PerfExpert 2.2.3

Measure the performance of your vehicle accurately with PerfExpert - Car Onboard Dyno & Timer. This application enables you to assess your car's real power, torque, and acceleration times with precision. The results are presented in detailed reports that include interactive charts, providing valuable insights for tuning optimization.

Utilizing PerfExpert's dyno feature is straightforward:

1. Create your car profile: Input essential details about your vehicle, such as curb weight, tire sizes, and engine displacement for accurate measurements.
2. Mount your phone in your car: Secure your phone within the vehicle without the need for external connections. PerfExpert uses internal sensors to capture acceleration data.
3. Accelerate through the rev range: Perform an acceleration test on a level road from low to maximum revs in the same gear to obtain precise performance data.

Please note that the dyno test is not compatible with automatic gearboxes lacking a manual mode.

This tool enables you to validate the effectiveness of various tuning adjustments, ECU mappings, chiptuning modifications, and chassis settings. By combining the tested car's specifications and device accelerometer data, the application employs sophisticated algorithms to deliver highly accurate performance metrics.

The application offers an array of sophisticated features, including:

• Dyno test: Assess engine power and torque with detailed loss calculations. Identify the engine rev limiter and access comprehensive reports with interactive charts mirroring those from a traditional chassis dynamometer.
• Corrected power and torque calculation based on selected correction standards like DIN, SAE, JIS, CEE, and ISO, accounting for atmospheric conditions.
• Timed Run test: Evaluate acceleration metrics like 0-60mph, 0-1/4mi, 0-100km/h, and more for comprehensive performance analysis.
• Advanced signal processing using your phone’s accelerometer at maximum frequency for smooth performance curves.
• Flexible unit selection: Choose from a wide range of metrics including horsepower, Newton meters, miles per hour, Celsius, and more for personalized reporting.
