My UltraGauge monitor lost many of its gauges after the MB Approved Emission Modification. I did like the UltraGauge when it was working, but UltraGauge support is almost nonexistent and there is no current firmware update to fix the issue, so...I jumped over to Linear Logic and got their new ScanGauge III.
NOTE: My 2011 Roadtrek Agile was built on a 2010 Freightliner Sprinter chassis with an OM642 3.0 L 6-cylinder engine. AEM (Approved Emission Modification) was performed at the MB dealership, and a new updated ECU was installed.
