E85 + Winter (what should I be worried about)
Well im new to the E85 world and I will be driving my evo this winter. Is there anything I should be worried about or watch for while running E85 this winter or should I just get a pump gas tune? Im open to suggestions.
Thanks,
Brian

Inside but i work into the night so it gets cold outside. I figured it would just have to warm up a lot longer hahaha but for the most part it sits in my garage

Will I have a problem with the 2150s starting the car in the winter with E85?
I have the same concern, but have added large 2150 injectors on a new build, AEM series 2. I just recently found out that you can wash out the rings from repeatedly starting it.
I just stopped driving it until I get this figured out!
Thanks!

It is absolutely all down to the tune. I was the first person my tuner converted to e85 a few years ago and living in Massachusetts we had some fun playing around with the startup tables so she would fire right up in below freezing temps.
Now I have no worries starting my car at any temperature. Last winter, one night leaving work it was about 5 degrees out and she fired right up. Moral of the story-with the right tuner cold startup shouldn't a concern.
However a couple folks also mentioned some things which is worth highlighting again. Depending on what part of the country you live in the ethanol content varies between the months. In MA it typically tests out to around 80% and in the winter months it goes down to about 70%. I test my fuel everytime before I fill up so I am aware of the ethanol content. Typically when it drops to 70% I just go back to 93 but the tune should probably be OK, it'll just run a little richer. So as long as you are cognizant of it and your AFR's you should be OK.

That's great news, sounds like I will be fine when he's done!
Is this the same for either stock or AEM? I am running a series 2 w/gm flex fuel sensor?

What should you do if after testing your e85 it ends up being very low rating, like e50-60 something in that range? Is there any way to easily bump it back up to the correct range?

Benefit of running the AEM v2 with the flex fuel sensor is the ability of the ecu to adjust itself depending on the ethenol content of whatever it is your using. Im still trying to get mine dialed in but slowly and surely its happening.
