Can a Mk3 Punto speedo be re-calibrated to allow for different sized wheel/tyre combinations? Any tricks anybody knows of or failing that, can a dealer do it?

there is a calc some where will find link. but 17s on a mk2 only make speedo 2mph under iirc at 70 so not worth worring about imo

OK, I'll come clean. The engine and the management are in my classic Panda. All works, but plan to put in vastly smaller wheels than the Punto had. I know how to work out the difference between the wheels in terms of rolling radius or circumference, I just want to tell the ECU the new number. Do-able with plug in diagnostic stuff?
ah best talk to panda-sport, he know a lot about this 
using a tiny digi dash
the punto stores the speedo stuff in the body computer though not ecu

Thanks. Yes, panda-sport and I have spoken quite a bit at events and on the forum, but as he is not using the Punto electronics, I think Mk3 Punto folk are the best people to direct the question to. I am using the full dials, body computer and ECU set up, so it behaves exactly the same as a Punto Mk3 1.4 16V.
we call it a mk2b punto in uk though, may be best to talk to one of the fiat techs like T

2b indeed. Thanks for that. Who is T? A forum user?
yeah T14086 we call him T because we never remember the numbers
