coil pack or DI seal , most likely coil if your not getting any popping sounds with CEL

Thanks, I've actually read those already. I'm not revving 7800+ though and no funny noises.

I suspect it's more related to fueling simply because I have over 40k miles and this CEL has only come up recently, and the first time was the day after switching to the Stage 2 E85 map. Like I said, I should probably go back to regular fuel to rule that out, but I don't always get a chance to run it that low with my long commute and no E85 near work.
