Since 1957, AutoMeter has set the standard in performance, accuracy and durability with their legendary Tachometers. The absolute pinnacle of engineering and technology, it’s no wonder AutoMeter can lay claim to more motorsports victories than every other gauge manufacturer combined. The patented air core meter movement, wound in house to exacting standards, can move the needle from 0 - 8,000 rpm in 333 milliseconds. An inaugural inductee to the Hot Rod Speed Parts Hall of Fame, no other tachometer on the market has had anything approaching its impact on professional racing. Built for a lifetime of service under the harshest conditions, this is the no compromise tach for no compromise builds. When you’re ready for the best, there isn’t another choice.

why does my tach flutter periodically talked to one tech said put 10,000 OHM in the wiringHi Morton, thank you so much for contacting us. There could be a number of reasons for a flutter, but the most common one is electrical noise. This can be caused by things like poor grounds, inadequate shielding on ignition components or even just a hot rodded ignition system or module. It's very similar to hearing an alternator whine through a radio. Because we've engineered our tachs to be hyper responsive and quick reacting, they have the capability of picking up that electrical noise or interference when it's present in your vehicle's electrical system. Adding a 10k resistor to the signal wire is an easy, inexpensive way to quiet down some of that noise without adding enough resistance to negatively affect the real world performance of the tach. You can see an example of this here: https://www.youtube.com/watch?v=-6j3glUtecY In some instances, really noisy ignition systems (aircooled VW's with hot rod ignitions are infamous for this) may need a bit more than just some resistance. For those instances, we offer a tach filter that does a great job: https://www.autometer.com/tach-filter.html Hope this helps!Date published: 2018-05-17
