Performing a Timed Run
After configuring and selecting your ride, you are ready to make a timed run. This is the basic test which generates all of the results Dynolicious records for your vehicle.
- Go to the “Timed Run” tab.
- With your phone properly mounted as described in the section on mounting your iPhone, stop your vehicle, and press the “Test Start” button.
- The button will briefly turn yellow and say “Calibrating”. During this stage, Dynolicious is determining the orientation of the device. It is critical that you do not move the device during this step.
- The button will turn green and say “Go!”. You may now start your test at any time.
- Upon accelerating, the test will automatically start. You will see the Elapsed Time indicator counting, and your current speed displayed on the speedometer.
- The graph provides a visual display of Horsepower, Speed, and Acceleration. If the green Horsepower line is flatlined, it most likely means you did not configure a weight in you vehicle profile.
- The bar at the right of the speedometer indicates the distance travelled. As times are recorded for 60 feet, 330 feet, 1/8 mile, 1000 feet, and 1/4 mile, the corresponding segments will light up.
- The test ends when you reach 1/4 mile, when you decelerate by 10 MPH, when you press the “Cancel Run” button, or when 30 second has elapsed.
Tips for Accurate Results
For most accurate test results, please adhere to the following guidelines:
- Follow the mounting guidelines provided in the section on mounting your iPhone. Mounting is the most critical aspect to achieving accurate results.
- Run calibration from the setup menu. The accelerometers in the iPhone are temperature sensitive, so it is best to run calibration in your car, with the engine off (for vibration), under the same temperature conditions as you perform the test run.
- Make sure that your test surface is fairly level. If you start or end facing uphill or downhill, this will significantly affect your numbers.
- If your aim is to measure HP, try not to jerk the car at takeoff. A smooth acceleration at takeoff and then wide open throttle will generate the most consistent results.
- Make sure that the weight specified includes all passengers, cargo, fuel, accessories, etc.
- Make sure the iPhone is mounted so that it cannot move relative to the car. Cradles that bounce while driving have a serious effect on accuracy.
- If you believe you are getting false triggering, meaning that the timer starts before you start accelerating, please increase the trigger value in the setup menu.
Multiple Vehicles
If you have multiple vehicles set up in Dynolicious, you can easily cycle through the vehicles by tapping the button to the left of the current vehicle.
