How to fix a bad tachometer (for your car)

There’s no denying that tachometers are a pain to fix, but there are a few tricks that can help your car to perform more effectively in the future.

Here’s what you need to know about tachimeter calibration.


When calibrating your tach, you should first test for the driver’s position and then check for any irregularities.

This can be done by holding down the accelerator and steering wheel simultaneously for a short period of time.

This should result in a slight change in the position of the car’s tachimeter.


Once your tahometer calibration is correct, the next step is to test your car for the exact same issue.

This is done by placing a hand-held car tach meter in your car’s parking space, as shown above.

Once calibrated, the meter should register an exact reading of 1,000.


Finally, the calibration procedure is repeated for each of your three steering wheels, and the readings are then averaged.

In this example, the tach meters on the front, center and rear wheels were calibrated to be within 1,200.

In the future, we’ll cover more advanced tach calibration techniques and techniques for tuning your car.


When calibration is complete, your car should look exactly the same as when you had your last test.

This means you should be able to test the calibration without any further adjustments.


When your car is calibrated, you can now calibrate the tahometers on any of your vehicles other tachimeters.

This will allow you to easily adjust the position and/or frequency of the tak meter on any other vehicle’s tahmeter.


Finally and most importantly, your tascaler can now also be used on the dash of your car and monitor the temperature in the vehicle.

It will even show you how much it has cooled down!
