The following list contains known or potential vehicle's which are not fully OBDII compliant and/or not compatible with UltraGauge. This list applies to all UG with a version prior to version 1.2. Version 1.2 began shipping on 6/27/12 in the US and 7/8/12 internationally.

STATUS
 
Confirmed - UltraGauge.com has confirmed this incompatibility
Unconfirmed - An UltraGauge customer has reported the issue.  The issue may actually be a problem specific to their vehicle and not to all like vehicles. This should be considered a warning and you should be prepared to re-task your UltraGauge to another vehicle if you experience the same problem.  If you can also confirm the problem, we would greatly appreciate it if you could alert support via the support ticket system found here: Support Ticket

 

Any vehicle with a multi-displacement engine that does not have a Mass Air Flow Sensor (MAF) will not measure MPG accurately, unless Multi-displacement is disabled via Auto-Stick or equivalent..  Learn about MAF here

INTERNATIONAL VEHICLES:   It is imperative that a target vehicle is confirmed to be OBDII Compliant. Once confirmed, then this exceptions list can be consulted. Please see the compatibility page for OBDII compliance

Returns received that were purchased for a vehicle on the exceptions list or one that does not have an emission label marked as OBDII certified or compliant, will incur a $15 refurbishment fee
