It takes a little tinkering to dial in. It sort of hunt’s around at idle, it is a fine tach, and it’s maxed out at 4000 rpm. Giving a nice sweep for ordinary, less radical engines. I’m pleased and appreciate the versatility and durability of such an affordable unit.

Believe the bad reviews. Looks nice but terrible lag and inaccurate readings. There are no 4,6,8 cylinder configurations typical of tachometers. I wanted a low rpm gauge for my six cylinder but this would max at 2500 rpm’s and fall back. I tried sending back and getting another and had the same issue. Ordered a more expensive one with better reviews and it works great. Would make a great gift for someone you don’t like.

Although this didn't work for my needs, I see no reason why it wouldn't perform properly in an automotive setting.

I was able to set up this unit with relative ease, the programming Isn't as hard to follow as others have made it out to be. However there is an extra menu that can be accessed by holding the button on the back down then powering the unit on there will then be a 3 digit number ranging from 100 to 900 in increments of 100 it seems like the higher you go the lower the ratio inside of the unit. I also added a 220k 1/4 watt resistor to the tach input to reduce the smaller spikes you get from running coil negative eliminating most of the flutter in the gauge. It has some lag, but if your car doesn't have a tach at all and you just want something so you can monitor your rpm going down the highway, then this is the unit for you. I will be uploading a video with more details of the menus and my overall thoughts on my youtube channel ThatBlueBugGuy.

I am a little disappointed in this meter. I gave it a two star rating because the instructions are just bad. Not very helpful at all. Their customer service is really good. They replied right away to me, but it wasn't that helpful. Apparently this tachometer needs to be hooked to a tach signal from an ECU for the most accurate reading. Most aftermarket tachs get the signal from the coil. This one will work connected to the negative side of the coil, but its not accurate. There are two different settings (see my pictures). If you hold the button down for a few seconds it brings up this H setting. If you click the button continuously for a few seconds it brings up the other setting. The instructions don't say anything about this. So I don't really know what either setting does. The instructions also don't go into what to set it to for different applications. Most aftermarket tachs have a switch on the back to go from 4, 6 or 8 cylinders. Mainly 4 stroke motors. This one you have to figure out what works best. And the two star rating applies to customer service in the sense that they don't even know how to set it up. They basically tell you it is trial and error. Because there are so many applications there isn't one particular setting that will work. Its basically trial and error until you find a setting that works for you.

I was very confused with the H setting for the tach, so I hooked the tach upto a function generator to see what changing the H value did to the tach.Here's what I found out:If I set the signal from the generator at25Hz and set the H value in the tach to 1.5, the tach would read 1000 RPM. If I would increase the frequency, the rpms would go up.If I set the generator to 50Hz, and changed the H value to 3.0, the tach would now read 1000 RPM.I found these results to be linear throughout the test.1000 RPM25Hz | H= 1.550Hz | H= 3.0100Hz | H= 6.0150Hz | H= 9.0200Hz | H= 12.0400Hz | H= 24.0800Hz | H= 48.01600Hz | H= 96.03200Hz | H= 192.06000Hz | H=360.0I found my car was outputting a signal of 33Hz for 1000 RPM s, so I set the H to 1.9 and it worked perfectly.I got the signal for the tach from the engine's computer, on a tach output signal wire. I did not connect the signal to the coil. If your vehicle doesn't output a frequency for the RPM signal, or uses something different, like an AC signal, this may not work for you.
