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.

Not custom. Off the shelf tune from open flash

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

What those guys said.

I am more curious as to where you find E85 in Ontario?

Battery is brand new, replaced last month

Ahh I'm living in the US now. There are 3 stations within 10 miles of me:)

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

Yeah cause a battery has never been DOA before...
Is there something that says the battery is good?

A test light. :iono:

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

Not at a reasonable price anyways. Buying 5 gallon containers for $120 doesn't make sense.

Yep. The couple of people at work that are looking bought flex fuel vehicles without checking if they could even get the fuel.

I have same problem. Been on straight e85 since last year. Cold starts getting worse and worse . Now if it's below 50 I just use a little ether and it fires first try.

E85 is either E85, or it is sold next to E55, E65 and E75, or it is advertised as E85, but if you look on the pump it says E55-E85 blend, where it will be closer to E55 in cold climates and in the winter, and it will be closer to E85 in warmer parts of the country and in the summer, so LA in the winter might be similar to Maine in the summer.

Besides blending it yourself, you can do a few things:

-Turn the car on to prime the pump for a few seconds before turning on the car.
-Turn the car over, but cut off the process after a few cycles by removing your foot off the clutch, and then push your foot in again fast or try starting the car again. The car should start right up and not crank until it fades or until it barely starts when the CCAs are fading. This process removes some vapor in the system and provides a fresh crank to when the engine has fresh fuel.
