Jellybean Posted December 16, 2014 Share Posted December 16, 2014 Looking at the video , the ECU mixes 91 pump gas and alcohol on the fly as its needed to make 104 octane, as using race gas limited the car to 100 mile range Maybe RyanG can come up with something https://www.youtube.com/watch?v=8UZNDEaDlro Quote Link to comment Share on other sites More sharing options...
CanisLupus Posted December 16, 2014 Share Posted December 16, 2014 E85 has an Octane rating of 107 over here. In Winter mix it goes down to E75 approximately which equals to a minimum of 104 Octane. Which in fact is the same as mixing it on the fly. Quote Link to comment Share on other sites More sharing options...

Wez Posted December 16, 2014 Share Posted December 16, 2014 Syvecs and flex fuel sensor should do the trick. Quote Link to comment Share on other sites More sharing options...
jjs_82 Posted December 16, 2014 Share Posted December 16, 2014 Ours is 95 Quote Link to comment Share on other sites More sharing options...

JamieP Posted December 17, 2014 Share Posted December 17, 2014 Methanol and fuel flex sensor works just as well. I wouldn't bother with a water/meth kit personally. Quote Link to comment Share on other sites More sharing options...

Jellybean Posted December 17, 2014 Author Share Posted December 17, 2014 Methanol and fuel flex sensor works just as well. I wouldn't bother with a water/meth kit personally. Problem is getting some here lol We are so close to the UK yet so far I tried to source Toulene but nobody would sell it here and too $$ from the UK, VP or Sunoco race fuel was expensive as you needed a Hazard Chemical License to transport it it is available at our yard in Letterkenny at €130 all in per 25 litre drum. If you just want a small quantity the carriage might prove costly as it is likely to run to €80 + vat to do the delivery. it was woking out 15 litres of 116 octane race fuel per tank to get 100 octane @ 69 GBP Also looked into AVGAS , as I live out by the airport but it was just starting to get ridiculous LOL Quote Link to comment Share on other sites More sharing options...
Wez Posted December 17, 2014 Share Posted December 17, 2014 Also looked into AVGAS , as I live out by the airport but it was just starting to get ridiculous LOL I tried to get my hands on some AvGas a while back, apparently you need proof of plane ownership to buy it now, or know someone on the airfield Quote Link to comment Share on other sites More sharing options...
Fitz Posted December 17, 2014 Share Posted December 17, 2014 On the topic of Octane, in Canada they have 3 levels at the pumps for 'gas'. Regular 85, Premium 87 and Supreme 91. I assumed that Octane levels were standard wherever petrol was sold. Obviously not [emoji28] Quote Link to comment Share on other sites More sharing options...

Jamie so i dont go buying unecessary kits you just put this in your main tank and the syvecs and fuel flex does the rest? Im going to an S6 in January. I know meth eats at aluminium and I have full hard lines and a swirl pot etc. Assuming as bio ethanol is is just alcohol basically it shouldn't cause any issues with the fuel system? I was looking at a progressive meth injection kit however this would have to be a seperate injection system completely. It is easier not having to worry about that but with just putting it in the main tank you cant be exact to the mixture that you're creating surely? What do you do when filling up? fill half a tank with petrol then fill the rest with bio ethanol? Quote Link to comment Share on other sites More sharing options...
Wez Posted December 18, 2014 Share Posted December 18, 2014 It doesnt need to be exact, thats what the flex fuel sensor is for, it works out the ratio and tweaks the fueling and ignition accordingly Quote Link to comment Share on other sites More sharing options...
Guest gtr_garner Posted December 18, 2014 Share Posted December 18, 2014 (edited) i know that's how it works but i mean you're going to get differing levels of performance dependant on how much is in the tank etc. Whereas with a standalone setup the amount entering the engine will be the same all the time. Are there levels to what the syvecs can compensate to? Can they read from 0% ethanol all the way up to 100% say? Not that i'd ever put that high a mix in. Obviously the map will be done to whatever mix we have on the day or two and the ecu will just run off those settings and tweak using presets within it for higher or lower amounts of mix? Obviously with the fuel flex its a hell of a lot safer with redundancy built in, just wondered whether anyone had a particular way to keep the mixture as regular as possible.

It will read to whatever you have mapped for, mine reads between 7% (v-power is 7%) and 60% you could map for 100% if you want. Quote Link to comment Share on other sites More sharing options...
Guest gtr_garner Posted December 18, 2014 Share Posted December 18, 2014 I had just read one of your posts about it in another thread and was about to say dw I understand now. You beat me to it!
