Glad you got the alcohol content working. In hindsight, I envy the Coyote Mustangs. Super easy to tune and enable flex fuel operation. Mass air flow makes it easier to tune as well. I should never have gone down the EcoTurd route. They sound lame and have lame automatic transmissions. Not entirely straightforward to tune. I wish I stayed with a V8 and manual transmission. Still kicking myself for ever switching out.
