Default Ethanol and Tuning question

If I am in the wrong section, please excuse.
Has anyone who has a custom tune run into there tune not running the same when you started running E10 Ethanol? Have you done a data log before and after tosse if the O2 sensors saw a difference?
Mine is now running very lean on both banks, and the only thing changed was fuel. And I went from single wire O2's to Heated Denso O2's

E5 or E10 should effect anything big...

Put, if you can, non oxygenated fuel back in the car to isolate the O2's. You might find the sensors are the problem, not the fuel.

What do you have that takes 20 gallons? Must be a truck. I wished my Camaro had a 20 gallon tank.
