Cable Driven Speedometer +20% Speedo Correction

Speedometer correction is required for many reasons, with larger tyres being the most common off-road vehicle enhancement requiring one of these units.

Changing your diff ratio also affects the vehicle speedometer causing incorrect speedo readings.

 

Calculating the Ratio

The most accurate way to determine the correction box to suit your vehicle is to use a GPS unit and compare readings to your speedo.

Drive at 60 km/h using the GPS record the speedometer reading. Repeat this step at 80 km/h and 100 km/h.

To calculate the required percentage, use the following equation

GPS Speed divided by Speedometer Reading multiplied by 100 subtract 100 equals Ratio

e.g. GPS reads 60 km/h and the speedometer reads 51km/h. The equation would be 60/51 x 100 - 100 = 17.65

We always recommend having a safety factor, so with the above example we would recommend a +20% unit
