If someone could post a model of analog dwell meter that they have gotten to work on a 911 and where to buy it, I think that would be most beneficial (I did a search on our host's site and didn't see one).
I know that all dwell meters are not created equal, and in my case the "Actron" brand meter I have doesn't work properly - reads waaaay too low (and this is the one you will probably find if you walk into any autozone or probably many other FLAPS). I've also read (somewhere here) that you need to use a "powered" meter to get accurate results, but my 60's Sears model that is battery powered yielded similar results. Interestingly, both work perfectly fine on my CIS-equipped '84 VW GTI.
I guess it *could* be the test connector on my car, but the oscilloscope nails it through cold start enrichment, open and closed loop operation on the same wire.
