So i've been reading a lot the last few days(IE: neglecting homework!!) and I'm a BIG fan of E85 since I've seen massive gains across the board on all boosted platforms by switching and It's ALL over Colorado. I've noticed that it's not very supported by the Audi community which is understandable since it's more of an inconvenience and most people don't mind the cost of meth on top of 91/93.
Whats it take to run E85 exactly? Is it as simple as compensating for the larger injectors and the 30% more fuel needed? Then obviously tune for more boost/timing depending on the turbo setup? I'm very new to this but i'm also VERY curious. Be gentle  I'm still learning/memorizing the damn Alien text you guys call "code"...

I've read a lot about E85 and cold starts, being in Colorado, it's a big concern of mine. Bluewater Performance here in Denver actually does a flex fuel type setup... any info on this? I'm assuming it's with a flex fuel sensor but how the hell would you tune for something so dynamic? Also, since cold is an issue, is it like diesel where it wont even start at times? When I was hardcore DSM I was in the know but that was almost 3 years ago now... any solutions? How about the gunk on the injector tips issue?

I have read up on it and i'm not any sort of expert but I do know quite a bit about on the topic. Just not sure how it transfers into Audi form. Thanks for what you could contribute though! Maybe I need to figure out the whole bosch tuning idea and then start easing into some E85. It's MUCH MUCH more forgiving when learning to tune mainly due to it's race gas tendencies against knock.

And yes, though it's much more forgiving regarding knock, people new to the fuel tend to go overboard with timing and can more easily make it past MBT.  Once you breach MBT, cylinder pressures go up FAST, so be careful not to blow the engine.
