Speedo Recalibrating for Different Wheel Size

Is it possible to code the speedometer through Bimmercode if someone goes from 18" wheels to 19" or 20" so it reflects the proper speed?

On x2 there is a secret menu. Hold down your trip reset button for about 10 seconds. A menu comes up. Each reset button hit scrolls, long press selects.
At the bottom there is a secret menu option with password. Password is last 5 of your vin added together, mine was 20 for example. Each press adds a number.
In the secret menu there are multiple choices including temperatures and a correction option, not sure if it’s speed or what, didn’t go in there.

As far as I know, you can't. The speedometer is factory set and can't be altered. The proper way to up size wheel rim height is to get the proper
wheel size so the speedometer indicates the proper speed without any alterations. Therefore the proper height to width tire ratio.

Use the https://tiresize.com/calculator/ and input your current tire size. Then press calculate button and scroll over to the alternate tire sizes column. Then select the 19" or 20" tabs to see the highlighted link for next equivalent tire size. For example, oem 225/50/18 would give you 225/45/19 or 225/40/20 tires.
Remember the rim offset is important when choosing rim size as well
