3x/second update isn't quite good enough for you to get a good reading for the peaks of the O2 sensor readings, unfortunately. And a cheapie analog meter is a low-impedance device, so it will cause problems of its own if used on the O2 sensor signal.
However, there is an output on one of the LH connectors where you can get something like a 0-5 volt signal that you *can* read with a cheapie analog meter. Now, the trick is in remembering which one it is and which terminals in the connector they are. (This is sort of like being dropped into a Dharma & Gregg episode ... Now, just *where* did I put that bottle of Hai Karate!)
What I do remember is that there have been a few discussions on the board in which that connector and the higher-voltage signal were mentioned. I'll take a look in Bentley when I get home.
