It is an information gauge. It informs you on how many rpms your engine is going. And if you dont know a rpm is a revolution per minute. So when your engine makes a complete stroke that is a revolution. Knowing your rpms can help in shift times and just being able to know how fast your engine is going.What exactly does a tach do for your car?
