on my vr2 if i scroll through configuration menu it does not go to wheel circumference setting at all. according to manual it should be straight after rpm settings but mine seems to skip this part of the setup! anyone had a similar problem?

It depends which version of the software you are running.

On mine, the wheel circumference setting is on the Config menu, about 6th line down "Wheel / Weight / Launch"

Try going to the Veypor website to download the latest software update.

thanks mike. i will have a look now! i need it to caliberate speedo as its miles out

I found the best way to do it was to input the wheel diameter (in 10ths of an inch) and then have a run out with a sat nav fitted along side the VR2. Compare the two. Then adjust the value up or down so it's accurate.

Mine now reads dead on.

Don't forget that you'll have to re-do the gear indicator ratio's afterwards too.

Cheers

have measured wheel circumferance on a 205/50/15 toyo r888 to 1800 mm but cant access the menu page to install readings. a bit of a pain really
