Hi all,

Ok, I know about the coding to deactivate the 5-10 mph over actual reading on the speedometer, what I'm asking about is the possibility of a way to compensate for changing the sidewall height of the tires. I have the stock sizes on my '08 E60 M5 now (285/35-19), but will be changing to 305/30-19s on the rear and 275/35-19s on the front. I know this will cause the speedometer to read low, but not sure exactly how low. I'm hoping that perhaps just re-enabling the BC_DIGITAL_V_KORRECTUR would match the error in the reading, but won't be holding my breath. So if there's a way to code in an exact correction for the speedo, I'd love to know how to do it.

Anyone?

Thanks,

Peter
