ELING Tachometer RPM Gauge with Hour Meter for Car Truck Boat Yacht 0-8000RPM 85mm with Backlight

The ELING Tachometer RPM Gauge with Hour Meter is a versatile device suitable for use in a variety of vehicles, including cars, trucks, boats, and yachts. With a range of 0-8000RPM and an 85mm size, this tachometer provides accurate RPM readings with a backlight for easy visibility. One of the key takeaways from customer questions and answers is that this tachometer is not resettable, meaning the hour meter cannot be reset. While this may be a drawback for some users who want to track the exact number of hours their engine has been running, it is still a functional and reliable gauge. Customers also asked if this tachometer works with diesel engines, to which the answer is yes. However, it requires adjusting the speed ratio, and the installation instructions should be followed for proper setup. Some users reported that the tachometer showed 6-8rpm when the engine was in idle state, indicating that the speed ratio was correct. Another query addressed using this tachometer with a predator 212cc single-cylinder engine. The response suggested testing the function by attaching a test light to the ignition coil wire and checking if it flashes per RPM. If it does, then using the tachometer with the ignition coil wire wrapped around the signal wire should work. However, one customer mentioned that they were unable to get the tachometer to read accurately for their engine, highlighting a potential issue or limitation of the product. Regarding installation on a 1968 Chevrolet C10 with a 250 inline 6 engine, the customer asked for advice on coil installation and settings. The response suggested using a speed sensor instead of the pulse from the distributor to the coil. However, the customer had not yet attempted this method. Overall, the ELING Tachometer RPM Gauge with Hour Meter seems to be a reliable choice for monitoring RPM in various vehicles. While it may have limitations with certain engine types or configurations, the majority of users found it to be a functional and useful addition to their vehicles.
