I got a ultra-lite tach, but when replacing the engine to a modern LS, it doesn’t work. Do I need the 9117 then?Hi Tomas, thank you so much for contacting us. The short answer is maybe. Typically when LS computers are flashed, the tach signal can be degraded or eliminated altogether. Sometimes you can use a pull up resistor to get the signal from the computer to work. We write about it in detail starting on page 7 of this manual: https://www.autometer.com/media/manual/2650-1563.pdf There is always a possibility that the signal is completely gone depending on how the computer was modded. In these instances, the 9117 tach adapter will always get the job done. While it's not a terrible wiring job, if you want to just plug it in and go, you can use this kit which takes no time at all to install and requires no modification to the factory wiring: https://www.autometer.com/ls-plug-play-harness-with-tach-adapter.html Hope this helps!Date published: 2018-07-10
Does the ATM-4497 include the wiring harness as it is not mentioned on the package contents?Hi Roger, no wiring or harness included. Many complete aftermarket harnesses feature the proper connector, like our 2198, but this is designed for an entire set of 6 instruments. Otherwise, the 4497 features 1/4" blade terminals on the back for the connections. We also offer this 8 pin connector, model 3299, to assist in creating a harness: https://www.autometer.com/tach-speedo-connector.htmlDate published: 2018-06-29
What signal does this tachometer require? Would it work with a 12V square wave signal from an aftermarket ECU?Hi Roger, thank you for the question. Yes, 12V square wave is the standard signal that our tachometers will read. Some will even trigger down to a 5V square wave. An aftermarket ECU that is providing a 12V square wave tachometer signal should trigger our tachometer.Date published: 2018-06-29
just wandering can you use a shift light with these in dash tachometers or can it only be used for pedestool onesHi Kev, thank you so much for contacting us. Our in dash tachs typically do not have the ability to control a shift light, and this model is no exception. A really great option for an in dash tach is this Elite model: https://www.autometer.com/3-3-8-tach-10-000-rpm-in-dash-elite.html The entire face of the tach is the shift light and will change color to indicate it's time to shift. Otherwise, with a conventional in dash tach you'd want to use one of our intelligent shift lights. These function independently of a tachometer: https://www.autometer.com/catalogsearch/result/?q=shift-light+level#1&profile=products Hope this helps!Date published: 2018-05-29
