Parameter Setting

Parameter Adjustment - power parameters matched with the engine

The X Thruster achieves optimal combustion efficiency in the engine through adjustable power parameters. Considering variations in air oxygen content, fuel quality, and engine conditions in different regions, we have designed flexible power parameters to match the engine’s optimal configuration. The parameter settings take into account the following factors:

  1. Intake method: Natural or supercharged.
  2. Fuel type: Gasoline or diesel.
  3. Connection position: Air filter housing or intake pipe.
  4. Single cylinder displacement: For example, 500cc, suitable for 4000cc 8-cylinder or 2000cc 4-cylinder engines.

Based on the analysis and R&D data, we have set the parameter “initial values” for different displacements. Please use these “initial values” as recommended by the dealer.

Note: Improper parameters may affect fuel efficiency and system performance. Please refrain from making arbitrary changes to ensure optimal system performance.

Parameter Correction - why power parameters need to be rematched

The X Thruster reduces carbon deposits through nanoscale oxide crystallites and clears existing deposits at high temperatures. Over time, the carbon deposits inside the engine will peel off, restoring engine efficiency, and requiring adjustments to the nanoscale oxide quantity.

Therefore, users need to adjust the power parameters to ensure optimal combustion. It is recommended to check the parameters after driving for 3000 km and adjust them according to the vehicle mileage and condition. If there are changes in fuel quality or if the performance feels inadequate, parameters can be adjusted accordingly.

The parameter adjustment unit is “0.1,” and you can adjust it using the X Thruster app. During driving, please ensure safety by having the co-driver operate the app or seek assistance from the dealer.

Parameter setting guidelines - small car (gasoline and diesel engines with displacement below 6000cc (inclusive)):

  1. According to the “parameter adjustment” principle, obtain the “initial value” suggestion from the dealer.
  2. Start the engine, and after the engine reaches the operating temperature, set the “initial value” through the app.
  3. Drive your vehicle on expressways or other roads with less traffic control or traffic. at speed > 60 km/h use app set the “initial value”+ / – 0.1 ~ 0.2, with each The parameter change setting of 0.1, the feedback status of the vehicle is as follows:


    After the vehicle accelerates, release the accelerator pedal, the engine speed drops slowly, and the vehicle glides farther.

    Stepping on the accelerator pedal lightly, the engine responds sensitively, the speed rises easily, and the speed increases quickly.

    The engine vibration is reduced, the engine sound is crisp, and the performance is improved. Some automatic vehicles may shift gears in advance (torque change).

    The emission of toxic exhaust gas (CO, HC, NOx) is reduced, the amount of water vapor in the gasoline engine exhaust gas increases, and the sour odor and black smoke in the diesel engine exhaust gas are reduced or eliminated.

    In high altitude hypoxic or high temperature areas, engine power is less affected.

  4. If the feedback of the above vehicles cannot be confirmed on ordinary roads, it is recommended to drive the vehicle on the highway. At speed >90 km/h, Drive a certain distance at a constant speed, cruise at a constant speed, set the “initial value” + / – 0.1 ~ 0.2 through the app, and confirm the parameters with a parameter change of 0.1 each time. Accelerate a little under the condition of constant speed, and the vehicle will have the best response after accelerating. Sensitive feedback is the most ideal parameter value.
  5. The above steps can be repeated within the range of +/- 0.1 ~ 0.2 until the optimal response of the engine occurs, that is, use the product at this power parameter for at least 3000 km, or until the optimal engine response is blurred, and then re-calibrate the parameters.
  6. If necessary, the power parameter is set to 0.0 and the “best parameter value” can be exchanged to achieve two states of “off” and “on” of the propulsion system, so as to feel the difference in vehicle performance between the two.
  7. If it is a manual transmission vehicle, it is recommended to use a fixed gear (such as 3rd or 4th gear) at a stable speed to confirm the smoothness of the engine response during acceleration.

Parameter setting guidelines - large vehicles (diesel engines with a displacement of 6000cc and above):

  1. According to the “parameter adjustment” principle, obtain the “initial value” suggestion from the dealer.
  2. Start the engine, after the engine reaches the working temperature, quickly depress the accelerator pedal two or three times without entering the gear, observe the rising speed of the pointer of the engine tachometer, and feel the engine sound of the engine speed rising. At this time, the system parameter is 0.0, The thruster has no effect, and the vehicle response is the original car state.
  3. The “initial value” setting is completed through the app.
  4. As in step 2, quickly press the accelerator pedal two or three times without entering gear, observe the speed at which the pointer of the engine tachometer rises, and feel the sound of the engine speed rising. Setting “Initial value” + / – 0.1 ~ 0.2, adjust each time the parameter changes by 0.1, and repeat the above steps to find the smoothest and fastest response of the pointer of the engine tachometer. At this time, the engine sound should be the most delicate when the engine speed increases . This is “Stationary Parameter A“.
  5. Drive the vehicle to the road, reduce the “stationary parameter A” by 0.1 ~ 0.3 through the app while driving, and adjust it with each 0.1 parameter change to find the vehicle with the smoothest acceleration during driving. This is “driving parameter B”.
  6. According to experience, “driving parameter B” may be the same as “stationary parameter A“, or “stationary parameter A” minus 0.2 = “driving parameter B“.
  7. If it is a manual transmission vehicle, it is recommended to use a fixed gear (such as 3rd or 4th gear) at a stable speed to confirm the smoothness of the engine response during acceleration.
  8. After obtaining the “driving parameter B”, the feedback status of the vehicle is as follows:


    The vehicle starts and accelerates briskly, and there is no need to downshift in some climbing sections.

    The odor of exhaust gas has become lighter, and the amount of urea (SCR) used in some vehicles has been reduced.

    White smoke and odor reduction for the DPF Diesel Particulate Filter regeneration process.

    Engine vibration and noise are reduced.

    In high altitude hypoxic or high temperature areas, engine power is less affected.

  9. After obtaining the “driving parameter B”, drive at least 1500 km with this power parameter, or until the engine response is blurred, and then re-calibrate the parameters. Usually, “minus 0.1” is a more possible option. In some cases, no adjustment is required, or Parameter correction is required only when more miles are driven to meet the current engine state.
  10. When static emission testing is required, please add 0.2 to “driving parameter B” for testing, and then return to “driving parameter B” after completion.
  11. After completing the first setting, when the vehicle continues to drive and needs to be calibrated for “driving parameter B“, the engine should have changed. After completing the parameter calibration, you can start to observe the fuel consumption. Under normal conditions, when the engine efficiency increases, the fuel consumption will change.

Parameter error - Inappropriate parameter setting.

Due to the vehicle’s own air-fuel ratio adjustment mechanism, the O2 sensor on the exhaust pipe will detect the oxygen content of the exhaust gas. If the system power parameter is wrong and the catalyst is excessively vaporized, the engine will be forced to increase the fuel injection amount, resulting in excessive fuel concentration. , increased fuel consumption, slow engine response.
