First, comparing your Stage 2+ E30 log to mine (our IATs and engine temps are in a similar range), it's interesting that you're hitting 14.0 max timing and I'm 12.5. However, you begin to not meet boost target above 5K RPM and are 5psi below target at redline. That must just be the flow restriction on your F30's turbo & manifold, but it looks like the map is compensating by increasing timing with the lower actual boost levels? IDK.
As for the difference bn Stg 2+ E30 and the Multimap, you hit max timing of 15.5 with a similar deviation in boost target above 5K. With the ethanol sensor and flex blend factor in play with the Multimap, things like STFT's are being managed differently and it looks like you're making more power.
But, how does the Stg 2+ Multimap feel comparing to the Stg 2+ E30 OTS to you?
And, how do both maps feel in general to you above 5k RPM when your actual boost is dropping below target? Quicker to shift at 6K RPM?
Lastly, some guys report that burble settings are lost b/n Map 1 and the other selectable maps, when switching between them. Is that also the case when doing flexfuel, or do burble settings stay intact as ethanol levels and the map scale up and down?
