E85 tuning
of all the research and threads I read about tuning with E85, I understand that you have to tune the car to see lower AFR's if I wanna run 14.7 I have to tune to see 9.1 when using e85.
am I misunderstanding this? does it means that on my wideband readout I need to see 9.1 or I need to see 14.7 ?
I did some thinking, and what I am understanding makes no sense to me.
so my thinking came up with this. if I tune the car to read 14.7 AFR on the wideband, the actual AFR that the car will be using is 9.1 AFR while using E85 correct me if I am wrong.
please break it down gentle for me at tele tubby level.
I used e85 before, but becuse of my misunderstanding I was running the wideband at 10.1 afr usng a 50/50 mix of gas and ethanol.
please only educated replies, thank you.

14.7 cause like I was saying. Your lambda is set for gasoline, Im actually running on e85 right now, good stuff, 2 degrees advanced timing and 2.5 degrees in boost. It just reads normally, 14's means Im at stoich point...11-12's means Im hitting boost

50/50 mix of gasoline and e85 = stupidity!
