Coding: what does BC_V_KORREKTUR do on '09 e92 M3?

[hackR]

I know that to correct the digital speedometer on the '09 e92 m3 (once activated) that you set BC_DIGITAL_V_KORREKTUR to nicht_aktiv...

What does BC_V_KORREKTUR set to nicht-aktiv do?...

I set BC_V_KORREKTUR to nicht-active w/o changing BC_DIGITAL_V_KORREKTUR to nicht_aktiv and i didn't see any effect...I read somewhere that you should change both to nicht_aktiv...

Any idea what BC_V_KORREKTUR does?

BC mean's Board computer
nicht aktiv mean's not active ( disabled )
Korrektur mean's correction

That's just the german translation, hope it helped.
Driving 50mph will let your digital speedometer show 47mph.
So no correction will be shown on your digital speedo compared to your analogue.

this is what happens when you set BC_DIGITAL_V_KORREKTUR to nicht_aktiv...

what does the BC_V_KORREKTUR do?

It correct's the digitally shown speed value to the analogue gauge!

really?!...cool...i didn't think the analog guage could be adjusted...

so - by setting both, you are essentially getting the same, CORRECT, speed...

Think it's for adjusting digital to match analog, not the other way around

Unfortunately there is no way to get the analog gauge to read correct digital speed just by setting the BC_V_KORREKTUR

I have set BC_V_KORREKTUR and BC_DIGITAL_V_KORREKTUR both to not active and while the digital gauge now reads right on the analog is still off.

@whatsADSM - that's how i'm seeing it...didn't think you could adjust analog dial - and adjusting BC_V_KORREKTUR to nicht_aktiv doesn't seem to do anything...however, adjusting BC_DIGITAL_V_KORREKTUR to nicht_aktiv shows the real speed (which is lower than the analog speed...ie. digital at 78 - analog 81ish)...
