Well MMC are wrong ! you can re-calibrate it using the reset button, there is a thread on here somewhere on how to. Might have been a Gambalunga post.Mine was done by Melvyn.

Check out Gambalunga's post 12/11/2016 it tells you how to re-calibrate the speedo.


it is different on the roadster . The instrument they say can't be recalibrated. It has the famous MMC chip to stop revhang & that is locked. the odometer seems to read fine. As the speedo sits in front of the passenger & under the tonneau cover I fitted a GPS speedo above the wheel. That is pretty accurate & I can see it
