tach

[freestyle7783]

Which tach is easier to hook up...
Autometer or
Equis tachs

I find the digital tachs are hard to see in sunlight
Heres the manual that explains the different types of connections.
Direct hookup is best.

That's a good looking tach, and I bet it is accurate and easy to read.....BUT, I'm confused. How do you hook it up to make it read correctly?
Even if the sense wire will trigger off a spark plug wire What setting do you use? The 4 cyl (4stroke) setting would take 2 sparks per rpm, would you run the trigger wire long enough to trigger off BOTH spark plugs?

As Mike said it uses an iductive pick-up placed on either plug wire. Then has a simple procedure to program tach for the number of cylinders. (1-12). Few tachs will do this. Only ones that say DIS compatible. (As far as I know)

Thanks Mike. That will give me a better option for the next machine. The tiny ones work great for hourmeters, but not great as tachs.
Here is a video of one I took for tuning the clutches

That is the one that I have in my Max IV:


I think Lewis is running the same one. I don't remember what setting I used with mine but it did read correctly and it is triggered by the inductive pickup that goes around just one spark plug wire.

I looked into this a bit and decided to go with a Trail Tech unit. I just received it and it has not been installed. I ended up deciding on this unit: Trail Tech 752-2013 Black Vapor Stealth Computer : Amazon.com : Automotive

I managed to get it delivered for just under a hundred dollars. Does tach, vehicle speed, odometer, air temp, engine temp, trip distance and time, overall engine time, etc. Hope it works well.

If you like the Equus 8068 here is the best price I have found. I just got mine.

So the tach should be set as a 2 stroke on some 4 stroke briggs engines.

One more thing, may sound stupid, which cylinder is the #1. Front or back cylinder?

Tiny Tach is one of many different manufacturers that make spark plug wire triggered "Tach w/hour meter combo".
They all work the same way, they sense the pulse to the spark plug. There are usually different settings for 2 stroke (spark on each revolution), and 4 stroke (spark every other revolution), ....BUT, most of our 4 stroke motors still spark on every revoution because they are triggered off the flywheel.
I have been buying these Cabela's: Trail Tech TTO Tach/Hour Meter
and they have a simple one wire hook up.

Looking straight at your recoil it will be the left one.

Thanks to everyone for all the information. I think that will p.m. Tim and see if he sells one.

[Obsessed]

Tiny tach is a good option, plus gives an hour meter for a machine that may not already have one. We use them too.

If you want a real tach (analog) for the 4 stroke twin i think this would work on a briggs

Or this one that uses an inductive pickup
