PerfExpert - Car Onboard Dyno & Timer allows you to measure the performances of your car, such as its real power, torque, and acceleration times. It doesn’t require any connection to your car. Results are provided as detailed reports featuring interactive charts.

How does PerfExpert Dyno works ? It's simple :
1. Create your car profile => Describe your vehicle's specifications, including curb weight, tire sizes, and engine displacement. If you're unsure about these details, we'll guide you through the process.
2. Mount your phone in your car => No need for complicated connections. Simply secure your phone in the car, and PerfExpert will utilize its internal sensors to measure accurate acceleration.
3. Accelerate through the entire engine rev range => Choose a flat, straight, and horizontal road. Accelerate from low revs to the maximum revs while maintaining the same gear. It's that simple!

IMPORTANT : dyno test is not compatible with automatic gearboxes that doesn't have a manual mode.

With such a tool, you can check the efficiency of your various tunings, ECU mapping, chiptuning, and even your chassis settings.

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.
