In the general M3 forum, there was a recent thread suggesting that the M3 fuel tank is slightly larger than in normal 3 series, perhaps by .5 gallons, and BMW didn't bother to recalibrate. I haven't looked it up myself, but others have reported a different part number on RealOEM (aluminum vs steel). If so, this may explain how you can run it to 0 and still not yet have starvation.
