I'd like to pick up a used dwell meter for more tuning on my MCSS. What brand/model and features should I be hunting for?

Main feature you want is the meter being an analog version. Actron was probably the last company to make analog dwell meters.


SBC powered 1987 Regal with TES headers, ZZ4 intake, ZZ4 PROM chip, mini starter, THM2004R, 2500 stall converter, 2040 cam, CCC system, and 3.73 posi rear.

Personally i would buy an Alltest scanner off ebay and benefit from being able to look at most all the CCC system. Here's a 3250 on Ebay right now for reasonable.

As far as buying a meter i agree an analog would be best for checking the DWELL. But you get what you pay for with meters. For all around use whether home or auto use i find a digital is the better choice. In my shop and in my work van both an analog and digital meter has a home. There are times when I prefer the sweep of the analog and times when the accuracy of the digital is preferred.

Just don't buy a cheap meter, it's a lifetime investment. And learn how to use it. Not sure why but some are afraid of meters, maybe it was from checking a 9 vdc battery on their tongue.

I have a Fox Valley, I got it back in the 70's/80's, still works today. It does need a 9 volt battery from time to time!

The problem with digital meters is that they are buffered and give inaccurate and slow readings when used on CCC systems as a result. Plus with analog you can see the sweep and the mean better than with digital. A scanmaster is a good tool to have too for finding sensor issues. But fuel mixture dwell is best set with analog.

I have used digital and analog they both work fine for setting fuel mixture dwell.

I purchased an Alltest a couple of years ago off of eBay. I'll look into the service manual to see what I need to be checking for figures. Just farting around. I believe the only real tuning I have to do is to the carb now. No experience and cheap so I'd like to learn for myself.

I have both an Alltest and a analog dwell meter, even used both at the same time. The analog dwell meter does respond faster but it is limited to just dwell reading, tach, and volt meter. However, being able to see the sweep gives you a more detailed view of the dwell. To match the sweep of analog with digital you would need to record at least 30 numerical readings not missing any. Then add all the recorded readings together, and divide by n to get a sample mean, or you could just watch the needle. Moreover, the Alltest does have more functions which sllows you to watch sensor outputs which is very handy.
