so just a small recap for my small brain to catch up here.
the narrow band o2s drive to a lamda of 1.00 at all times (afr 14.7 that most of us know and love) regardless of fuel? so if e10 has a stoic afr of 14.1 and i swap to e70 the nb will still drive to a stoic (best burn) for the e70 but display it as 14.7 afr?
