Gas station on ValVista and Broadway has E81 at the pump...I believe it is labeled as WGDC % to open Diverter Valve in the XDF. I took it at face value and assume it is an OEM safety measure to protect the turbo.
I will focus on understanding the stock boost control strategy this week and do some testing this weekend. I imagine dialing in the PID will be tedious with 4 minute flashes each revision.
My biggest issues right now are post shift rich AFR (DCT) which I believe is a solved problem I just haven't figured it out on my own yet or found any info on it and the fact that I still see a lot of timing corrections even on E30. Although, after thinking about it a bit I realized that since we only have E54 at the pump in AZ that my E30 mix is significantly lower octane than one made with actual E85 since the gasoline in the flex fuel is likely only 85oct. If my math is right that means my E30 blend is only 96oct whereas if I run straight E54 out of the pump I will be at 100oct. I think I will start running straight E54 from the pump and if I have to lower boost to avoid running out of fuel on stock fuel system it will be worth it to not deal with ignition issues.

I live in a surprise though so after getting home from driving out there to fill up I'd need to fill up again.
Anyone played with the Fuel Start AT (VVT) and Fuel Start MT (VVT) for cold start on ethanol mixes? In the latest repo xdf they are duplicated, but same addresses, and I suspect the(Throttled) versions only are used if valvetronic isn't working, although I did wonder if valvetronic would work if it was very cold. There are other afterstart tables, but hoping just these are necessary.
Back to E30, car is not reliable on E40. Sometimes it would rip but most times it would break up post shift or at high load. Not worth trying any more.
My one big hang up so far has been the fuel scalar table. My STFTs are still very negative. I keep reducing the table but, for example, at 4700rpm and 170 load my STFT is -14%. The scalar table at that point is 1.10. Does it really need to be .96? on E30? That doesn't make sense to me when the stock table is 1.0 at that point.
