3.75'' 12V Automotive Replacement Tachometers 0-8000RPM Blue Light, RPM Tachometer for 1-8 Cylinder Gasoline Vehicles, 1-2 Cylinder New Motorcycles

Works great! Instructions are incorrect though. They say to hold set 2 button for 6 seconds to set cylinders. Actually you hold it for 2 seconds then push it to cycle through the number of cylinders.

1st Follow instructions, never worked. humm Got another one, same, same instructions follow to the letter. piece of junk. Looks good, but worthless. don't waste your time and life on this one.. And Yes, I am electrical tech...

Tachometer works as expected, easy to program and retains programming after power off. Easy to set shift light trigger. Nice inexpensive tach that works, can't ask for more.

I bought these to make it easier to tune my carburetor by having a tach visible from the engine compartment. I connected it in-line with the signal wire for my primary Autometer brand tachometer so they both provided a readout at the same time. I found this tach read 100 RPM lower. All of the features that came with it worked fine.

I have had no issues with this tachometer. It was easy to connect, and you can even change the color background.

Works as a tach, but feels very ebayish and cheap. It is definitely not something that will impress.

Works great.. nice tach

Bought this one in a bind till my gauges come in.. the needle isn't accurate it jumps through out the rpm range it's never steady. Don't waste your money like me

This item arrived at my door incredibly quick, the gauge looks great, perfect size, and great price. The biggest issue is it has the worst installation instructions I've ever seen. It was pretty much just a tiny paper with one simple drawing on it, and it mentions nothing about how to select how many cylinders. After days of guessing, and searching the internet on how some other brands do it I found some ideas. It now reads much closer, but still not correct. It looks great, it was cheap, and works better than having NO tach at all. Good for a cheap build but NOT accurate enough if you want something nice.

Worked for about two hours and stopped. Surprisingly low quality.

Looks great, not installed

While you can find guidance in the questions for wiring, it really should be included with the unit. The unit itself is just a stepper motor driven needle, so it's not a true analog, fluid needle. It's very jerky, and I find it to read 100-200 RPM lower than it should. Like another person mentioned, it's better than no tach at all.

Looks good
