Hopefully, this corrects itself because the chip is working as it should with the factory RaceChip tune settings S1=B S2=1. I wonder what could be causing this. The CEL did not come up when I drove the first 20 minutes I got it installed.

You should install the dummy plug included in the kit and drive the car for about 30 miles. This will clear the DTC through the BMW process which is better than clearing it with a reader. If it reappears on the same setting (I have a feeling it will), you should call RaceChip for their recommendation on a new setting. If it continues to happen, then you will need to set the chip to it's default (explained on page 10 of the manual) to see if it throws a code again. If it doesn't, then start working up from there.
