The reason I ask the question is that I'm on my second speedo cable as the first one snapped and both are/were way out.
How do I know?
I use a speedo app on an old phone and it [the app] appears to be consistent with the flashing road speed checks, so I know I'm okay.
When I'm travelling, say at 25mph, in a 30-zone, the app and road side flashing boards shows 25mph and the speedo shows 20-ish.
Two factors to consider. The Mini is fitted with 12x5in JBW replica Dunlop D1's with wide Yoko A539 tyres and the speedo cable has to negotiate the MED sub-stack filter so doesn't get a straight run to the back of the speedo.
I'm happy with this solution as I know I'm legal and safe, but is there anything I can do to improve the accuracy of the analogue speedo?
Thanks in advance.
Peter
