Don Mega Posted December 14, 2015 Share Posted December 14, 2015 Id just give up mate,your figs are showing 11 is right for trafic on E85, and 15 /16 on E20.. No one uses any other fuel in E Compat Engines ive known anyway. Cruzin at 85/90 on E20 should get you 20 kpl easy, mine did on sunday during a 2hr X2 run. Do you have any factual evidence to back your claims or are are you basing your rebuttal on unsubstantiated hearsay ? Link to comment Share on other sites More sharing options...
DavisH Posted December 14, 2015 Share Posted December 14, 2015 (edited) I wonder if a motor can be retuned to run on one grade of petrol only. Because these engine can run on multiple types of fuel, I think that they are not optimal for any one in particular. Perhaps a piggyback ecu like gredddy e-manage, unichip, could be used to tune fuel trims to optimise the use of e85 to give it better power and economy.

VocalNeal Posted December 14, 2015 Share Posted December 14, 2015 (edited) Power is always going to be less with alcohol based fuels. Not my experience but...if that is what you believe. That must be why NASCAR and Top Fuel dragsters use it. http://iqlearningsystems.com/ethanol/downloads/Racing%20Fuel%20Characteristics.pdf I wonder if a motor can be retuned to run on one grade of petrol only. Because these engine can run on multiple types of fuel, I think that they are not optimal for any one in particular. Perhaps a piggyback ecu like gredddy e-manage, unichip, could be used to tune fuel trims to optimise the use of e85 to give it better power and economy. Absolutely they can. From what i can gather the compression ratio would need to be raised to about 14:1 from the ,say, 10.6 on a Honda HRV. The Honda already has wide band injectors as it can already run on E85. Don't know about ignition timing etc. On a turbo car with the requisite injectors the boost could be turned up a bit That would give more power at the expense of fuel volume usage. Bottom line for everyday drivers is still that every vehicle is different and ALL types of fuel should be investigated before arriving at one's personal conclussion. Again just because it is cheaper at the pump does not mean overall it is cheaper! I'll get my hat now.

bearpolar Posted December 14, 2015 Author Share Posted December 14, 2015 Yeah but who knows what cars are best tuned to, i looked for hours.. Is the 1.8 honda engine better with e20 or e10 , i know e85 is crap unless it drops to 15b Link to comment Share on other sites More sharing options...

They seem to do lot of tuning to get cars to run well on E85. They dropped a k24 into a honda city and get 700+ whp on E85. Many of their modded cars are made to run on E85.

Ive got friends running LS motors (heavily modified) with a "daily" tune for benzine 98 and "race" tune with E85. 650hp 98 for the daily and 900hp E85 race tune are common. Forced induction though.

Gary A Posted December 14, 2015 Share Posted December 14, 2015 It is more economical to run my Ford Focus on E20. That's mainly because if not E20, it requires 95 octane which is quite a bit more expensive. The Focus gets between 11 and 12 KPL local driving and about 14 highway at speeds of between 100 and 120 KPH. Link to comment Share on other sites More sharing options...
bearpolar Posted December 14, 2015 Author Share Posted December 14, 2015 its simple. is there a chart to know ON CARS MANIFACTURED FOR E10 E20 AND E85 that shows what gives the best economy/performance ratio The information found online makes absolutely no sense most of the time and i know we have a few car pros in here that could answer this clearly in less than a minute. The reply would be saved in google and generations of people wondering about this will finally have their info. Link to comment Share on other sites More sharing options...

The reply would be saved in google and generations of people wondering about this will finally have their info. I would love to find one too, there are too many variables in the tuning to state which will ultimately give the best. That is why my chart only uses the theoretical energy available to each fuel. There should only be minimal differences between gasoline and gasohol E10 and E20 in engine efficiency so theoretical values should be good enough. Subjectively can anyone tell if your car has 3.3% more power on E10 versus E20? E85 cars would have to be highly modified if you wanted to have the same power as a E10 based fuel and would have a much higher fuel consumption to achieve it. Diesel Engines are ultimately the only one that currently have a 30-40% better efficiency than the gasoline engine so have the best economy/performance ratio.

bearpolar Posted December 15, 2015 Author Share Posted December 15, 2015 switched back to 91 after emptying the tank and im getting terrible mileage compared to before.. maybe its just for the first few km. Now i notice how much power i lose. 85 makes a huge difference in power on the HRV. If mileage doesnt fix itself might just keep 85, pay a bit more per month and enjoy good performance a mid rev Link to comment Share on other sites More sharing options...
VocalNeal Posted December 15, 2015 Share Posted December 15, 2015 91 what you'll need to go to 95 Benzine for the whole gambit of fuels? Just found this http://www.edmunds.com/fuel-economy/e85-vs-gasoline-comparison-test.html Link to comment Share on other sites More sharing options...
bearpolar Posted December 15, 2015 Author Share Posted December 15, 2015 (edited) Benzine isnt available anywhere afaik Gonna try manual mode, my auto mode seems like its giving me shit mileage lately.. Auto without econ mode auto switch gears at 2000 rpm and econ mode 1600. No power and probably loss of mileage by taking so long to get to a higher speed.. Pretty sure accelerating moderately faster in first and second to 40-50kph and then cruising is much better than going through 5 speeds to get to 40-50 It's probably happening because of the 25kph average i get in phuket, computer adjusted by acting like a dumbo Edited December 15, 2015 by bearpolar Link to comment Share on other sites More sharing options...
bearpolar Posted December 15, 2015 Author Share Posted December 15, 2015 so now 60km back on gashol 91 i get 10-11 on every trip instead of 12.5-15 even with eco mode guess e85 <deleted> something up and now ill be stuck on e85 for good Link to comment Share on other sites More sharing options...
bangkokairportlink Posted June 13, 2017 Share Posted June 13, 2017 Do you know if all cars that can use E20 can also use E85 ? Thanks. Link to comment Share on other sites More sharing options...

No, cars that can use E20 may not necessarily be able to use E85. Only use E85 if the car is compatible. E85 cars can use E10 / E20. Link to comment Share on other sites More sharing options...
