2. PerfExpert - Car Onboard Dyno & Timer is an application allowing you to measure the performances of your car, such as its real power, torque, and acceleration times.
3. Detailed reports featuring interactive charts of wheel and engine horsepower and torque / engine speed, just like a regular chassis dynamometer.
4. Using the specification of the tested car and your device’s accelerometer, the application runs our algorithms and dynamic power loss calculations to provide the performances of your car with high accuracy.
5. - Compute corrected power and torque using the correction norm of your choice (atmospheric pressure, ambient temperature and air humidity are taken into account).
6. With your phone firmly mounted inside your car, PerfExpert can rely on its internal sensors to measure the real acceleration of your car.
7. Create your car profile => Describe your car to PerfExpert by providing information such as curb weight, tire sizes or engine displacement.
8. IMPORTANT : dyno test is not compatible with automatic gearboxes that doesn't have a manual mode.
9. Results are provided as detailed reports featuring interactive charts.
10. With such a tool, you can check the efficiency of your various tunings, ECU mapping, chiptuning, and even your chassis settings.
