Yes. The ECU commands more fuel as expected (IDC's go up, AFRatioEst changes, etc), but the result doesn't change (WB still reads lean).
I'm severely octane limited on the 91, so I can't really get rid of the knock past a certain airflow due to the lean condition. With E85, I don't necessarily see much knock...but the AFR's climb to around 13:1 which is starting to push my comfort level.
If the IPW goes up and the WB doesn't change or continues to lean out, it sure sounds like your out of fuel. Either pump isn't delivering or the injectors aren't.
I've been assuming the log is from pump gas, what sort of IDC's do you see with E85?
