I recently made the switch to e85 on my evo 8 this summer and it has been glorious! Boost for days! However as the weather is getting colder, I have been having trouble starting the car when it's cold. This morning was about 36 out when I was leaving for work and it was not a happy camper. I've adjusted the IPW adder table so when the car is cranking at cold temps, it dumps more fuel and I get combustion. The problem is that as soon as I stop cranking, the car pretty much dies. After 2 or 3 tries it kind of runs, but sounds like a subaru. Usually I can keep trying and it eventually runs right and I let it warm up. This morning it just wasn't having it, so I took my truck to work.

Are others having this issue? Is there something else in the tune I can adjust so that it starts up better in the cold? I plan to store the car for the winter pretty soon anyway, but I plan to drive it for a few more weeks at least.

Thanks!!

 

Review these threads if you havent already. There are some good tips & tables to follow / try

Thanks for the links! The second one is tuning via AEM, so that won't do me much good. The first link I've looked at before and is what lead me to changing my IPW values. However, I think this only affects while cranking. I need to figure out what other table I need to adjust so that the enrichment doesn't change so drastically once I stop cranking.

 

what you want is the post primer enrich and post primer enrich decay tables

 

not much u can do just a side effect of #e85lyf

 

good links. thanks

 

E-85 is hard to light off when cold. If you are getting it to fire you are pretty close but it needs more air. Adjusting the idle air table duty up and/or target cold idle will make more of a difference.

 

Or just pedal it

 

E85 can certainly be a b*tch to start when its cold out, especially if you park outside. This is why most winter blends are E70ish.

 

its always hard to start when cold.
i am fine with it. i just keep it cracking it!

 

just switched to 100% e85 and my car never starts on 1st fire

 

Keep throwing more fuel in cranking table? I am having to try 3-4 times when 35F or less.

 

I found some enrichment tables a while back that helped me.

Mine fires first time, everytime, tested down to 10 degrees or so.

 

this thread should help you, alot.

Kind of the nature of the beast with e85 and big injectors. It’s possible to get it right but many e85 cars (including my own) take a few tries to fire.
