Yea lots of articles. It's a great thing for high compression or boosted engines.
For the most part E-85 is extremely inconistant on the blend. If you notice, the mixture percent listed at the pump has a wide range. So tuning might be an issue.
If it's an engine with a good engine management system it's a lot easier.
I intend to run it in my boat and also the blown street machine soon. I will just keep some straight ethanol in the shop so I can tweak the mixture as needed.
