Why does it mention E85 on their website if its no good? lol 
Forget this bio green crap what happened to good 'ol Toluene?? 
 
percentage of toluene mixed with 98RON:

10% - 102 octane
20% - 110 octane
30% - 115 octane
40% - 120+ octane

Of course not, your still running the standard tune.. therefore, its injecting approximately the same fuel.  it may just be running slightly leaner then standard (which is stupid rich anyway)

/\ standard = unmodified
adding bigger injectors to a standard car will only result in one thing
did you even read the thread properly???
even worse james just posted somethign directly relevant to what you just said before you said it.
 
in your car it a total waste in its current state cause its not tuned for this fuel,  
 
for a stock standard car the tune is the same, as James mentioned earlier so same amount of fuel is going in, except the fuel going in this time burns way way better than the older stuff that was going in (98 ron, optimax, ultimate, synnergex, vortex etc), so there's less wastage, more energy is produced by burning all the fuel because there less knock encountered so ecu doesn't dump fuel in to the engine to compensate so the engine actually runs like it was running in Japan where they have the 100ron fuel which is what these cars are tuned for..
to make it simpler the cars will behave like a car running on a power fc with a mild tune ---  why????  because the stock ecu was tuned for 100 ron which we dont get here
when the pfc is tuned here its tuned for 98 or whatever fuel you want to use so the tune is optimised for the fuel your using
with the stock ecu it cannot be tuned so the fuel RON has to be adjusted to get the best and this is done by adding the 80/20 mix as mu man suggested  
 
the only downside im seeing is the seals etc swelling and ruining the pump and injectors
although i wonder if just using the 80/20 mix will result in damage to seals

surok: I wasn't mocking you, it's just that digging up a post from mr2oc on a similar but unrelated matter, and posting it without any reason, led me to think you were making some kind of statement, rather than asking a question? anyhow, if I made you feel that way..I do apologise.
 
purple5ive: You summed that up pretty darn well..
 
On the rubber parts: I've seen pumps & hoses affected by Ethanol, mostly from E10 where the stock pump is still used, and mostly done a lot of K's. I experienced it personally in an r33 where I ran E10(95 then) for 18 months. So there's something going on there, over time, and they come out will swollen seals that eventually stop the pump from running. On the other hand, I suppose any pump over 10 years old is rather tired anyway, and needs replacing with an ethanol compatible pump..migh as well be with a smile.
 
The rubber lines are easy enough to fix.
 As for injectors, never seen or experienced any issues, tho I have heard some reports (like tots) of inj seals swelling or inj failing, and some reports from o/s about deposits building up.
The deposits I think, are from the the Ethanol (and this is 100%) breaking down from age, and forming varnish/gum deposits, which it will do after long storage. Plus guys in the northern states & Canada tend to store cars over the winter, so might be something in there. Usually  a couple of tankfulls of 98 cleans things up, unless it's let go badly.
AS for the inj seals, most of those are now neoprene anyway, so I assume its the seals themselves.
Injectors..no idea, havent seen any, but all I can think of is if they are cad plated, maybe its pitting. It will affect cad plated items, Ive seen it on pump bodies, and where cad plated tanks are involved.
Hope this helps..just trying to give a complete view, not just the up side..although that is the best mod for less than 20 bucks your ever going to find.
 
 

A bit more info: 
Got my hands on a '91 rev1 donor car over the weekend. The car is going up for sale at  Southport next week if anyone is interested, at around 12.5k. The car is bone stock apart from a pod filter of some sort and an ebay'ish looking IC.
After a set of plugs it drove pretty well like you'd expect, responsive down low, good mid range, not a lot up top.
After switching to 80/20 the difference was...well, almost astounding. The car was completely different to drive, better bottom end, smoother power (even at low revs) and felt like it had a torque boost. Into boost the ceramic turbo spooled like crazy, and trying to be careful with it was very hard. I tried to set the MBC reasonably conservatively at <14psi but ended up at 12, although it was overshooting to 13, and occasionally 14, so I didn't mess with it. I think the stock exhaust would be struggling a bit.
All indications are it's still running stupidly rich at those boost levels. I'd like to see it on a set of rollers and  see what the AFR's are like.
 
 
 
 

why do you think its running so rich even after using the 80/20 mix i thought it would have leaned it out a bit more which is where the extra power is coming from...
 
did you try an ECU reset to make sure it back to factory settings and clearing errors etc

So for AFR tuning under WOT/boost the MAP ECU2 would be definitely worth it on the gen 2 ECU than for the Gen 3 because the gen 2 just pours in tons of fuel basically at those levels? thats just killing power/economy.
I'm not really interested in top end as the CT26 hasn't got any but would like to lighten it up as its just a waste of fuel.
