EM - Earlier than 8/29/11

Customers with an UltraGauge EM with a version date earlier than 8/29/11:

The Alarm thresholds for RPM, MPH and KPH can not be set normally.  Please do not change the Minimum alarm value for any of these. If you do, you may restore the values by executing the menu command:

Menu --> Alarms --> Load Default Alarms

The work around for setting the high alarms is to force the value of the gauge to read the value desired and then enter the menu system and set the alarm.  Once Menu is pressed, it locks in the value and will allow that value to be set.  For example, RPM would be set as follows:

1. While in neutral run the engine up to the desired RPM

2. Press Menu

3. release the accelerator and allow the engine to idle

4. Go to the alarm setting for RPM. The only value that can be set is now the value of RPM just prior to pressing MENU.

For MPH or KPH you will need to be driving at the desired speed. This will require a second person as the driver should never use the menu system while driving.

The UltraGauge EM is unable to read trouble codes for Vehicles which use the J1850-VPM protocol.  The J1850-VPM protocol is commonly found in ~pre-2006 GM vehicles and '95-'97 Toyota's and rarely in some pre-2006 Chrysler's.

MENU -> UltraGauge Setup.. --> Version

Minor Bug Fixes include:
  • Gauge Unassign issue
  • Distance Gauges Limit
  • For some vehicles, the Boost Gauge may not factor in ambient pressure - very rare
  • Suspending UG Voltage and/or UG Temperature alarms may Suspend Trouble code and/or Pending Trouble code alarms as well.
  • Gauges with time formats can't handle large negative time well (For example, Time To Empty will go negative if your are beyond the estimated Empty point)

For UltraGauge EM's with a version prior to 2/25/14:
MENU -> UltraGauge Setup.. --> Version :

UG may not be able to read trouble codes on some vehicles. This only affects vehicles which use the CAN protocol and only those that have an internal CAN gateway. We have only seen this on late model (~>2009) foreign vehicles. This is very rare.
