This sounds interesting, there's a morrisons not to far from me that sells E85 so when i run out of Methanol perhaps i'll get mine mapped for it.
Anyone running higher %'s of E85?? 10 or 20%??
Would this cause any problems??

I run a Simtek ECU and only use my Meth/NF map on rare occasions, would do the same with the E85, so would be little hassle to run say 50%.
I have very large injectors so adding extra fuel shouldn't be a problem

Duncan.....i think i've got a Morrison near me that can do E85.
What do you think it'll do for me?
I'm currently on a meth and nf map.

i have a totally standard wrx 2003 i use a 50/50mix at the moment on a rolling road my bhp was 245.6 an 237 ft-lbs of torque! an not having any problems at all with 50/50mix thats v-power / e85!
an it felt more powerful when i ran a 100% mix with no big problems! it felt better than ever. The engine light did come on, the fault was my car was it was running lean.

It is sold as an alternative to race fuel in that context and as such is half the price of race fuel even if you went for 50 litres (with pretty much the same results).
Its not a price I want to pay though either hence why I fill up a few jerry cans at each Morrisons visit.

Hi Duncan,
I've been trawling RR and can see a lot of threads about the guys over the pond tuning for E85, but everything I've read so far is converting for straight E85, so injector scaling is reduced by ~ 30% and WB02 AFR's divided by 1.5 to get true 100% E85 readings.
If I was to start(on the WRX first) with 550cc's(from Spec C) and a 10% mix of E85 would I reduce my injector scaling of 550 by around 3-5%,(around ~530). How would I arrive at the correct AFR readings on my LM-1.
So many questions!
Cheers Paul

it was only really a test to see what that fuel actualy does! the petrol station that sells this is a good 20mins drive from me! i just wanted to see what mix my car can / cant take an the powewr gains! one day this fuel will be sold at more pumps. so when that time comes i might actual go for the switch. an get my car mapped to it / any other changes they say is needed. the next thing for me is a few mod's, just thought i would share with you people so u know the power gains etc, for when that time comes when u can get it at most stations, so you lot can make the choice of normal petrol or e85 an can see the gains u do get from e85. At a 50/50 mix +20bhp, i would really like to know what i would get at 100% mix! but that will have 2 wait for now!
An thanks for the advise but i had to test it for my self an see the results! An i will not be running all the time coz am not driving 20mins out my way every time 2 fill up.

my car isnt mapped for it its still standard!

Can you not grasp the fact that it is a bad thing to do ?

hagan : These guys are trying to give you good advice. When the engine runs full power a lot of heat is created. In part the amount of heat is determined by the air fuel ratio. With a weak AFR, picking up a piston in the bore is a likely consequence. Repair cost could be, typically, £2,000.
The required AFR varies from fuel to fuel and your car on the standfard ECU is intended to run on 98 RON unleaded pertol.
When you add E85 the mixture or amount of fuel to obtain best/safe burn conditions in the engine, has to be far richer. ie more fuel.
On a 50% E85/Petrol mixture the additional fueling required is substantial, to the point that almost inevitably you will seize your engine if you run E85 WOT for any time.
Without remapping you cannot run E85 on a strong mix unless you want to test your engine to destruction and have no problems with your car VOR for a week or so.

Eh, I looked last week and the nearest was about 90 miles away..?
Tamworth would be fine as M&D live near and I'm over at least once a week..
Right, now I'm thinking..

Duncan,
Do you know how BIO ETH is manufactured.... is it the same as BIO Diesel, i.e. some bloke just throwing specific mixs in to a tank.
My only concern on this would be the controls used to ensure the "mix" is the same..... not sure if this is a real concern? One good thing about race fuel, is in theory each container should be exactly the same fuel spec (I say "in theory" lol).

There is a Standard it has to adhere to - Quality control of bioethanol - Process Engineering
You don't always get a consistant V-Power tank.....
