So to follow up. I had my cam gears replaced a week or so ago but still had the CEL. I tried flashing b01c again and leaving the battery off for about 15min. The CEL came back.

I swapped in a new (to me) ECU from a '15 flashed that back to b01c and followed the instructions in this thread. Procedure is as simple as it sounds, I had to do the 30min learning twice though, the first time the car would not even try to start, only one loud click. My jumper wire may not have had a good contact the first time. It is easy though the hardest part of the whole thing is removing the connectors out of the old ECU.

CEL is off now and car is running great! So thank you very much for these instructions they were very helpful and it looks like there are some hardware issues with '12 ecus that do require replacement.
