Aftermarket tachometer for 3 cylinder?; Want it for testing and timing the engine.

I am hearing that I need to have a specific RPM in order to correctly time my engine. I never really cared about not having a tachometer in my car until now as it isn't like I am racing my Metro. I don't want to spend a lot and was looking at some on the AZ website. This one looked nice http://www.autozone.com/autozone/accessories/1Sunpro-2-5-8-in-8000-RPM-Super-Tach-II-black-face-black-bezel-tachometer/_/N-25x9?itemIdentifier=477562_0_0_ but I notice that it doesn't say anything about a 3 cylinder engine. Are there any good aftermarket tachs that work with a 3 cylinder? I guess worst case you could set it up for 6 cylinder and divide or multiply by 2??? If this would work, would you divide or multiply? I would probably prefer dividing as that would give me 4000 RPM of range since this is an 8000 RPM model. Which is it?

Anyway, you don't have a true rice burner until you install a cheap aftermarket tach and fake chrome exhaust tips! I also need some $15 shiny plastic wheel covers for these 12 inchers!

The nearest HF is about 100 miles from here but I will likely be there in about a month. I have a couple of multimeters and wouldn't mind a tach on my car. Are there any that can work or be adapted to work on a 3 cly that are not super expensive? The prices on tachs are all over. Something in the $30-40 range you be great. Are there any that are standard products at Autozone or O'Reilly as that is what we have?

Equus 6086 I had one in my hatch whenI bought it. Works on 3 cyl.

I did some research and it looks like the Equus 6086 is a good candidate for these engines. I also found some on eBay but they were either horrid and ugly or more expensive. The tach goes for $35 or or a little less most places. I am assuming this isn't a huge deal to hook up. Getting the wiring through the firewall/dash is probably the hardest part. I know the dash on the Metro isn't hard to take apart but I was wondering if anyone had any hints as how is best to do this???

Thanks,

Conor

It's not really cheap, but the Scangauge will give you RPM and so much more than you can imagine.

Yes, I have an OBDI with the California Emissions. I don't think the scan tool would do much good.

Glowshift makes a 2" tach that works great for about $40 + ride. I run one in my street car, and one in the Bonneville car too.

And if you really want the Equus then try Amazon.com: http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=Equus+6086

I see the retail price at about $39.

I'm curious is if I go to autozone and purchase a tach that has a switch on it from 4-6-8 cylinder if I put it on the 4 will it read accurately.
