Measure power of car

Thank you for using my app!DESCRIPTION- With this application you can measure torque and horsepower car engine- The measurement results are stored in the memory of your device and you can view them at any time- In addition, the measurement results can be exported to excel-file- The measurement results can be viewed as graphs, as well as to compare the results of several graphics
HOW IT WORKS- The measurement is carried out using the accelerometer sensor.
Torque and power are calculated from the data obtained with the accelerometer and the said vehicle parameters- Vehicle parameters can usually be found in its detailed technical description- Meters in one gear.
Typically, the best second transfer- In order to measure as accurate as possible road should be as flat and straight- To filter erroneous data from the accelerometer on the rough road temporal filter is applied, the level of filtering can be set in the settings (Inertia accelerometer)
DESCRIPTION OF PARAMETERS- Inertia accelerometer.
Used to filter erroneous values ​​of the accelerometer on the rough road- The rigidity of the suspension.
In sharp acceleration of the vehicle has a longitudinal roll, which depends on the stiffness of the suspension.
This parameter is required to compensate for the accelerometer in roll- Maximum engine speed.
This parameter is required for calculating the maximum power of the engine and to calculate the speed at which the measurement ends- The initial velocity measurement.
With this speed power measurement begins.
Specify it so that it is slightly above the speed at which you turn on your chosen transfer- Transmission gear ratios and tire size it is necessary to specify all cars are different- The air resistance.
Parameter can not change, but for large cars high this parameter can be a little increase- Coefficient of deformation of the wheel.
Parameter can not be changed.
However, for vehicles with high profile tires, this parameter can be increased slightly- Losses in transmission.
Parameter can not be changed.
However, for four-wheel drive vehicles this parameter better slightly increase the
INSTRUCTIONS FOR MEASURING1.
Enter the configuration parameters of your vehicle2.
Secure the device in a stationary state2.
Calibrate the accelerometer to calibrate by pressing3.
When the message "ready to start" gently move your vehicle when you turn on the selected gear, fully depress the accelerator pedal and accelerate up to the cut-off rpm4.
When the speed of the display is equal to the speed at the speed of the cut-off, the measurement is completed, the result will remain
