Thaught this may be of some interest to peoples with different tyre sizes and incorrect speedo readings.

That's pretty cool! Would need to talk to our resident Jaycar employee though, be damned if I'm paying $50+ bucks for a simple circuit board with no box

Be weird for me too... my speedo has been out for so long know, I'm used to it! At 100kph, its reading exactly 4kph slow. Trials & tribulations of a 235-45 on an 18.

I am the same 3-4 K's out at 100.
But I like that as every 100K's I drive saves me 3-4K's on the odometer, so on the cluster I have only driven 96-97K's .

MIghty Car Mods have also done a video of this If I remember correctly, showing how to set it up etc.
