Why arent you using E85 / BioEthanol ?
#63
That's why at the moment this thread was about using a mix of e85 within the tank along with petrol. Something like 10% e85 seems to work very well and is easy to do. Simply carry a 5 litre can of e85 and put that in the tank when you fill up (45 litres of petrol)
With a 10% mix you 'could' get away with it without getting remapped but there really wouldnt be a point to doing it as you will get hardly any benefits from it.
With a remap you will see a big difference.

Duncan,
You seem confused.
I was not referring to the requirement of the remap. I was referring to the poster saying that he "felt" a lot more power without a remap and you said "Oxygen", when I commented. I questioned that by saying my previous post, which you have just quoted.
So... is the affect that dramatic (i.e. the power) just by putting E85 in and no other changes (forget the lean issue)? As that is what I was questioning.

As has been said I would not advise running it unmapped..

The fact that the poster ran on pure e85 without mapping meant that instead of running at 11:1 on boost, it would have been running at possibly close to 14:1 (if we talked in terms of petrol stoich) As simon says, it will produce more power leaner but that is waaaay the other side of what is desireable. Lucky escape I reckon.

Well maybe he didn't put pure E85 in it.
This is an interesting topic anyway. I have been running my sti on a mixture between 5-10% bioethanol for almost 3 month now and is all fine. In holland is the only fuel reaching 100 oktane so this or 97 or bp ultima crap..... However my car was JGM'ed but not for this fuel, and I don't think it is running lean as my fuel consumption is only slightly better.
On the good side, car seems to like it, holds high revs well and feels stronger on lower end too. Engine/turbo sound v nice too -no weird rattles etc -as you'd get with crappy fuel.
BTW. Subaru says on std engine that you can use E85, but a max of 20% mixture - I guess more than that and you start melting internals

hagan051083 - Yes, you would need to tell your insurer. But if you tell them it is mapped for bioethanol for environmental reasons they should not penalise you I wouldnt have thought.

I am sure that if you have a std car converted to run on e85 that there would not be a financial penalty in terms of higher insurance for doing this. Obviously most of us don't run std cars so would have a hard job explaining that the remap was for environmental reasons only.

E85 is sold in almost every petrol station here in Sweden but AFAIK the car needs to be mapped for it to use it. You can't just fill up with E85.
On a Volvo rental car we didn't notice much difference between petrol and E85, maybe with E85 it was a bit more responsive but mpg was slightly lower too. E85 is cheaper than petrol too.

no i must have done about 10miles in it with e85 in it! northhampton abit far for me 2 go i need some where closer to liverpool. so any help on garages around liverpool that u would recommend?
#79
makes sense It drives v well on it. I hope I'll have some time to take it to RR, as I'm getting curious on figures.
#80
I've been trying to remember where I read this... but it was 3 month ago and have no idea really. At that time I readresearched anything I could about this fuel mix. In any case I asked my local subaru dealer and they also said I can use it.
#82
Please if any one knows any garages in liverpool who they would recommend for remap, advise an car care could they please private msg me! am in real need of your help ppl thanks

Could you have dual maps, with and without an E85 mix on a Simtec?
Or is it a case of once using, always using?
I'm quite keen on some free BHP/LB.
