nigelboyne Posted January 24, 2010 Share Posted January 24, 2010 lads any help or advise i was thinking in summer to have the supra bpu mapped for E85. the station is a mile away from me. is there much point ie pros or cons.and what do i need to upgrade. the updrades will go towards my single or big twin conversion in future. 2/3 denso uk fuel pumps with new fuel lines. will the 550 injectors need upgrade and anything else i need. any advise be welcomed Quote Link to comment Share on other sites More sharing options...
tony tt Posted January 24, 2010 Share Posted January 24, 2010 Thats fine if the e85 is down the road from you but is it readily available if you go further afield? Is there many fuel stations that sell the stuff there? Quote Link to comment Share on other sites More sharing options...
Kirk Posted January 24, 2010 Share Posted January 24, 2010 the mixtures can be inconsistent meaning 1 batch they get maybe good and 1 may be crap which isnt good.. its not exactly ready available across everywhere either Quote Link to comment Share on other sites More sharing options...
JamieP Posted January 24, 2010 Share Posted January 24, 2010 Are you fitting a ecu and injector upgrade? ive read e85 is very inconsistant in america (not sure about here) so map on the safe side. Quote Link to comment Share on other sites More sharing options...
nigelboyne Posted January 24, 2010 Author Share Posted January 24, 2010 ecu is in already fcon v pro. 550 s prob need to come out id say. 1000/2000cc. 2 stations in dublin and a station within fill ups around the country. getting more popular only 90cent liter compared to 130cent for petrol. lots of ford/ saab bio fuel cars now over here Quote Link to comment Share on other sites More sharing options...
tony tt Posted January 24, 2010 Share Posted January 24, 2010 My car ran lean and blew up there cost me €5000 to fix it hence why i moved back to the uk. I would be carefull what level of tuning your wanting to achieve it could be costly there bud. I was trying to run bpu well as close as i could most i could run safely was 0.9bar. good luck with your mapping as jamiep says play it safe.

nigelboyne Posted January 24, 2010 Author Share Posted January 24, 2010 can i have a switch to go from the stock ecu to the fcon or is this possible Quote Link to comment Share on other sites More sharing options...
JamieP Posted January 24, 2010 Share Posted January 24, 2010 can i have a switch to go from the stock ecu to the fcon or is this possible No but twin maps on the f-con might be possible, on stock twins id not bother tbh, a lot of cost and minimal gains.

nigelboyne Posted January 24, 2010 Author Share Posted January 24, 2010 jamie if you were to run your set up on this E85 would you make even more power and is it safer Quote Link to comment Share on other sites More sharing options...

No, id not run it for this reason. Quote Link to comment Share on other sites More sharing options...
nigelboyne Posted January 24, 2010 Author Share Posted January 24, 2010 think i will scrap the idea so. will stick to adding 10 or so liters to a fill up cheers Quote Link to comment Share on other sites More sharing options...

tony tt Posted January 24, 2010 Share Posted January 24, 2010 Why could you only run 0.9 bar? I think it was down to poor detonation which was causing it to spike apparently. I was advised to keep it there and not raise boost levels to stay on the safe side and after spending 5k i took his advice hence the reason i moved back to the uk.

Ah crap i'm running 1 bar can i get it mapped or something to make sure i don't do any damage. Quote Link to comment Share on other sites More sharing options...
tony tt Posted January 24, 2010 Share Posted January 24, 2010 If you have an aftermarket ecu mate im sure it could be mapped to suit but i wouldnt expect to see big figures mate. E85 is the highest octane fuel there and as previous posts have stated its not 100% all the time. E85 was just being introduced when i left all i had in tralee was 95ron and had to use an octane booster with every tank and it just didnt cut the mustard. Where abouts in ireland are you? Do a search and see where your closest E85 pump is bud. Quote Link to comment Share on other sites More sharing options...

Do a search and see where your closest E85 pump is bud. I'm in westmeath. I think dublin is the closest E85 pump to me. I always used shell v-power but since thats gone i had to use 95 octaine. I've only put about 5k miles on my car and owned it over 3 year now so not much miles on 95. Also i'm now using E5 from maxol. Maxol claim its 99 octaine but i don't know. Did you car just bang suddenly or did you get any warning? Quote Link to comment Share on other sites More sharing options...

E5 i have heard is 99 though from what i can gather i did do a search on maxol and its right enough apparently. I wouldnt use just 95ron its too lean if you must use it put an octane booster in aswell millers oils have a booster called cvl turbo which was the best one i found to use although it is expensive 1 bottle only treats 20litres of fuel. Is the E85 not for newer cars with bio engines or something?? E5 is the one i would use if i was still there. Quote Link to comment Share on other sites More sharing options...

Thorin Posted January 25, 2010 Share Posted January 25, 2010 There is a good thread on this somewhere. I believe that you use a fair bit more E85 fuel than normal fuel so probably need larger injectors. Your whole fuel system needs to be suitable for alcohol based fuels. You need an ECU capable of supporting flex-fuel sensors due to the different blends of E85 throughout the year. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 25, 2010 Share Posted January 25, 2010 Do you want to run E85 for performance gains (more octane allowing more boost), or do you perceive it as a fuel that will cost less? If you want more boost just buy Avgas and add at about 20% to the poor unleaded you have available, it'll cost less than a proper E85 conversion.

nigelboyne Posted January 25, 2010 Author Share Posted January 25, 2010 performance and safe boosting to 1.4+. couldn careless bout fuel consumption or cost. chris is this avgas the same stuff i delivered for small planes and helicopters thanks Quote Link to comment Share on other sites More sharing options...
dude Posted January 25, 2010 Share Posted January 25, 2010 can i have a switch to go from the stock ecu to the fcon or is this possible There are a series of switches on the F-con unit, these switch between maps or you can have your own switches in the dash to do the same thing.

Chris Wilson Posted January 25, 2010 Share Posted January 25, 2010 performance and safe boosting to 1.4+. couldn careless bout fuel consumption or cost. chris is this avgas the same stuff i delivered for small planes and helicopters thanks Avgas 100 LL is what you need, guaranteed 100 octane, with a bit of lead in it, LL standing for Low Lead. Your O2 sensor(s) will have a shortened life, but you can get it easily and it's a LOT less hassle and expense compared to converting to and mapping for Ethanol. If you literally aren't bothered about cost just buy some decent high octane race fuel and mix it with pump stuff. Quote Link to comment Share on other sites More sharing options...
