E85 Ethanol Fuel

[SuckSqueezeBangBlow]

I'm wondering if anyone that has access to E85 ethanol fuel has had their car tuned for it. I.E have a dedicated "E85 tune" on their flash tune box?

I'm interested to see what sort of power can be made and what sort of savings they are making.

Unfortunately, I can't find E85 fuel anywhere in Sydney.

United servo in Rozelle has it mate.

I run my car on E85, makes awesome power.

But seeing as you need to run 30% more of it, you are not really making any saving.

I would not recommend using it in a daily as the trips to Rozelle would become quite annoying.

Rozelle is only 15 min from where I live, good to know.

So do you have an E85 Ethanol specific tune to make the good power?

Dave's car has been specifically tuned for E85, the standard petrol map would be too lean to make power, and in the reverse situation 98 pump fuel on the E85 tune will result in massive over fuelling and too much timing. Its not too much of an issue with the flash tuner cos it can store multiple tunes, but you would have to make sure the tank was very empty when changing from either fuel.

thanks for confirming that Senna, I wasn't 100% on that but yeah was assuming you would have to empty the tank.

But that's what I love about the flash tuner - the 3 maps (so why not have one for E85?).

Definately, an E85 tune would be good for dyno days or the drags, you just have to make sure that your fuel system has head-room, if you max out the injectors using 98 pump, you'll be likely to make less power on E85 as you need more fuel to make the power. From what I have read the Siemens Deka injectors are good for up to say 450rwkw in the falcon, but you'd be more likely to just reach high 300's running E85. Something to keep in mind!

read some where then the stocks run out they will not carry E85 anymore at Rozelle

maybe they change there minds

Hey,

I live nearly an hour from the United but I now run my 20b cosmo on e85 my Fg XR6 ute SInCE NEW . Wifes 4wd my old man runs his liberty gt on it I re built my dirt bike to run it with a 13:1 piston and f*ck its got more power now. Oh + the lawn mower whipper snopper and chainsaw.

Once you tune to it once your hooked.

I have a tank for the back of my ute and I just fill up 200 litres every time im coming back from near there and hold it in 44s. with higher comp engines you can get better economy but for sh*t box motors designed for CRAPPY petrol you get 15 -30 % worse.

Dont forgett you get more torque and that helps with economy.

If any ones wants a tune on it let me know because Dynowog from Vic is coming up soon to do some tunning . And I am pretty sure he can get you great economy out of it as the higher octane allows you to run it lean on cruise.

Oh as for having an empty tank before switching to the 98 tune.

My fg (NO TUNE ) runs on up to e75 at the correct A/f ratios and makes awesome power at e85 it goes may to rich for e85 even
