Tachometer is a meter that measures the number of rotation speed per minute of an engine and plays an important role in maximizing engine performance. When driving on the highway or driving sports at full throttle, it is essential to detect the timing of a shift change and prevent over-rev. It is also important for eco-driving, and that is useful for engine adjustment.
Some people may think, “Since it comes with a genuine meter, does that mean I don’t need a tachometer?” That may be true, but for those who want to know the true engine RPMs and want to keep their engine running smoothly, Defi’s tachometer is an essential item.
Defi’s tachometers differ in the accuracy of indication and the time it takes for the pointer to reach the indicated value (response) compared to genuine and other companies’ tachometers. Defi is unique in that it can respond to engine RPM changes and speed reductions and sync the REV limiter activation speed and tachometer display with full control settings.

As serial communication between in-vehicle control devices progresses, some vehicles are unable to receive rotational speed signals for the tachometer.
For some of these vehicles, it is possible to install a tachometer if the product has an added function for setting the number of cylinders supported (1 cylinder/2 cylinders).
Please check the applicable vehicle search for details before purchasing.
