Thread: Speedo Correction Device

Just checking to see if anyone has used a speedo correction device - box. If so which one did you guys use and did it work properly.

I am looking into trying something out. Will be putting in a JDM speedo that reads 180KMs and I will have the speedo read MPH which is about a 63% correction value.


Thanks for any imput.

Haven't used this on a car, but on a bike. Very well known in the motorcycle world for being the "go-to" for speedometer fixing after messing with gearing. Allows for GPS confirmation and only needs a few wires to hook up.

Is it a digital readout?? If so, Dakota Digital will probably have exactly what you need

Dektoa digital makes one. I can't remember the model number off the top of my head. When I get home I'll take a pic of the one I have.

I found this one
