What does the Cutoff function do?
Some vehicles will turn the fuel injectors off when coasting down. We sense this with the open/closed loop indicator and the throttle position. We have to know if the throttle is opened or closed but the minimum value for it is rarely 0. The Cutoff is the value the throttle has to be below in order to indicate a fuel cutoff and show 0 fuel flow.
The default is right for most vehicles, but it can be adjusted for different situations. If set to “0″ it disables this method of fuel cutoff sensing.
Can I purchase an extra cable to use in another vehicle?
You can purchase an extra cable with your ScanGauge II or a single cable at our Purchase Page
Can the ScanGauge show if there is a difference in MPG between using my truck with the tailgate up or down?
Yes, the ScanGauge can show if there is a difference. Read about it here: See Tailgate Up/Down and Gas Mileage.
How can the ScanGauge II do all of these things with only a single connection to the vehicle?
Since 1996, all cars and light trucks sold in the US have been required by law to have an On-Board-Diagnostic version 2 (OBD2 or OBD II) connector inside the passenger compartment. It is required to provide diagnostic information and allow resetting of the CHECK ENGINE light. It also provides a lot of other operating information. The ScanGauge II performs the diagnostics functions like a conventional scan tool. It also goes beyond this and uses the other data to add many more useful functions.
