In Reply To	using the O2 sensor to determine Eth content rather than posted by LJZTT on June 08, 2018 at 11:28 AM
Message	is if you are continually adjusting fuel mixture, timing and boost based on O2 sensors and knock. The ethanol content percentage isn't really relevant if using the proper hardware, software, and programing. You can bypass a lot of steps and go straight to adjusting fuel supply, timing and boost in real time, many times a second.
