Question regarding COMAND 2.0
I have a W208 CLK with COMAND 2.0; I know if I put on different sized wheels/tires than OEM I can calibrate via COMAND to recognize my new wheel/tire combine diameter and match with the navigation speed and distance traveled with actuals.
Does doing this help the tachometer to compensate for the increased wheel dimensions as well or is that in a separate system?
Thanks!

Not super familiar with the CLK, but most MB's can be told by SDS what size tires/rims are fitted. COMAND does dead reckoning using a gyro and the wheel speed sensors, so the SDS change would be impacting the speed signal. Speed signal is used for miles traveled and speedo, so that's going to keep things accurate. There's a limit to what you can change, and as I recall it's limited to tire/wheel options on the car..
Not sure why your tach (engine speed) would change due to wheel diameter, though..
