Setting Up Your ScanGauge Initial Setup Overview To properly use your ScanGauge, you must first set up the vehicle parameters. Basic setup param- eters include, fuel tank size and units of measure. Advanced parameters are also available and are covered later in this chapter. - Page 13 80.5 gallons, use 80 gallons. It is dangerous to run a vehicle out of fuel and can damage the fuel pump. Do not rely on the fuel gauge or ScanGauge at low fuel levels or low remaining distance or time.

Page 14: Advanced Setup Options
The Advanced Setup Options provide additional setup parameters you can use to adjust the functions and features of the ScanGauge to suit both your vehicle and your preferences. This section provides a brief overview of each of the advanced parameters but may not cover the full scope of the subject the setting applies to. - Page 15 Advanced Setup Parameters Setup Parameter Display Options Description Slow Normal Sets the rate in which ScanGauge Data Update Rate UPDATE RATE Fast reports data. See below. Sets the speed offset to compensate Speed Adjustment SPEED -99% - +99% for inaccurate speed readings. See page 16.
- Page 16 1 second. You may also set the update rate to MAX which allows ScanGauge to update displayed data at the full speed of the buss. If the vehicle reports data 10 times per second, then ScanGauge will update the gauge screen 10 times per second.
- Page 17 ECUs and ScanGauge will stay on and drain the battery. If the ScanGauge does not shut down, you can set the SLEEP EVENT parameter to 0 RPM. This will have the effect of allowing ScanGauge to “sleep” when it sees 0 RPM for a period of 10-15 seconds.
- Page 18 For instance, if you fill up, and the pump said it took 55 Gallons to fill the tank, but the ScanGauge said you only used 50 Gallons, the error would be 10%.
- Page 19 To test which method your vehicle should use, you can simply observe the ScanGauge when you shut off the vehicle. If the ScanGauge backlight shuts off in less than 2 seconds of turning off the vehicle, then you should set the TRIPS parameters to AB While set to the AB method, ScanGauge will automatically track all trips through the TRIP A and TRIP B trip computers.
