were tested in similar load conditions in the drive, and the differences was observed between gas and petrol. The difference in performance can be understood by the driver from a computer that can be followed during such tests. For correcting the difference in the traction, this curve has been set for Petrol and gas.

If the Vehicle in idling and at medium load is good, but if in the high-load , the mixture is coming too rich, and if the emissions are rising or if the vehicle drowned, it is possible to withdraw by breaking the curve downward . This situation can not be encountered regularly.

26

 in the picture below, Wrong Broken curves is seen.

 

This kind of a broken curve will impairs the performance and all the parameters of the car. During the Breaking point , breaking curve shouldnt be very steep and please Take care that to break down the curve in the negative zone , will decrease the car's performance, please remember that.

At any time, After making the adjustments to the curve , by using "Save to ECU" button, store your adjustments to the ECU's memory. in the case of a power failure of the electricity, uploaded settings to the ECU will never be deleted. After adjustments , you can change the vehicle's battery, or you can change the fuses of the car. This will not give any harm to the car.

27

Blue ball: The blue ball which is seen in Graphic screen, shows the vehicle’s applied fuel injection value to the fuel injector and ECUs application of the gas injection value. blue ball normally is Floating on top of the red curve line, but in some cases, may stop at different points. Stopping the blue point at another point is not due to incorrect settings or of any failure , the reason for this is the change of gas pressure in the regulator. Normal value of the gas pressure of regulators is saved to the ECU in the settings page and ECU continuously monitors the regulator. If gas pressure of regulators differ from normal, ECUs' automatically makes the necessary calculations and the vehicle maintains in the same performance. By using the ECU's automatic pressure equalization feature, even if the gas regulator pressure will decrease over some time later, there wont be any change in the performance of the vehicle. Even if the gas inside the tank willfinish, a change will not ocur in automatic return to petrol mode. With this feature, the signal characteristics of ECU seeks to follow in cases of sudden gas to prevent accumulation and exhibits a performance similar to gasoline.

Settings Page:Settings Page , contains ECU's working settings that affect performance. Having the necessary information, while making the adjustments will help to make the necessary correct settings. All set parameters will be described below one by one and you are requested to review them carefully.   

28

The settings screen "Changeover Settings","General Settings", "Pressure Settings","RPM Settings","Level Sensor Settings" and "MAP Sensor" are divided into six sections. In addition, there is an area where you can switch the fuel.

Menus;

Save the file menu and all settings can be saved to the computer.Load from file with this menu, previously saved settings to the computer is installed to the screen. Default Settings menu to reset ECU and settings when generating the return to standard settings are loaded into memory. Save to ECU With this menu , the changed settings is transferred to ECU's memory. Nozzle Table the diameter of the nozzle per liter units in accordance with the engine capacity of vehicle

Nozzle table can be seen in the picture below.

 

According to the vehicle's engine size , from the table you can find out the appropriate nozzle diameter. Recommended the nozzle diameter are for 1.0 bar regulator outlet pressure. If you use a Pressure regulator at a higher value than 1 bar, you must use a smaller diameter nozzle at the same rate you increase the pressure.

29

The new-generation vehicles with the same engine volume can produce a higher horsepower , for that reason , you should use nozzle diameter bigger than 20% than the suggested values. Instead of enlarging the diameter of the nozzle sizes, by increasing the gas pressure regulator , you can also reach the same results. Increasing the Regulator pressure or enlarging the nozzle diameter are same things in terms of performance . because after the automatic calibration, the offset value by referring to the nozzle diameter is smaller , decide nozzle diameter drill instead by raising a bit regulator gas pressure , you can also fix the problem. This reverse process is also true that nozzle diameter come bigger, if you can solve the problem by reducing gas pressure regulator.

Always appropriate nozzle diameter and 1.0 bar pressure is recommended. 

 Attention, Do not miss them ......

Each time you change Gas pressure regulator or injector nozzle diameter , a new automatic calibration is required .

When you change the gas regulator pressure , from the settings menu, by selecting "Normal Gas Pressure" parameter please inform the ECU.

You need to be very careful while Expanding the nozzle , each nozzle drill should exactly be the same with nozzle hole diameter . Do not forget . If nozzles with a dirt inside or a different diameter than another , the gas system will definitely do not work properly.

Factory-drilled and tested nozzles is always recommended.

30

Changeover Settings:

Temp to Switch Gas shows how much time the vehicle will wait to warm up.

Switching to Gas Delay indicates the delay time in seconds that the vehicle has to wait before switching to gas., Even if the vehicle is hot enough, it does not pass to gas until the settled time is over, so that the hot vehicles are prevented from running again in gas directly.

Switching injection time setting , the car with gas, how many seconds to switch the fuel injection is set. Lets consider that this value is 5.0ms, consider that when the car is in idling 3.2ms fuel injection, under these conditions to switch to gas, the driver should pressed on the gas pedal. If change this value as 2.0ms, the vehicles passes to the gas even in its in idling . ( without any need of accleration ) Some old and neglected vehicles can shake while passing to gas in idling. By raising the value,

Minimum injection time ECUs will determine the minimum opening time of the gas injector will. Minimum time of injection, LPG/CNG conversion kit is supplied with 3.2ms for standard injectors. Do not make any change unless it is specifically required to use a different value.

31

General Settings:

Fuel Type with this option, you can be indicate either LPG or CNG will be used in the vehicle.

Engine Type with this option, standard or turbo engine may be selected.

Critical temperature you can set the minimum allowable regulator temperature when the car Works in gas mode. This value is usually 5 degrees Celsius. If the regulator temperature drops below the set value while the vehicle is running in gas mode, ECU will save critical temperature as a failure. This error usually ocur when a sufficient amount of cooling water is unable to reach to the regulator.

Clyinder interval time determines a time setting for each channel of gas cylinder switching one by one delay to gas mode. So that each particular individual Cylinder channel can switch and standby to gas ; thereby you will not feel any shaking.

Start with gas for emergency Check box if want to run the car directly with gas in the first ignition. This usded when the petrol is finished. To run the car directly in gas mode, turn off the ignition key, press and hold on the gas switch key and turn on the starter ignition key. While pressing the starter ignition key, Do not pull your hand over the gas switch key and when the car starts running on gas then you can pull your hand.

Changeover buzzer enabled if you check this box, while passing from petrol to gas, "buzzer" (whistle) short generates an audio signal so that the driver can understand of the gas passes without looking at indicators only through the audio signal.

32

Pressure Settings:

The normal gas pressure value, is the regulator’s gas pressure value. After installation of LPG /CNG kit, while the car is running in gas mode during idling, you can to find out the gas pressure regulator from the "Parameters" page and you can enter this value here.

Minimum gas pressure indicates the minimum allowable gas pressure while the vehicle is working in gas mode. In general, changing is not necessary, but this value can be slightly increased, if the car has some problems switching to petrol when the gas is finished or if it stops. If This value is too much increased, instantaneous and sudden acceleration in gas mode, the system may automatically return from gas to gasoline.

Maximum Gas Pressure by using this parameter, the maximum gas pressure value is adjusted while the car is working in gas mode. If Regulator output pressure, exceeds the maximum gas pressure, due to the high pressure, ECUs will record and saves error to its memory. In Such cases, does not occur in a proper regulator. If the regulator has a poor quality, damaged or fails, in this case, This error will be logged.

Pressure Measurement Period value is a parameter usually do not need to be changed. It can be reduced somewhat if the Vehicle has some difficulties in return from gas to petrol.

33

RPM Settings

In this section you can enable or disable RPM signal input and you can change some settings of RPM signal.

Generally RPM connection is recommended but some cars whic has trouble in electric connection or have unstable RPM signal.

Enable RPM Signal Input if checked LPG/CNG ECU starts using the RPM signal.Cyl. Count setting number of cylinder of engine.Coil Count setting number of coil of engine.Operating Range of GAS section is using set the vehicles RPM range for GAS mode.

For example you can set the values as 1000 < Operating Range of GAS < 6000 for engine uses petrol in car idling and engine uses gas in car running on road. If you set the values like that the engine runs on petrol when RPM is lower than 1000 or higher than 6000.

Inj. Time for High RPM Switch by this section you can change the behavior of ECU, when engine has high RPM. If engine has high RPM and injection time of petrol is more than the value, ECU switch to petrol. If RPM is high but there is not enough injection of petrol, ECU does not switch to petrol even RPM exceed value of operation range thus engine does not switch petrol in low load or N gear.

Hide changeover operation from driver if check this setting, driver will not see changeover notification on gas switch

34

Level Sensor Settings:

Level of sensor type is generaly of "Cangas 1050", and while the ECU produced this sensor is loaded to its memory. Sensor will not make any changes if "No Changes" option is marked. Before any other settings, if you want to install Cangas 1050, please mark "Cangas 1050" option. If you're using A special sensor, and if you are going to make sensor calibration by yourself , please Select this option "Other Settings" . if this will be activated, “the settings” the button will be active and by Clicking "Advanced Sensor Settings" page, you can do the level sensor calibration.

Map sensor:

35

If requested by using the MAP sensor option, you can add new MAP sensor. If there is MAP sensor malfunction and or absence of a MAP Sensor, you can run the vehicle by turning off MAP Sensor option.

MAP sensor can only be temporarily shut down and as soon as a map sensor mounted on the vehicle, the performance, traction will be perfect, and it is very important to automatically switch to gasoline.

Always a convenient and accurate MAP sensor is recommended for a beter performance. 

Advanced Sensor Settings page can be seen in the Picture below.

Sensor calibration can be done manually from this page. The sensor resistant unit should be always KR value. 0-90R sensors are not supported by this system.

On the top of the Advanced sensor settings page, five key can be seen. Boxes at the bottom of these images are used to adjust the resistance range. Resistance meter section of the sensor values can be seen during adjustment. Setting process is briefly as follows; level sensor installed on the vehicle and sensor systems that are connected to the mutlivalve’s float ball and when it is moved and taken key positions in which one is brought to light in that position if necessary. While in this position multivalve values resistance value were measured and the desired resistance is written on the meter box. This process is done for each light level, and by using "Upload to ECU" button it is saved to the ECU's memory. From the menus, the settings are saved to a file stored on the computer. So once you have set a sensor assembly, it can be used to open the same file later for the other installations. At some multivalve sensors, the amount of gas in storage tanks increases, sensor resistance also increases, in some sensors the reverse of this can also happen, the amount of gas in storage tanks

36

increases, sensor resistance can decrease. To ensure the compliance with this type of sensors, from the menu feature you can use increasing or decreasing order sequence.

Car Information Sheet:From this Car information page, you can see, delete and modify the vehicle operating time, trouble codes, times for direct gas mode and the installation informations.

 

Menus:
