Tuning Your Car: Laser Tachometer

A laser tachometer is used for counting an engine’s revolutions per minute (RPM). A laser tachometer does this accurately and at a distance and can take a precise reading in about one second. There are tachometers that require to be physically in contact with the engine parts to read its revolution speed but this is not so with laser tachometers.

Benefit of Tachometer

The number of revolutions per minute at a certain gear will give you an indication of the car’s performance. Your tachometer will guide you on when to speed shift as each car has a maximum RPM at a certain speed beyond which it would disintegrate.

Laser Tachometer

For vehicles that do not come with a tachometer, a laser tachometer can be bought and installed in a racing gauge pod which can house several  gauges or can be a single just for the tachometer alone. These are readily available and easy to install.

Use of Laser Tachometer

When the tachometer indicates an abnormal RPM count you are able to tune your car engine by making a adjustments on your car carburetor. This task can be done in many ways like

• Checking engine and ignition systems
• Setting the speed idle level
• Adjusting fuel to air mixture ratio
• Setting ignition timing
• Setting spark plugs and distributor point gaps

This improves the performance of all the parts of engine tuning.

A laser tachometer will therefore be a sensor of sorts in monitoring your engine performance and indicating when tuning is required. Knowing the ideal RPM for your car will be important so as to be able to detect abnormal counts.
