Diagnostic tach and mixture gauge

[6T9QDA]

What do you like for an under-hood tuning tach? I haven't bought one in a long time, and apparently they ain't the three-wire meters no more. Can the new laser ones be placed so that you can see them while you have both hands turning screws?

I'd also like suggestions for a A/F ratio meter for temporary use. Thank you.

I use this adapter with my fluke 88. Clamps on to the #1 spark plug wire for tach readings.

I also use a wide band A/F gauge.....An in dash unit, but I use it as a portable if need be. O2 bung welded into the down pipe for the sensor.

I have a bunch of old school one calibrated if needed.

I have a search set on old-school diagnostic tools on Offer-Up but I'm sure you can do the same with Craigslist/Facebook MP/Ebay. I picked up a couple of units for about 10 bucks each. One is really big and you need to set it down on a table or something to work but I like it because the gauge is really big so I can read it from a distance. The other is a small portable unit that I keep in the trunk in case I ever need it but I have only used it once to compare readings with the big unit and confirmed that they worked.

I use my timing light. It has an accurate tach on it.

Big question is it accurate? Thats where I come in.

Fair enough, I can't be sure 100% how accurate they are. I mainly use them for setting idle rpm for a basic tune up and not much else so +/- 50rpm isn't going to kill me. For what it's worth, right out the box both meters have always read exactly the same
Better than nothing...

The Craftsman engine analyzer kit hasn't done me wrong yet. Plus I kind of enjoy how it's a bit vintage.

Mine came with a timing light and remote starter as well.

I got that same unit. It's my "big" analyzer
