I used the search button couldnt find anything convincing. So im wondering still, can i go full E85?

Mods: K&N cai, zzp ic, dejon charge pipes (upper and lower) 3 in catback, catless dp. trifecta tune 23 psi.

What are your thoughts and what would you reccomend.

 

Yes you can but its more difficult to do. But can be done. And it. All depends on ure fuel system, and elevation, mods and.ect. and.of course tune. Get ahold of a good hptuner if you want.to get your tune.done.quickly. I am sure vince can get it straightened out.



Also bro, I recommend e47 just due to it being safer and easier on Ure fueling

 

On an LNF. No..Just No... I dunno talk with someone who has done it. Seems like if you live in a cold state, its not worth it for the direct injections. Takes forever to start-up. Just my BS from seeing other threads and youtube vids of LNF's on E85.

GL if you do. Great gains from it. I plan to go E once motor is fixed.

 

As stated you can but there are limits

 

I hear cold starts are tough but I know a couple guys here in Colorado doing full E on a regular basis. Only to switch to 91 for winter. Even when it's around 40*F he is okay. I think our elevation helps.

 

There's some debate about whether or not the injector o-rings get eaten away by E85, too.

 

The injector seals are a nylon that burn up with a bad ethanol mixture and even a bad tune by letting ovr enriched conditions so therefor it eats it away. But on e47 with the petrol charistics like the lubrication it helps to not cause it. But the issue. Also consist with bad seals already

 

Yes u can go full e85, but in winter up by us its downgraded to 70% or so, so I wouldn't reccomend it in winter unless u re-tune it, I agree that the full extent of using e85 in any vehicle including flexfuel is unknown on how much damage it does long term, I would reccomend using it on a wkend or whenever u plan on racing then switching back, agreed with goin e47 or any grade of e availible in your area

 

anyone havin cold start-up issues is because the e85 for our region is graded down, so they will have to re-tune for whatever percent the winter mixture is

 

I had a full E-85 tune from Vince and it was much faster than the E-47 tune I got as well. My mods were K&N SRI, OTTP charge pipes, and catless downpipe. Only issue with the full E tune was fueling cutting out in 4th at around 6k rpm's at wot. If I asked I'm sure Vince could have lowered the boost in the high rpm's to compensate. Everyone's car is different though. I would give it a shot, and see how you car responds.

 

Only reason your E85 tune was faster than E47 is probably BC the E47 was mildly tuned. There has been some testing done by the member, Iambroke and he found when tuned properly, no gains were had past E47 on the LNF with current available technology or parts (not including zzps cams with bigger fuel lobe). This was due to the midrange fuel requirements. Straight E85 Burns too fast for our system to keep up with.

This has been discussed extensively on this site I'm surprised the OP couldn't find his answer.

 

You can zzp has cams with upgraded fuel lobe for increased fuel

 

i also had fuel cut on e85 trifecta end of 4 gear

 

Lazaro, just with the base file how was fourth. Any issues

 

your tune or trifecta?

 

Mine.

 

No issues, 4 pulls hard

 

pardon my retardness...where can e47 be found is at the pump like e85??

 

no where. you have to blend the gas yourself.

 

whats the blend?

 

I run 5 gal, e85. Then fill up 93 on top of it.
