E85 FRS getting harder to start in the cold

This is the 3rd year I've run my 2013 FRS on E85.

I've not had much trouble starting the car in the first 2 years. It generally took about 2-3 tries to start when it's cold.
This year as temperature drops, sometimes I need to crank the car like 10-20 times before it would actually start.
Anyone else had this issue? what did you do to fix it? Should I switch back to gas for a while?

My Mods: UEL header, E85 tune from open flash, coilovers and control arms. No mods have been done since switching to E85

I usually just do a 50/50 split or even a 25/75 split (e85/gas).

This is the way. A blend will get you majority of the benefit of eth and mitigate most of the issues.

Keep in mind, as the battery ages, it loses its some of its cold cranking amps potentially. With that said, I think Weederr's approach is sound.

Who tuned your car for E85? If it is not a custom tune, OF E85 tune is not known for great cold start abilities.

Since it has changed I would try a good battery first as suggested above. From there it it all tune related.

Oh that makes sense then. I know a bunch of people here that would love to get it and it just doesn't exist.

If he can "crank the car like 10-20 times before it would actually start" I would not suspect the battery is the issue..
