Step by Step

How to Use Microdyno

Get accurate dyno results in minutes

01

Setup Your Vehicle

Configure your Vespa's specifications in the app. Enter your gear ratio, tire size, and vehicle weight for accurate calculations.

Gear Ratio: Total ratio from engine to wheel Example: Primary (2.86) × Secondary (4.2) = 12.01
02

Position Your Phone

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.

03

Perform the Test

Start recording, then accelerate from low RPM to redline in 3rd gear. Maintain full throttle throughout the pull for accurate measurements.

Safety: Always perform tests in a safe, controlled environment ✓ Use 3rd gear for optimal results ✓ Warm up engine before testing ✓ Phone safely stored in backpack
04

Trim to 3rd Gear Run

Trim your recording to isolate only the 3rd gear acceleration run. This ensures accurate analysis by removing idle time and gear changes.

05

Edit Harmonics

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.

06

Analyze Results

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.

How Do I Use Microdyno?

Place your phone in a backpack, start recording, then perform a full-throttle acceleration in 3rd gear from low RPM to redline. The app analyzes the engine sound to calculate power and torque.

Why Microphone Permission?

Microdyno analyzes engine sounds using FFT algorithms to determine RPM precisely. The microphone captures the audio frequencies needed for accurate power calculations.

Is Location Required?

No, location is optional. It's used to fetch weather data (temperature, pressure, humidity) for more accurate measurements, but you can use the app without it.

Only Vespa?

While optimized for Vespa scooters, Microdyno works with any engine. Configure custom gear ratios and specifications for motorcycles, cars, or other vehicles.

Measurement Accuracy?

When properly calibrated, results are within 5% of traditional dyno measurements. Accuracy depends on correct gear ratio input and clean audio recording.

Can I Export Data?

Yes. Save unlimited dyno runs, export graphs as images, and track performance changes over time. Perfect for documenting modifications and tuning progress.
