DynoStar is a unique combination of INS (inertial navigational systems), a high performance GPS receiver and powerful data logging with 3D flexible graphics displays.

DynoStar measures the entire performance of a vehicle continuously from the INS and GPS data, and automatically maps racetrack, road etc, as you drive!

It calculates speed, distance, power, and more against time and road / track position. It can do measurements of power and torque in one gear, or power and speed / time through the gears.

Braking time / distance can also be measured easily. Cornering and handling forces can be measured at the same time.

After analysis vehicle performance data is displayed as a 3D-plot road / track position against time, or full 3D position with altitude! You can "drive" through the test with the animated data display, zoom in on areas to fine-tune your car and driving. All parameters of the graph can be altered and saved with our powerful chart editing tools.

DynoStar generates text and csv (Excel compatible) files, so you can easily read and use the data in other applications.

The high performance custom SirfStar 2 GPS receiver can be used separately with almost any SatNav software. Full GPS data is logged by DynoStar so it can be used by other mapping applications after a test run.

DynoStar can be used as a data logger or power meter without the GPS receiver; DynoStar auto detects the presence of the GPS receiver at power on.

  • Find out what power your car really puts out where it counts!
  • Automatically map race / road, and display speed, power and all logged data against
    track position and time.
  • Tune up your vehicle and driving for any track.
  • Curves, showing on the road BHP in different gears.
  • Before / after tests show if those modifications really are making any difference!
  • 0 - 60, 30 - 50, 50 - 70, quarter mile or any other speed timing
  • 60-0or other braking time / distance.
  • Measure tyre effectiveness and cornering forces.
