Yeah on stock pump for sure. But you could drop in a B58 pump and turn things up.

Are you sure that's how it works? Based on all the EWG testing it doesnt matter what the base map is in the slot. If you are on FF MM, it will use the blend factor to adjust timing, fueling, etc, all the way up to full E85. The E30 map is irrelevant when you are running FF.

I've NEVER seen it go higher than the max the e30 map provides..
People think that cause they are all of a sudden seeing more timing that it's adjusting to e85.. the reality is that's the max the e30 map allows if the fuel is 100% perfect etc etc.

I've confirmed this personally based of asking and my own logs.

It does though. This was confirmed with John was doing flex fuel testing. See this thread, page 4: https://f30.bimmerpost.com/forums/sh...1868795&page=4

The bm3 flex blend factor changes fueling and igition timing, among other things, based on E%. It goes above the E30 map in terms of timing targets. Its not just that they CAN reach E30 targets now, the actual targets in the map are higher.

Everything is scaled up automatically like Jeremy wrote above.
