DISCLAIMER This is a consumer application designed for general audio analysis and educational purposes. It is not a certified measurement instrument and should not be used where legally compliant or certified measurements are required. For professional acoustic assessments requiring traceable calibration or regulatory compliance, we recommend using an external calibrated measurement microphone with certified sound level meters.

Microdyno measures the power and torque of your motorcycle or scooter with your phone. From the rpm trace of an acceleration run in a chosen gear, the app calculates the curve the way a chassis dyno does, only on the road. Three ways to get the rpm • Microphone: The app reads the rpm from the engine note. In the spectrogram editor you see the fundamental and its harmonics and erase any noise that gets in the way. • Microdyno rpm sensor: A small Bluetooth sensor on the ignition lead reports every spark. No noise, no steps, the most accurate curve. • Lambda sensor: Wideband probe with the AFR trace over rpm. Live while riding as a floating window (Picture in Picture), and in the analysis with map and audio playback. Analysis • Power, torque, rpm and speed as curves, peak values at a glance • Trim the run at the markers, remove outliers, smoothing in three levels or, in expert mode, as a freely combinable chain • Correction to DIN 70020 or SAE with temperature, pressure and humidity, fetched from the weather service on request • Compare runs, with a mean curve over several runs • Vehicles with gearbox, ratios, tyres, weight and driving resistances. Over 100 templates from the Vespa smallframe to the motorcycle Cloud and browser • Sign in with Apple, Google or e-mail and your recordings, results and vehicles stay in sync across your devices • Web app at app.microdyno.de: open, trim and analyse recordings in the browser, download the files • Without signing in, everything stays on the device How it works 1. Create a vehicle or pick a template 2. Mount the phone, connect the sensor or use the microphone 3. Start recording and accelerate through the chosen gear 4. Trim the run, save the result, compare Who it is for Vespa and scooter riders, motorcycle tinkerers, tuners and workshops. Anyone who wants to know what an exhaust, a carburettor setting or a new cylinder really does. Accuracy The calculation is checked against dyno measurements. Repeatable results need equal conditions: same gear, same stretch of road, warm engine. Absolute figures depend on the weight and driving resistances you enter. For before-and-after comparisons on the same vehicle that does not matter. No subscription, no hidden costs. The app is under continuous development. Questions and requests to stefan@microdyno.de.
