E85 who's doing it
Just wondering who here is running E85 what mods are you running for your fuel setup? any issues? I'm looking into switching to e85, I have the AEM 340lph fuel pumps which allow for e85, have bigger injectors and looped fuel rail would I need anything else to run e85? Thanks

There are several rational, researched statements to make about its usage in general. The W211 platform has some good positives, but also some negatives that would have to be dealt with.
The fuel rail is SS. This is a great thing. The Fuel system lines have few rubber pieces - this is also good.
Submerged pumps and wires? Something to look at.
Corn juice is too good to not do some work to run it. The safety margin it creates cannot be ignored.

I only know of one person on here who ran E85 for 2 years but he always told me it's not worth it and that I shouldn't waste my time with it and I left it alone, but now it's like well I got pumps to be Able to run E85, I might as well just try it and if it's not to my liking switch back to pump gas and be done. Either way I'd like to get some opinions or for someone to chime in who is running it.

Pumps. Great - find the right ones.
Having enough fuel? Possible as problem. Line size, pumps, etc. variable voltages...
Returnless? Not sure if this a problem.
Just like on any forum, there is some misinformation, and some non-information.
Ethanol does not corrode. The water in it can, but you can account for that. It softens natural rubber. There simply is not any natural rubber in most modern cars.

I only recall hearing that it is not easy. It was debated on here about a year ago but I just don't recall what the issues were. I run it in my Cts V and in that it is only a matter of injectors and tune so it is ridiculously easy in the V but not anything close to as easy in the benz. I can tell you that you pick up an instant 7-10% whp in the V in applications between 500-700whp! I couldn't see why it would be different in the Benz but there were issues!

10% increase in whp !! How could anyone say it's not worth the hassle Just as said above the safety it provides is as invaluable as the power and torque gain it provides. Can someone provide info as to why it's difficult? I've seen alot of cars running it, many different models. What the problem?
....I wouldn't be surprised though, these cars are a PITA to do anything to. Mercedes are degenerate scum, they deliberately make every little damn thing difficult. I would love to kick a Merc executive in the teeth

E85 does change with seasons where it is cold. Very cold weather without the proper stabilizers in the fuel can cause some issues.
It may also be that the code has simply not been cracked enough with the ecu to really dig in and control the starting code. You have to start the car differently with ethanol when it's cold. As in, below like 45degrees.

I've been supporting all of your questions regarding E85 in like 5 different threads. Why was ANOTHER thread needed?
This **** is simple people, read.

lol he must be, since there was 5 threads I've only seen one other where he replied seemed like responses were quicker, I started one since I didn't see any answers anywhere and then another thread popped up with all the answers end of rant
Pumps
Injdctors
And tune is all we need
But I think after all I'm going to stay away from it this is my daily I will be converting my gt500 to E85.

I'm speaking to everyone who's still wondering. The answers have already been stated.
Pumps, injectors, tune. There are only a handful of people on E85. It has a lot of benefits but it is a temperamental fuel and difficult to locate in certain areas. BIP has been able to supply a tune and support the handful of guys that have taken the plunge. The tunes are not perfect, but they're acceptable.
Craig put some good miles on it and I'm 15k+ miles. If this isn't acceptable history on the subject, I don't know what more you guys are looking for.

If you saw another thread with the exact same info, then why did you make another one? That thread was from 2013 and you made this one yesterday... The information was out there, you guys just don't look.

It's easier to find answers when they're all located in one place.

The info is here, but it's sometimes a bit... Measured - in such a way, similar to other info on this forum.
Craig is very helpful. There are clearly some issues to still overcome. 1000cc injectors are quite large. If there is not very good injector control built into the ecu, there will be some loading issues at idle.
Close eye would need to be kept on the etoh ratio.

I ran 725CC DI injectors with my e85 set up to 620 RWHP and they tuned out well. Idle was always smooth.

Still trying to figure out all of the huff and puff over a new thread!
Anyway, Exotic: how much did you gain from it? I thought that no one was getting the tunes all that correct so they weren't gaining much and that was the reason for very few people doing it.
As far as starting in the cold weather with E85...yes, it can be difficult but I think it is ok at 45 degrees. I would say that under 40 it becomes a little longer to start and then temps below that, it gets harder and so on and so forth. I have a flex fuel sensor now so I mix 1 gallon of 93 or so to each 3/4 tank full and starting is a breeze. Without it, getting weak E85 could have hurt the motor (winter mix) which was mentioned above by someone.

Look into Recreational 90 instead
100% gasoline.
Dont waste time, fuel pump, lines, and worse mpgs with e85 crap.
Pure-gas.org for Rec90.

It's too bad somebody doesn't make a kit for our motors. I would love to do this to my car but I don't feel like experimenting ,

Being from Houston, our E85 mixes haven't changed at all even now in December. Most stations are all right around 85%. personal tester confirmed. There are a bunch of stations around Houston. Good town for E85.
EDIT: And if tuned on an Proven 85% blend, and the stations sell a winter blend that goes down to 70%, the worst that happens is you run a little rich. Not a big deal.
So ... bad gas mileage? Rofl. 93 octane is still $3.00/gal. E-85 here is $1.50/gal. Hmmm. Math is easy. logic is easy. 25% loss in gas mileage proven over past 2 cars on E-85. 50% cheaper. STILL 25% better off in cost. AND more power. (observed 10% more power than gas in agreement with statement above) AND safer against detonation, AND more consistent power pull after pull. Specially on a supercharger.
This is kind of a, "no duh" kinda thing for me here in Houston.
