DynoMeter enables you to measure the performance of your vehicle. Top Speed, Elasticity as well as Timing for 1/4 and 1/8 Mile is possible. For more accuracy in the measurement the acceleration of the vehicle will be used to calculate the speed between GPS updates. The results can be viewed within a local database after each testrun individually for every vehicle profile.
Display of the actual speed in mph or km/h with using GPS/OBD as well as the Acceleration Sensor of your phone.
Acoustic Signals when testrun ist started or stopped.
Display of testrun results with diagram and calculation of the average value. Failed testruns can also be deleted.
OBD-II ELM327 Dongle Bluetooth can be used to read the speed.
High precision in time measurements thanks to the simultaneous usage of GPS/OBD and Acceleration Sensor.
Different testrun types:
Configurable Time Measurement of elasticity 0-60, 55-75, ...
Time Measurement for distance runs like 1/4 and 1/8 Mile
Measurement of top speed
Measurement of Horsepower (experimential)
For activation of a testrun it has to be selected first. After that "READY" occurs. The Measurement will start automatically when the starting speed has been reached or the vehicle is accelerating.
Measurements should only be done under free sky to ensure a good GPS position.
Measurement of speed between GPS/OBD Updates can be configured:
Acceleration Sensor: Usage of the Acceleration sensor to calculate actual Speed.
Speed Delta: Usage of the last measured Speeds to predict the actual acceleration.
Sensor & Delta: The Acceleration sensor as well as the delta of the last measured speeds will be used to compute the acceleration (recommended)
None: Speed will be updated only when new GPS/OBD Data is available.
When the acceleration sensor is used, the backside of the phone has to face preferably straight to the front of the car.
Power measurement should be done in 4th or 5th gear as a gear ratio of '1' will be assumed. You should configure the speed range to your gear ratio in the preferences.
Usage of external GPS is possible with the App Bluetooth GPS.
