Portable vehicle dynamometer using accelerometer, GPS and OBD2.
NO ADS! Turn your Android phone into a portable chassis dynamometer. Unlike most mobile dyno apps, DynoTorque automatically measures coastdown losses and supports both GPS and direct ECU data through OBD2 (with ELM327 chip) Choose automatic measurement for a guided workflow, or manual mode to select acceleration and coastdown sections yourself. Adjustable signal alignment, acceleration offset, and result corrections (including ISO1585, DIN70020 and many others) help refine the calculation. View power and torque curves, compare multiple runs, and inspect charts in fullscreen. Save vehicle profiles and export or import results to track changes over time. Results are estimates influenced by road conditions, sensor quality, and measurement setup. DynoTorque is designed for practical performance comparisons and does not replace a professional dynamometer. Repeatability has been tested, and comparisons with professional measurement equipment showed deviations within 2% under the tested conditions.
