A timing multiplier based on ethanol content would be the last little bit to make flex work.Latest update is a torque multiplier for flex fuel. Aka adjustable torque/boost automatically with flex fuel. I guess next good idea is some sort of pure pressure based limiters, we'll see.
Picture/summary of custom features available now:
DSG flashing also is working well.

This software sounds pretty legit.Above update post updated to describe the features a bit more in detail.
Add (or pull) timing based on RPM and airmass (mg/stk). Separately define the weight factor for E content. In the example, it's adding 0* timing at E0-E10, and then by E40 it's adding the full amount of timing as shown in the Timing Correction table.
Final Timing = Base timing + Weight Factor * Timing Correction Value
Multiply torque request value based on E content and engine speed. Can be a value >1.00 to increase torque or <1.00 to decrease torque. Crank up the boost with BT setups with E85 or perhaps pull boost back some for stock fueling setups that would otherwise run out of fuel at high E content levels.
Final Torque Request = Torque Request/Driver Demand * OpenFlex Torque Multiplier
Simple Wastegate (SWG):
Take the overly complex and cumbersome OEM turbine modeling and "flow factors" out of the equation and tune the wastegate feedforward/open loop tables based on PUT_SP and engine speed only. This is basically does the same thing as Eurodyne's well-known "Boss loader" file in terms of boost control. Also, makes it easy to tune alongside with the Torque Multipler to tune the wastegate for different target pressures/torques.
