Transform your smartphone into a precision dynamometer. Developed specifically for Vespa scooters but works with all engines. Analyze performance through advanced audio frequency analysis and get real-time power curves.
Professional-grade measurements using cutting-edge audio analysis
Advanced FFT algorithms analyze engine sound to determine RPM with precision accuracy, detecting fundamental frequencies and harmonics.
Watch power and torque curves develop in real-time. Export data for further analysis or comparison with other runs.
Advanced spectrogram editor allows you to remove noise and unwanted frequencies for cleaner, more accurate measurements.
Configure your exact setup with custom gear ratios, tire sizes, and vehicle specifications for accurate power calculations.
Optional GPS tracking provides real-world speed validation and altitude compensation for the most accurate results.
Save and compare unlimited dyno runs. Track your modifications and see performance improvements over time.
Get accurate dyno results in minutes with our simple process
Configure your Vespa's specifications in the app. Enter your gear ratio, tire size, and vehicle weight for accurate calculations.
Place your phone securely in a backpack during the ride. This positioning protects the microphone from wind interference while clearly capturing engine sound.
The backpack placement ensures safety and optimal recording quality without vibrations affecting the measurement.
Start recording, then accelerate from low RPM to redline in 3rd gear. Maintain full throttle throughout the pull for accurate measurements.
First, trim your recording to isolate only the 3rd gear acceleration run. This ensures accurate analysis by removing idle time and gear changes.
After trimming, use the spectrogram editor to clean up your recording. Remove any noise, vibrations, or interference by tapping on unwanted frequencies in the visual display.
This crucial step ensures accurate measurements. The app tracks the fundamental frequency, and you fine-tune it by removing artifacts for precise power calculations.
View your power and torque curves instantly. The app calculates peak values, shows the full RPM range, and allows you to save runs for comparison.
Export data as images or raw values for further analysis or sharing with your tuning community.
Professional-grade accuracy you can trust
Get help with Microdyno and find answers to common questions
Place your phone in a backpack, start recording, then perform a full-throttle acceleration in 3rd gear from low RPM to redline. The app will analyze the engine sound to calculate power and torque.
Microdyno analyzes engine sounds using FFT algorithms to determine RPM precisely. The microphone captures the audio frequencies needed for accurate power calculations.
No, location permission is optional. It's used to fetch weather data (temperature, pressure, humidity) for more accurate measurements, but you can use the app without it.
While optimized for Vespa scooters, Microdyno works with any engine. You can configure custom gear ratios and specifications for motorcycles, cars, or other vehicles.
When properly calibrated, Microdyno provides results within 5% of traditional dyno measurements. Accuracy depends on correct gear ratio input and clean audio recording.
Yes! Save unlimited dyno runs, export graphs as images, and track performance changes over time. Perfect for documenting modifications and tuning progress.
