Whats the coding for this? Prefer to use Bimmercode Expert vice E-Sys

BC_DIGITAL_V in KOMBI set to not active (For the digital speedo)

Also tried setting BC_V_KORREKTUR to not active and it didn't do anything.

How are you verifying the accuracy of the speedometer before/after making a change?

I coded out the offset and verified speedo accuracy using GPS.

However, one unexpected outcome is that when using cruise control, the indicated speed (both on the speedo and GPS) is always 1mph above the set cruising speed.
So, I would set the speed at 85mph and the speedometer/HU display/GPS indicates 86mph. Tried it at various speeds and for various durations over the course of a trip (ranging from minutes to a couple hours), and the +1mph indicated speed never wavered.

That was enough to send my OCD tendencies into a frenzy, so coded it back to OEM configuration as soon as I arrived at the destination.

What did you use to code the actual physical, analog speedo?
