ELINGTachometer REV RPM Gauge with Hour Meter 8000RPM 85mm with Red Backlight

Not clear (at least to me) that this tach will not work for a gasoline auto engine ,, no provision for tach signal from a distributor or ignition box. This relies on a turning signal from a rotating part.

Tried to get to work for my 3 cyl. Outboard motor, couldn't get it to work after many attempts. Now I have a hole cover in my dashboardNot happy with it.

It looks nice but not good for anything else. The instructions shows no example for gear ratio just a random number which doesn't match anything in the documentation. No way to figure out the correct gear ratio to make it actually work except trying 1-400. Not a good buy for English reading customers

Product does not work. I purchased an Eling Speedometer, tachometer, oil prices ressure gauge, fuel pressure gauge, temp gauge and voltage gauge. The only ones working are the fuel and voltage. I would not recommend this brand to anyone.

I tried to get it to it to work. I tried everything I could but it still would not work.

FOLLOWED DIRECTIONS. READ O, 1000, OR 8000. NOT A HAPPY CAMPER, WASTEDA WHOLE DAY MESSING WITH! SPEND YOUR MONEY ELSEWHERE.

I hate this type of advertizing. Priority #1 How many cylinders will it work correctly with? Unreal this information is located no where here. This absolute stupidity stops me from buying from sellers. I would not recommend this product on the simple basis that the advertisement and even the comments refuse to tell if it works on a single cylinder engine. Sellers that advertise like this sould not get customers!!!
