Tiny Tach is in!

[dunedigger]

There are a couple of studs on the intake that it will reach that are the same size as the factory end on the tiny tack. Mine seamed to reach the second one back better than the front one where the engine ground is.

So everyone is getting the standard Tiny Tach DTL? for around $99

How do you distinguish the old version with the 2.5 second refresh

vs

the new with the .5 second refresh?

Thanks

Ordered mine today

Plan on pulling the intrument cluster for clean up and fresh bulbs so while im in there i will install the tach next to the voltmeter.

was thinking of doing these.. switching all my gauges out for new with a in dash tach its expensive but it will be easy to see at night and looks pretty cool

Whats the source on that cluster set? Looks pretty good but do they come in green?

 

[jdeoliveira74]

they are dakota digital not sure if they come in green!! expensive but functional for sure the big fuel gage moves to a small one and the tach replaces it sweet set up !

I don't mean to knock this tach but I would rather mod the vacuum pump shaft and run a mechanical tach.

Has no one in the past thought of this ?

I run a Vertex Mag with a shaft drive tach on my M1028 that's where the thought came from.

And then there is always the tach stud on the back of the 100A alternators.

The HMMWV has what appears to be a tach drive instead of a vac pump. Do they have tachs?

Another choice is an inductive pickup clamped to the alternator.

There is absolutely no reason to need a dead on , instant response tach in a CUCV.

That fancy dash looks cool, but would the tach work with a diesel?

Neat

It is a tach sensor, but it's just connected to the diagnostic connector for use by the STE/ICE-R equipment. There's no tach in the basic HMMWVs, at least in the first gen ones.

I have a tach gauge and mounting bracket that I got off eBay that's supposed to be for the HMMWV. I don't know which models used it, and I haven't tried installing it yet. For that matter, I don't know where it's supposed to get its rpm signal.

Well I got my tiny tach installed and love it. It was easy and its reading 650 rpm at idle and 2200 at 60 MPH

Hi Guys,

Many thanks for such an informative site. I've been lurking for about a year, grateful for your knowledge and expertise. It has been a source of inspiration and advise!

I will be posting pictures.

I am not a mechanic, so please bear with me on what is likely a very basic question.

I have looked in the TMs (and online) but did not find this info.

Please identify for me, the #1 fuel line so I can install the Tach.

I really like the indash installations. Nice work!

MANY THANKS!

I think you are referring to the injector line for the #1 cylinder (driver's side front). The Tiny Tach sender will probably work if clamped to any injector line, but you might as well follow the directions.

Thanks!!!

 

[paraclete comes]

I may try this out as well looks great and practical

I installed the Tiny Tach about a week ago works great i love it but sometimes in the morning when its cold it will read Lo U does anyone know what that stands for?
Thank you

 

[dunedigger]

It reads lo v for low volts. Mine does the same thing but only when it's cold as you said.

 

[Abbylind]

What he said Mine does the same until it warms up

power option for tiny tach

Nice thread. Just got a tiny tach. Where did you all hook into for power? The battery?
