you'r ignition timing curve has a couple drops, the car isn't liking it.
what is your Open Fuel Loop setting set at? the OL setting is either set too low, or you don't have enough E85 or enough octane for the boost levels.
For comparison, here is what a healthy timing curve looks like:
E90 LCI M3 7-DCT Interlagos Blue/Novillo Silver
