You should see about 9:1 for idle and 7:1 WOT on E85

Time for me to get a WB i guess. That might be what I need to get to the bottom of my issues - what are the recommendations for brands. Also what is needed to log duty cycle?He doesn't have wideband.
From my learning experience with e85 is:
WB O2 and monitoring is crucial(logging is probably a good idea for historical data)
Testing of E85 content is crucial to get the correct data - I now run a flex fuel sensor that adjusts my tune automatically in XFI
Powerlogger of injector duty cycle or similar tool
Fuel lines, larger return is a good option on near stock configuration to about 500hp
After all this I said screw it and XFI fit all my needs for a bit more than investment.
XFI also give me other crucial data points (injector pulse width, base VE tables, and 100s of other items)
There is many more benefits of XFI than just e85 monitoring, but I can sit in my car idling and watch all the stuff
If that is a route you may want to take, reach out to Cal Hartline with Hartline Performance and he answer any questions you may have.
If I keep mu foot in it while it is cutting out, it keeps getting worse and i will even see some knock. When I lift a little 80% WOT it comes back.( I have another run where this is display, I will attach that when I get home). Could the knock be false knock?Judging by your O2's, it may be a little on the rich side. They are around 820's now. Try reducing WOT fuel using the chip parameter to get the O2's into the upper 700's. See if that helps clear it up.
Attached is another run where I stayed in it a bit longer. It does show some knock, but ii wonder if it is false knock.If I keep mu foot in it while it is cutting out, it keeps getting worse and i will even see some knock.
