My E90 could be coded to show a "true speed" indicator digitally on the cluster. On my 1998 E39 I had to use the OBC average speed indicator - reset it and the first speed that pops up was "true".
Note that the odometer is correct. If you find a "measured mile" or "measured kilometer" on a local highway, you'll find your odometer counts the distance correctly but the speedo reads low if you add a stopwatch into the experiment.

That can be coded but it apparently doesn't work. At least it doesn't work on either of our 535i's.
