Here's a couple more logs:

Stg 2+ MultiMap with PTF FlexFuel Sensor and E38-39 fuel: https://www.bootmod3.net/log?id=61ca...729b267c1f56ff
Stg 2+ E30 OTS, E40 fuel (same fuel, just mixed up a tiny bit more), Non-LiveAdjusted: https://www.bootmod3.net/log?id=61ca...729b267c1f5714

There’s a little more timing with the Multimap, as expected, but boost target and actual is lower with the Multimap vs OTS and there’s a lot more throttle angle intervention. Plus, the HPFP angle is less overall with the Multimap, showing less fueling need/producing less power.

I asked Halim if we're able to get Stg 2+ E30 OTS like flat boost target and throttle angle within the Multimap, with additional timing added as we add more ethanol and less timing as we switch to just 93 octane.

Will let you all know what I hear.
