Guilt-toy Now Running On E85 !

[SimonR32]

Going to have a crack at getting a 204L drum of powerplus e85 when I get back from overseas and run a 50/50 mix with BP98... (I'm tipping about a 15% rise is fuel requirements?!?)

Should be interesting to see how the results go on a RB20 with decent boost!

So if this caltex blend will vary from 70 to 85 percent ethanol does that mean it is useless to us?

[wasnt me]

i wouldnt see it being a huge problem. will just richen up a bit on the lower blends.

unless you can do that on the fly, you'd have to have a map for E70 to cover all bases.

Yeah thats what I was thinking youd have to have a 70 map and 85 one which is to much of a hassle and will the blends be random just by luck what you get or you know when your geting what.

E70 would help with cold starting anyway. Here are the locations, none near me of course.

Hopefully more fuel companies will jump on the band wagon, they would be stupid not to.

aaaaand I just lost interest. Even more variance than the US...GG

sigh still either mix our own or run 98

[boostn0199]

I guess the option would be if you really want to take advantage of it is to get a map for our own mix whatever that is and run that map at track days and daily just run the 98 map.

what about running a permanant wideband AFR gauge and tuning the AFR's to suit e70, e75, e81.2 ect ect?

maybe leave the timing a bit retarded for e70 right through to e85, but tune the AFR's to suit each tank?

[Trozzle]

Probably more time and $$ than it's worth.

Would end up being easier to mix your own fuel in bulk at home or something...

Would anyone expect the cost of Ethanol to come down when this goes ahead? It will be more widely produced, so procuring E100 would be easier in theory....this would make mixing your own CONTROL fuel at home cheaper.

[SS8_Gohan]

The fueltown in Melb that sell Powerplus Ethanol, do mix their own. So if you really wanted, you could get E100 from them at the servo (as some of their race customers do)

E85 is yesterday news, come on E100!

[Trozzle]

I'm just holding out that United bring it to their servo and keep it a consistent 85%, otherwise Canberra gets shafted.

[Randon_I_Am]

well I've already got the AFR gauge, and my own nistune licence... so that part of it is nothing.

does anyone see problems in doing this?

[scotty nm35]

Ethanol will be going up in price as it stands at the moment. The fuel excise will increase it to $1.20L in the next year or two from what I have read.

Caltex have stated it will be significantly cheaper than unleaded which is $1.18 here at the moment so I cant see it selling for more than $1.

E100 is definitely the go, but cant legally be sold can it? I have seen a car running it from drums but realistically I cant be getting a drum delivered every week... Im stuck running what comes out of the nozzle.

speak to the guy down at Fueltown scotty - i reckon he'll let you fill up with E100 if you want. Granted, not out of the pump, but i'm sure something can be arranged

Maybe do the car and 2 jerry's, and keep the jerry's at home.

I filled there last night, 160L (car and 4 jerries) the attendant said I have a huge fuel tank. LOL

When I get home I have a 44 out the back I tip the jerries into which I use to fill the car, 20psi air pressurises the drum and a servo nozzle to fill it automatically so I am well set up for E100 if I could get it home.

I will speak to him next time im down there during the day...

[SS8_Gohan]

dude.... results MUST be shared if you get an E100 tune!!! :(

i thought i was crazy driving to Hoppers back in the day (50mins one way) to get a tank, plus 2 x 20L jerry's.... you've certainly taken it to another level! love your work!

[scotty nm35]

How much better will the e100 do though, bugger all I would say. I will be looking into it, what's another map when you have 20 on the laptop already.

With known mapping for E70, 85 and 100 I could automate it with the ethanol content sensor and set up a secondary (4th?) map on the Emanage to adjust, as long as the sensor is reliable... Not having to worry about what fuel I put in would be great. Im sure there will be units that do this coming out of the aftermarket industry as soon as there is infrastructure in place.

[conan7772]

How critical are the percentages anyway ?

I mean the Ethanol content will vary from the original tune from time to time.

What are the dangers?

[Trozzle]

rather critical when it's a possible 15% variance.
