NO!!!!!!!!!!!!!!!!
 
No!!!!!!!!!!!!!!!!!!!!!!!!!!
 
did I mention NO
 
E85 is a crock per liter it has less energy than 90%+ petrol it is unsustainable and its bull ****. you would have to replace the entire fuel system as the ethanol will eat seals and gaskets.
 
octane is higher so what? octane is a measure of detonation not of power. 
 
this is snake oil really bad no, no, no!

petersweeet, read the thread before posting such ill-informed drivel.

lol wtf petersweeet

jdmr288 - Powerband still dropped off quite sharply around 6-6.5k
 
James, I think you might be hitting the limit of the gen2 ECU/AFM, the main reason why you can't push past 270hp with this stock setup, without some form of tuning. The other side of the coin is that at 20%+ or so, the stock 440's are only going to be able to support around that level. A safer option to go further would probably be 550's and a fuel/ign controller like the ECU3 with the MAP sensor.
Also, if your still running an un-modified rail & tired pump, pushing the power band higher would be marginal at best.

  
 

petersweeet - your obviously not a drinker -:)
My momma once said "cars and alcohol don't mix" - how wrong she was.
 
The whole concept of this splash blending E on stock ECU's is to maintain as high a level of ULP98 (higher energy-smaller volume) as possible, while adding sufficient E to sustain the JDM ignition timing, and provide the other benefits of E, as possible..all within acceptable AFR levels.
On a standalone or stock ECU with a fuel/Ign controller, you can re-tune to accomodate larger injectors and as high a level of E as practible, tho there are limits where gains will decline, or injector sizing becomes an issue.
The power gains involved come from several directions (as discussed already) but by far the biggest is optimised Ign advance due to the properties of the added E.
 

Yea everything up until 6k was brilliant. I've filled up with just 98 this time around and can already notice that it's not as urgent as it was with the added E. Stock ecu/stock 440's and pump still being used.
There's just too much for me to think about doing with this car. I want to get the fuel system done and tune the car on the haltech but I don't really want to do it without getting a major service done which I don't want to do unless I'm swapping the motors as I'd want the motor out anyway for the service. Now my suspension is up in the air as it needs doing too. $$ = :'(

Hmm now its getting hard for me to keep track on this E mix. I top it up time to time but would have NFI how much residual would be in the tank. Just put my new 3" DP the other weekend and that gave it a new-found kick in the guts especially combined with the E -  it just spools so early now! now to get rid of the current poxy "cat back" and wack on the new exhaust to really see the 3SGTE shine. 

Ok guys ive got a few more questions...
I want to bd able to use this stuff out of the pump like you guys have, however i am running a haltec so the fuel really has to be the same.
I would be looking at possibly running the tank down to the last quarter, if not lower, then fill it with 10l of e10 and the rest with 98, obviously id have it tuned with the mix that i would run all the time.
Is this going to be a problem with the ecu since the e10 isnt always going to be 85% or since its going to be mixed it shouldnt effect it too much?
If its going to be a problem is there a way around it?

E10 or 'E-Flex'?
I thought you were just going to run straight E-Flex through it instead of mixing it with ULP98?
if you have a programmable ECU and injectors etc the sky's the limit.

It could be a problem, if you were to run say 10%E on the haltec programmed for 98ULP there would only be a marginal change, but say 20% could be different, dependant on the level of tune.
As for programming for the mix you select, you'd have to get some idea of the spread of this seasonal change, and program accordingly. I'm not sure what exactly they are talking about, if it's simply adding a higher % of ULP, that's no real issue, although the RON rating might take a bit of a hit at say 15% of 91 added, relatively speaking.
As far as octane goes, I've been messing around with dual tunes on 650's and apart from being long winded, I've come to realise just how much Ign advance this stuff will tolerate..you actually have to go looking for knock.
I think a chipped ECU like a Blitz Access would work very well on a 20% E mix. In fact I suspect the stock ECU's could handle an additional 2deg initial advance also, without trying it yet.
In fact I'd like to get my hands on a Gen3 Blitz ECU and give it a go. Be a nice little stock replacement power up package with 20%E.  (anyone got one f/s? -:)
