DynoMeter

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.


Features:
• 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

Hints:
• 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.
