Looking for someone or someplace local, MA with an exhaust analyzer so I can set my CO adjustment. Smells rich but plugs look fine. Tailpipe has soot but not too much. Car is an LH Euro so no 02 feedback.

Thanks.

Most dynos have an AFR sniffer.

Brad - maybe your buddy at Factory Five could steer you to a local source.

I have one, but I am a bit far away.

dyno's have a wideband 02.... I know of a true 3 gas analzyer locally, but its a bit of a commute for you

I used to bother going to local mechanics who have exhaust gas analysers - but they're getting rare, and I found variation between a couple of places. If you do feel compelled to go to one, ask them before you go when it was last re-calibrated.

Now I just use a wideband O2 to set the idle mixture (my S4's are factory non-cat cars with no O2 compensation).
