e85 and winter weather do not mix

DailyN54 · 12-09-2016, 09:43 AM

I was having a blast running full e85 all summer. Yesterday, the temps dropped to 17F and the car would not start. it would fire up and die out immediately. Luckily I did not miss work and was able to have someone help me push the car into my garage. Is there any mix that can work in the winter or is it just better to stick to pump gas?

Get your tuner to adjust the new cold start tables maybe.

FWIW, I'm on ~E65 and have zero issues down to 32*F so far on the OTS E60 MHD map. It should be getting much colder here in the coming weeks though, so time will tell.

32 and 17 is a huge difference when it comes to E85. You can make some tune adjustments to help it out, but its always going to be a bitch

Agreed, hence my "FWIW"; just adding a data point for future readers of this thread

Mine will usually fire up on the third try with E40 and MHD OTS E40map

There's a point of rapidly diminishing return when it goes from cold to COLD...but check out the latest cold start tables in the updated XDF. They work great!

V8bait · 12-09-2016, 01:09 PM

You need to do a custom tune to make use of the new tables, this is fixed for all practical purposes within the limits of the fuel.

bmwmike89 · 12-12-2016, 07:35 AM

Switch to 93 for winter, no point in running e85 during those months.

csu87 · 12-12-2016, 11:23 AM

MHD or JB4?

There is an e85 cold start fix on the JB4. Havent had any issues since loading it up.

b1mmr · 12-12-2016, 06:41 PM

Ran e40 in less than freezing with no issues.. You could tell it started with a little struggle but not to a measurable amount.. The kind of thing where you just know how your car reacts on a day to day basis to everything

DailyN54 · 12-13-2016, 12:46 AM

I was able to pull the car in the garage and put a space heater on to warm up the room. I got the car started and added 93oct. Dropped the content down to E30. No problems starting up now. Car runs great.

Riceball777 · 12-13-2016, 04:48 AM

anything above e60 really sucks when it come to cold starts when its under 40 degrees.

You're joking, right?

The Fuel (Start) table I added fixes this issue 100%.

MHD should make you a deal so it can be incorporated in the app and as easy to set as the burble option (without negative effects lol)

No this should definitely not be a flash option. This should be tuned like any other table and modifed to reflect the tune, be it pump, E30, E50 or E85. It's not just for cold starts that's just where you need it most with ethanol fuels.

You guys don't even know what winter is in Australia. E85 in -20 to 10 degree winters lots of us in the US have to deal with ain't happening. Especially in places where they keep high concentrations of ethanol in the gas year round.

I understand your point. However it's such a great fix that would be enough for me personally to use just for cold starts if possible given you can adjust for E-mix (E85, E50...). Something for the masses and not the 0,1% who can do this in their sleep already.

Agreed; no slider necessary. If the current OTS maps were updated with the proper table edits, that would be peachy keen

I just decided to stay with pump gas.

A. Less power and safer
B. Octane isn't all that good during winter months
C. Alot more traction as it has less power
D. Cold starts don't suck

With that list of excuses, might as well trade it in for 328 instead

Poldav6 · 12-14-2016, 04:58 PM

Do you know how long the E85 stays good? I have had my car in a shop for 10 weeks now, with E60 in my tank. As winter is coming, one thing is starting the car but.. what about its quality. Does it deteriorate? Can it damage something after several weeks?
