PDI Digital Speedo Corrector

We have updated the speedo corrector that has a LCD display inside showing the ratio thats being used.  Still simple to install, with just 4 wires and only 2 buttons (up and down), now the expected ratio can be input before driving it.

NOTE: Suited to non-CANBUS systems so if there is no speedo sensor on the transfer case then our unit won’t work. ie it won’t work on the newer VDJ79 that take the speedo signal from the ABS wheel sensors.
