Data Output
Data output is a RS232/Binary/Packet format. Horsepower, Acceleration, and Speed values are transmitted 25 times per second. Aerodynamic Drag, Frictional Drag and other vehicular parameters are transmitted during power-up or following vehicular calibration. The peak buttons may be used as event markers. DynoLog software may be used to record and analyze the data.
