tiny-tach or autometer?

I have their timing light...way better than the snapper adapter
 
I have used both thier original Tinytach non lit and now thier new back lit with recall and I like it

My thinking was how accurrate can an inducer run off the alternator really be because it depends on how good the external tach used for setup was

Tiny tach runs off the injector line pulses
 
I had the older tiny tach on my First Gen. I liked it alot. Install was easy. It was accurate and responded quickly. Worked for what I used it for. (Daily Driving/Towing)
 
What about the digital ones that look like autometer's big shift light them are led numerical and lit up red around the numbers? I got to ride in Craig Severson's pulling truck at SDX a few years ago but can't remember what brand it was? He had it mounted of the side of his a-pillar pod.

i think i know what your talking about

im with you all i dont like the idea of a tach that runs off the alt, and im running a second gen alt, and have it controled off a old chrysler regulator, so the voltage is not constant........


where would be a good place to mount the tiny tach?
 
i had the 2 1/4 (or 2 5/8?) autometer tach that read off the alt and it was ok slightly off, now i run the 5" autometer tach and it reads off my balancer and is dead on.
 
My alternator tach is perfectly accurate. I dialed it in with a photo tachometer and it's balls on from idle to high idle at least.

However, recently it started acting up after five years. It used to be perfectly smooth, now it's kind of sticky after 2000 RPM, but only if the alternator is on. If the alternator is off, it's smooth still. And when I turn on my 120 volt water injection it likes to get jumpy, although my digital temperature controllers both wig out due to the interference as well.

The alternator probes pick up variations in voltage (or something like that), so they should work no matter what alternator you're running. Mine works whether or not my alternator is producing any voltage at all (which struck me as weird).

The problem with the tiny tach as I see it, is that it's not a gauge face. I want a gauge face for RPM. A nice, large gauge face.
 
I had two tiny tachs 7-8 yrs ago, and they didn't respond quickly at all. Or maybe it was just the IDI Fords they were hooked to.???? LOL They were nice at steady RPM.

Have they got something New and Improved? I may look into them again for the 1st gen.

How did you setup your Autometer tach?

Im thinking of swapping all my conversion underneath a early ford truck body and i'd like to go with a full autometer dash, but the tach is hanging me up.
 
i would also like to know this how did you get teh 5 inch autometer tach to work it has a power ,ground ,and green wire for the pickup but how do you get it to work off of the balancer any input would be greatly appreciated
 
I would be interested in using a TinyTach's injection-line pick-up to trigger a standard square-wave tachometer...

Somebody said that TinyTach makes a timing light? Rip the timing light apart and have it trigger a transistor instead of a flash bulb perhaps?

It seems like it would be a more elegant of a way to get a 5 volt square wave than a magnet glued onto the harmonic balancer. It'd only be a step farther to have a magnet on the balancer and a pick-up on the injection line, so that I could keep track of dynamic timing advance.

this is the bracket i built for it to read off the balancer bolts.

i did have to swap to electric fans for it to work.
