Would you double check the report's O2 readings for me and list the software version/EIS number (located just above the signature block). My recent test was 0403/ES974825.

It doesn't make sense to have over one percent 02, and unless BAR changed the format on the test report since my 190E 2.6 was tested last March, O2 is reported with two digits to the nearest tenth percent such as 0.2

Is O2 now reported to the nearest hundreth percent? Or is it now PPM?

If the lambda system and catalyst are operating at near maximum efficiency the O2 reading should be no more than 0.1 percent (or 1000 PPM) and preferably 0.0.
