How it works
Specifications
The Performance Computer measures
the performance of your car by sensing
acceleration forces.
An internal precise digital 2-axis accelerometer tracks
your car’s acceleration, braking, and cornering forces
approximately 200 times each second. A built-in com-
puter continuously analyzes this data and calculates
corrected G-Forces for the G-Meter operation, and speed
and distance data for the Timed Run operation.
Your Performance Computer was developed and tested
extensively, both at drag strips and using our VBOX
professional vehicle testing equipment, the ultra-
precise data acquisition system used by auto makers
BMW, Honda, and AMG Mercedes; race teams Ford
Racing, Roush Industries, Chip Ganassi Racing, and
Renault F1; tire manufacturers Michelin, Bridgestone,
Goodyear, and Kumho; and car testers at Car and Driver
and Automobile Magazines.
The result is the most accurate accelerometer-based
performance computer available. And it’s the first unit
with true one-button operation: Press a single button
for calibration, a single button for G-meter operation,
a single button to start a timed run, and a single but-
ton to review your previous runs.

G-METER OPTION 4: BEST 0 TO 60 RUNS
Press and release the G-METER button as necessary to
select “G-METER OPTION 4.”
This display does not show G-Forces, it only displays
your 10 best 0 to 60 times to date. The display con-
tinuously scrolls through your best 0 to 60 runs.
Showing a #1 best 0 to 60 run of 5.64 seconds.
G-METER OPTION 5: BEST 1/4 MILE RUNS
Press and release the G-METER button as necessary to
select “G-METER OPTION 5.”
This display does not show G-Forces, it only displays
your 10 best 1/4 Mile times to date. The display con-
tinuously scrolls through your best 1/4 Mile runs.
Showing a #1 best 1/4 mile run of
13.26 seconds at 106.3 mph.
