I am guessing that the software is a "no calibrate needed".
As to improving the part, those of mine that I checked, (about 5 of them),had bad connections at the wire end of the think with no damage or changes to any part of the plastic strip. If USA gas affected the epoxy covering the wire to strip connections, then I guess BMW's blaming it on the gas may be valid, but remember that the key antenna also had a bad contact issue under the epoxy or filler, so maybe it was the USA air that caused that.
I feel that they just had poor design or QC on the contact part of the wires to the strip just like the key antenna. Hopefully the next batch will be more reliable although I just figure they sold out of the latest run.
