Speedo Corrector Module for Cars

When you modify your gearbox, diff ratio or change to a large circumference tyre, it will often result in an inaccurate speedometer. This 12V module alters the speedometer signal up or down from 0% to 99% of the original signal. With this improved model, the input setup selection can be automatically selected and it also features an LED indicator to show when the input signal is being received.
