Maybe a problem ?the spark plugs aren't wet either . The entire fuel system is new . Every piece . Could the e85 have swelled the injectors causing them not to work ?? Also might have another problem . My arc2 isn't lighting up when I turn the lights on.
Do you have a data logger?
How did you plan to tune your engine for E85?
What fuel pressure regulator are you using?
I would start with trouble shooting the ARC2. I would start here.
