One pull. The graph is brake horsepower against rpm, calculated from the data the vehicle provides. An estimate, not a hub dyno. It uses the ECU’s torque when that is reported.

Use on the road at your own risk

You are responsible for the vehicle, passengers, other road users, and for obeying all traffic laws at all times.

Do not look at the screen while the vehicle is moving. Do not carry out wide-open-throttle pulls, logging, or any test unless the road is legal, clear, and safe, and you can keep full control.

Tests in traffic, near pedestrians, on wet or broken surfaces, or where speed limits or local rules forbid it, are on you — not this app.

Data-drive and its authors accept no responsibility or liability for accident, injury, death, vehicle damage, property damage, fines, lost data, or any other loss arising from use of this software or any OBD adapter, including if a reading is wrong, a feature fails, or the app distracts you. You use Data-drive entirely at your own risk.

I will obey the law. I use Data-drive at my own risk.

Petrol or diesel only matters when the ECU does not report torque.
