Review: Just installed and works fine. Tach is accurate. Review: I installed this on 2 motocross bikes to track the engine hours so I can use as a gauge for maintenance. It appears to track accurately. It was easy to install. I just wrapped the wire 5-6 times around the spark plug wire and held it together with the supplied zip ties. I then slid it up the wire far enough so it wouldn't be exposed and couldn't get ripped off. I used 2 zip ties to secure the module to the frame where I could see it. Then cut the remaining wire and used a couple other zip ties to hold it with all the brake cables. Very clean set up. Seems to be made well. We'll see how long it lasts. ## Features - HOUR METER----The total hour reading display range is 0 to 99999H, 0.1H accuracy.Trackong the total working hours on equipment in real time, the timer data is retained automatically when the equipment is turned off, and the next cycle is accumulated directly. - TACHOMETER----Measure the current RPM of the engine.
