wear or any other factor that may affect the accuracy of your vehicle’s speedometer. It is important to note

that this adjustment only affects the ScanGauge’s indicated speed and distances, and it does not affect

the vehicle speedometer or odometer readings.

While viewing the SPEED Screen, the lower left and right function buttons can be used to increase or

decrease the selected adjustment in 1% steps.

The upper line displays the word SPEED and a percentage. The percentage is the adjustment factor. The

lower line displays 2 numbers: the left number is the speed reported by the vehicle and the number on the

right is the speed that will be shown by the ScanGauge after applying the correction factor.

One accurate way to set the speed is to use a GPS. With one person driving, the other person observes

the speed on the GPS and adjusts the percentage until the lower right number agrees with the speed the

GPS indicates.

IMPORTANT: OBSERVE ALL SPEED LIMITS AND DRIVE SAFELY WHILE MAKING

THESE ADJUSTMENTS. THE DRIVER MUST NOT BE DISTRACTED BY TRYING TO

MAKE THESE ADJUSTMENTS WHILE DRIVING.

Set the Fuel Cutoff Level

Some vehicles will turn the fuel injectors off while

coasting – this is known as Fuel Cutoff. ScanGauge

attempts to detect the fuel cutoff condition by

comparing the open/closed loop indicator and the

throttle position. If ScanGauge improperly detects fuel cutoff, then you may see fuel economy being

reported as 9999 MPG or 0.00 LHK.

The CUTOFF parameter allows you to set the point at which ScanGauge can determine the throttle is

closed and in the fuel cutoff condition. The default value of 24 is usually correct for most vehicles but may

need to be adjusted. This setting is not critical but is best at about 4 above the no-throttle TPS value. You

can choose to disable the fuel cutoff sensing feature of the ScanGauge by setting the value of CUTOFF

to 0.

Set PID Method

Use the PIDS menus to set the method ScanGauge

uses to store Parameter Identifications Descriptors

(PIDs) codes.

Most vehicles use ALL, which is the factory default. But some vehicles will not work properly unless

SUPPORTED is used. This is the case for 1995 to 1999 Subaru vehicles. If the ScanGauge connects but

then goes to sleep after showing little or no data on the GAUGE display, change this to SUPPORTED.
