Virtual dyno

Upload a log made for the dyno and get power and torque for each run, a quality check of every run, and a comparison with your last saved run. The numbers are estimated from how fast the car gains speed, its weight and its air and rolling resistance.

How to log a dyno run
  1. Only on a closed track or a test day. A run in a high gear to redline reaches very high speeds.
  2. Pick one gear and stay in it: 4th or 5th for most cars (3rd if the car has little power). Higher gears spin less and give smoother curves.
  3. Roll at about 2,000–2,500 rpm, go to full throttle and hold it to redline. Lift, don't shift.
  4. Use a flat stretch. Do two runs in opposite directions on the same stretch if you can, so slope and wind even out.
  5. Log at least: RPM, vehicle speed, gear, accelerator pedal and time. Add ambient pressure and intake air temperature for SAE correction.
  6. Enter the car's weight with driver and fuel. Every 50 kg is about 3% of the power figure.
