Calibrate Speed
If your GPS speed is different from your speed sensor, you can calibrate
the speed sensor to offset the difference between the readings. If, for
example, you figure the speed sensor is reading 10 percent faster than
actual speed, you will input (–10) in the calibration window. If it is
reading 10 percent slower, you will input (10).
