Thanks for the logs, I'm glad we were able to get some data and subjective feedback on the Stg 2+ maps and higher ethanol mix!
I'm really happy with the Zeitronix CANBus ethanol sensor. Pro Tuning Freaks did the MultiMap testing with it and it's recommended right on the BM3 tune notes when you flash.

Rather than being located at the LPFP near the tank, the Zeitronix is placed at roughly the halfway point in the fuel line between the LPFP and the HPFP. Precision Raceworks fuel lines replace the stock fuel lines. I also really like that I have a Zeitronix ethanol gauge on my dash. I always know exactly the ethanol percentage entering the engine. Photos and links are attached.
