Re: SE take two! Err, make that three!
 

Safe and consistency are two very different words.

Is E85 safe? Depends.
Is E85 consistent? Definitely not.

The problem isn't the ethanol itself, it's the crap the blenders mix with it to make E85.

Re: SE take two! Err, make that three!
 

Different yes, but they can be directly related for sure.

TRUE E85 is awesome, I agree its the crap that gets mixed in that is the problem. But if you buy real E85, or even C85 (c16/e85 mix) then you have some baller ass stuff.

Obviously many many people run it, especially in evos and for the amount of people that use it there are not a ton of failures, especially considering how hard people push it.

Also, I would imagine texas has a lot more consistent e85 than us MN'ers.

Re: SE take two! Err, make that three!
 

How do I "like" this post? :)

Re: SE take two! Err, make that three!
 

Consider it liked!
C85, E98, or E85 from VP Fuels, for example, is an entirely different animal than pumping it from the corner station. Those have controls and consistent quality, the corner station's E85 does not. I can assure you the ethanol that VP uses is of the utmost quality though, and the denaturant is exactly what you want and where you want it (natural gasoline from Conway, KS blended in at 2.2-2.4%) ;)

E85 down here is a double-edged sword, on one hand we have more consistent ethanol blend percentage, but on the other hand the blendstock seems to be worse quality overall. It's this blendstock that causes injectors to get sludgy, and with unknown blendstock, it is very important to run a tank of quality premium gasoline through the system every few weeks.

Re: SE take two! Err, make that three!
 

You could always buy a 55 gallon drum and blend your own e85

Re: SE take two! Err, make that three!
 

To me that takes out the "convenience" of e85 though which is a huge reason I run it.

If I had to do that I would probably opt for a different form of race gas, be it buying e85/c85/e98 by the barrel or c16/ms109 or vp import or something.

once you graduate to the whole barrel for fueling then it becomes a whole new game in my mind. And also at that point, I'd rather have something that didn't require a HUGE fuel system, so I'd opt for race fuel over e85 variants.

Re: SE take two! Err, make that three!
 

How? Buy a drum of E98? At that point, just run the E98.

Re: SE take two! Err, make that three!
 

Is this toward me? I think I was basically saying this lol.

Re: SE take two! Err, make that three!
 

I say stick to pump gas. E85 is great if you can get real e85 all the time. But with how much money you guys got into your cars I say stick with pump gas.

Re: SE take two! Err, make that three!
 

I love E85 havent had one problem...yet lol. Ron does all my tuning, cant go wrong their. I have a Zeitronix ECA for easy monitoring and evoscan for logging some WOT pulls.

Re: SE take two! Err, make that three!
 

Nope, post above yours.
That's what everyone says until they plug an injector and window the block. Play it safe and run a tank of gas through the system every month. I sell the shit for a living, I'm not making this up.

Re: SE take two! Err, make that three!
 

And if not a tank of pump, at the very least an E85 specific cleaner of some sort. Both Lucas and Gumout sell products designed to clean E85 fuel systems.

When my injectors come out this spring we'll see how well the Lucas offering has been doing.

Re: SE take two! Err, make that three!
 

^Excellent point. Other fuel additives such as Chevon Techron are also supposed to be compatible with ethanol. The problem is there are just no standards or requirements for E85 like there is pump gasoline.

Re: SE take two! Err, make that three!
 

Hmm, I've gone about 8000 miles on E-fuel since looking at my injectors. Now I am super curious to know what they look like. I'll find out when I swap the heads in a week.

Re: SE take two! Err, make that three!
 

I've asked Ron these same questions about the injectors gumming up and he said hes never seen one do that.

Re: SE take two! Err, make that three!
 

I put 10k miles on my dw1300's, they looked perfect when I pulled them.

I guess all of those miles weren't e85, all but maybe 1000 or 1500 were though.

Re: SE take two! Err, make that three!
 

It all depends on your E85source. The E85 down here is notorious for it; seems hit or miss up there.

Re: SE take two! Err, make that three!
 

Some local's hit with gunk as long as 4-5 years ago now.

http://mitsustyle.com/forums/showthr...ck+gunk&page=4

Re: SE take two! Err, make that three!
 

Could be a higher quality of local fuel? Somehow I doubt that though. I've seen so many images of the gunk that it's just easier for me to be safe than sorry. It's not a myth, that's for damn sure.

Re: SE take two! Err, make that three!
 

Yeah i suppose, maybe later this spring when a few more EF2.5's get tuned and tweaked I'll get a 91 map as well.

Re: SE take two! Err, make that three!
 

All depends on the blender, and what they're currently blending with.

Re: SE take two! Err, make that three!
 

You don't even need a full MAP. Just get your injectors scaled right for 91, then just cruise/idle around town and stay outta boost for 1/2 to 3/4 of a tank (don't fill up all the way in my opinion) and you will be good.

Re: SE take two! Err, make that three!
 

I'm no evo tuner though I wouldnt know where to start. Im just evotooner lol

Re: SE take two! Err, make that three!
 

This statement right here will save you all the hassle of this entire thread. People forget to realize that owning a laptop, Tactrix cable, and some software doesn't make you a tuner just because you read a thread about it online.

Re: SE take two! Err, make that three!
 

I think you meant save not have.

Lots of this on the national scale, people think they can tune.

Which is why I always try to remind people that when I say I am going logging/scaling injectors, I am just logging it and a real tuner is doing the tuning.

Re: SE take two! Err, make that three!
 

^Exactly; logging/tweaking isn't tuning.

Re: SE take two! Err, make that three!
 

Pssh, I don't even tweak, I have Jon VPN in and control my computer for me lol.

I don't wanna f it up, even though I know the basics, not worth a motor.

Re: SE take two! Err, make that three!
 

LOL even better. That's how remote tuning should be done. This nonsense about emailing a log and them sending back an adjusted ROM within 24 hours is total BS. Remote tuning should be scheduled with a specific time slot just like dyno tuning is. I don't get these guys who are "in progress" for 2-3 month stretches when I can drop my car off, grab lunch, then come back and have it ready to rock.

Re: SE take two! Err, make that three!
 

I can tune a Guitar!!!

:aikido:

Re: SE take two! Err, make that three!
 

The only delays with Jon are mechanical. He looks at it and basically says, you have a problem with so and so, then I take forever to fix that.

But yes, the way I am trying to do now is setup a time slot for him to work.

Dyno tuning is nice, but I am a big advocate of street tuning now and touch up on dyno, it just seems to get it dialed in better for true street driving as that is where you are driving the car.

But I digress.

Re: SE take two! Err, make that three!
 

Different strokes for different folks. My car is 100% dyno-tuned and it's been awesome on the street in all weather, temperature, elevation, and climate changes.

Re: SE take two! Err, make that three!
 

Agreed sir

Just to better demonstrate how quickly his 2.3L is able to spool the EF4, here is my car with EF2.5 over-layed vs. his with EF4:

http://accessecu.com/dyno/graph.php?...rgb2=204000000

Re: SE take two! Err, make that three!
 

Hmmm, is this just a break in tune?

I'd expect over 500whp on his setup or damn near. I mean, your car (no offense) hangs with him on the graph for a little bit.

Just seems like a very conservative tune for a much bigger turbo and more displacement.

However, its a great looking graph none the less, looks very fun.

Re: SE take two! Err, make that three!
 

It's not a break-in tune, but it's also not a final tune. The engine is still tight and the fuel & fuel pump were overheating due to being on the dyno all day. It goes back on April 13th for the finishing touches.

P.S. ...and my car is just that fucking awesome :D

Re: SE take two! Err, make that three!
 

Ok, well I can't wait to see it with his final tune then :)

Your car is a very solid pump gas car.

But, I am just surprised on his. The like week I ran pump gas on my EF4 I cracked 500whp on like 24psi. We ran into phantom knock stuff (motor noise) though. But it seemed easy to hit 500whp.

Rock on!

Re: SE take two! Err, make that three!
 

For whatever reason, X's seem to make more power with the larger turbos on pump gas. We've seen the same thing down here locally with Blacks too.

Re: SE take two! Err, make that three!
 

That makes my jeans tight

Re: SE take two! Err, make that three!
 

Indeed, still making 300 lbs of TQ at 8000 RPM is legitimate.
