This easy-to-use electronic performance meter can compute: 0-60 MPH acceleration time, 60-0 MPH braking distance, 1/4 mile E.T., 1/4 mile trap speed, horsepower, instantaneous G-force, and continuous G-force.
Suction cup mount attaches to windshield. Velcros hold the performance meter to the mount. The system plugs into the car lighter socket.
A simple test of the unit it to hold it
vertically and see that it measures the Earth's gravity. In one of
the the photos, you can see the meter displaying negative 1.00
G (this is the correct reading due to the orientation of the sensor).
