KWP/9141 Optimization
The rate at which the display updates for vehicles with the KWP2000 or 9141 protocol may be slower than desired. There is a
configuration setting which may allow the rate to be increased. See the following setting:
KWP/9141 Optimize
Enhanced and Safe mode Gauge Discovery
When UltraGauge is connected to the OBDII connector it begins scanning for the protocol supported. Once found UltraGauge then
discovers the available gauges. There are two discovery modes; Enhanced & Safe. By default Enhanced is selected and recommended.
If during the discovery process, with the ignition in the RUN position, the message “Comm lost, Restarting” is displayed, then press
DOWN when prompted to select Safe mode. UltraGauge will remember the mode selected. Once in Safe mode, the prompt will change
and pressing DOWN will return to Enhanced mode.
Injector Cutoff Detection
During de-acceleration, many vehicle manufacturers will turn off the fuel injectors to save fuel. UltraGauge can detect this and factor it
into the fuel usage calculations. Depending on your driving conditions, this may or may not have a significant effect on mileage results.
By default this feature is disabled. See the section for more information. This feature is not supported on Diesel vehicles
Injector Cutoff
Use in Multiple Vehicles
UltraGauge can be moved from vehicle to vehicle. UltraGauge will scan and detect the protocol of the target vehicle automatically.
UltraGauge accumulates distance and fuel usage data. When UltraGauge is moved to another vehicle the accumulated data will need to
be reset. Also, any unique configuration and calibration may need adjustment. For these reasons, it’s better to leave UltraGauge in one
vehicle.
If you wish to move UltraGauge to another vehicle to use the trouble code functions, this can be done with no regard to configuration or
calibration. The only exceptions are if force protocol has been set or 9141 optimization has been executed. These configuration items
will need to be reset prior to moving to a different vehicle.
If you do wish to move to a new vehicle, reset the device using the restore defaults command:
Menu UltraGauge Setup … Restore ALL defaults.
This command will fully restore the device back to factory settings.
If things go wrong
UltraGauge can be reset and restored to the factory default settings. Should configuration changes result in an undesirable setup or
UltraGauge becomes impaired, please see the “ ” command
Restore ALL Defaults
