M235i Active Sound / Tachometer Sync
I've noticed that the tachometer doesn't seem to be in sync with the piped in engine noise. At lower speeds the sound appears to be behind the actual engine revs. When I accelerate and the tachometer upshifts, the sound lags a second or two behind. I think the tachometer is accurate because it seems to be in sync with the engine as far as I can tell, which would mean the piped in noise is the issue. Is anyone else noticing this or is my car just problematic?
