9. The accelerometer needs to be mounted solid and level. Vibrations in the mount will produce noise in the readings.

The accelerometer is designed to be mounted solid to the chassis or affixed to the roll cage. Typically a bracket such as this is fabricated to mount the unit on the bar behind the driver seat. Auto Meter points out that if the mount is not strong enough to prevent flexing, then the accelerometer will see vibrations and can provide distorted acceleration readings. There's more too: The accelerometer must be mounted so that the face is directed toward the front of the vehicle. The unit must also be mounted perpendicular and level to the ground. There should be sufficient room in the mount so that the accelerometer can rotate 180 degrees in the brackets for calibration. After the accelerometer has been mounted, simply plug the connector into the ACC port on the rear of the computer.

10. Installation in a magneto-fired application requires a shielding enclosure for the computer. Some applications may require shielding at the pressure sensor as well. These enclosures need to be constructed of steel material. Aluminum or stainless steel do not provide sufficient absorption of EMI radiation.

For a closer look at the installation process, have a peek at the accompanying pictures. Much of the work is simple, but remember, there's definitely a right and wrong way to install sophisticated electronic hardware.
