DESCRIPTION:

Ideal for vehicles with late model engine swaps and applications where conventional tachometer signals are not available.

Easy to install
I purchased this to get the Chrono Tach working in my 1981 Ford Mustang 03 Cobra swap (4.6L Supercharged) project. The instructions was super easy to follow, install was very simple and I was able to hide it in my glove box for a simple easy installation. A++++ for another fantastic Autometer product.

QUESTIONS:
Will 9117 work with auto meter tachometer 4798 To read 1999 mercury outboard v6 2-stroke? Thanks
This device will not work with Mercury Marine applications. See our Marine line for tachometer options.

I need an adapter that can work for a Harley Davidson dyna s dual fire ignition. I already have a couple tachometers laying around, so if there's a way to make one of them work, that's what I want to do.
We no longer manufacture a Dyna Adapter. Check with Dyna Tech, I believe they make their own adapter for this purpose.

Hi, Does this have a function so it can operate like a nitrous window ?
The only purpose this was designed for is getting a tach signal off of a distributorless ignition system.

I have a Crane Hi6N CDI in my 67 VW. This is triggered by a mag pickup MSD distributor. My tach will not operate with the CDI as is. I'm wondering if the Auto Meter 9117 will cure this issue? My tach is an Auto Meter 9304 5" Monster Tach.
Unfortunately the 9117 tach adapter will not work on this application.

Would part 9117 be needed a a 4 stroke, 2 cylinder ATV? The ATV has a coil for each spark plug. Or would it be the same as Deecee 's question? (1 pulse out of the box.)
Unfortunately this will not work for you. For further assistance please give us a call at 866-248-6356.

We do not have a plug and play option for the 9117 that works with Ford.

Will the 9117 Tach Adapter work with my 2006 Subaru Impreza Outback Sport, EJ253, manual. I have a 12v ignition power wire that comes from the main relay to the coil pack that looks like the wire that needs to be cut.
This will work with your Impreza. The 12 volt power to your coil pack must be diverted through the 9117.
