Correcting speedo error
 

Does anyone have a topic link or instructions how to adjust speedo error to match gps.
Is it a cog change in gearbox or electronic programming?

If cog change what are Toyota part numbers please or subaru?

Thanks.

I don't actually know but if i had to guess i would say its electronic and a software alteration would be required.


Google speedo calibration Victoria and ill bet you will see some people you could talk to.
