Enyone use or herd of the new bullydog programer for E85 engines? I would like to get one for better mileage when running E85 and some more HP to. Bully dog says you can switch to gas when running the tuner also.

 

e85 sucks ***** with the 50-60 cents you save at the pump you will be going back twice as much as using premium trust me i tried it , belive it or not its cheaper to use premium than e85 its garbage ...

the only good thing about it is that it's 104 octane and it gives you a "slight" boost in hp



Go With Charlie Wheatley FTW !!!!!

 

Not to **** on your parade m3srt, but I must instill some additional thought into this thread that is contrary to your statement. E85 is not Garbage, it is Alcohol. Mixed with a 15% blend of Gas and Additives. This fuel is a nice alternative to high octane gasoline when run on engines designed to take advantage of it. An engine designed to run ideally on E85 will more than likely make more torque with less throttle input, thereby giving greater miles per gallon so to speak than an engine that was designed to run at a compromise on 87 octane gasoline (running E85 with just a factory tune to compensate). An engine designed to run E85 will by nature be able to have higher static compression ratio, somewhat increased ignition timing advance (will vary some given the slight difference in burn rate from gasoline), as well as have the potential to run higher boost pressures with reduced chance of detonation. In order to compensate for the decreased energy content of Ethanol in the fuel blend you will need to use higher rates of fuel flow i.e. modify the fuel tables in the ECU, and possibly upsize the fuel injectors.

And going to the fuel pump twice as often? That's rediculous, maybe if you drive with a lead foot 70% more often than when you were running premium, but if you don't change your driving habits you're only looking at a 10-20% increase in fuel consumption. Right now with premium at $2.20 in my neighborhood, E85 would run (based on your $.60 difference figure) ~ $1.60 that's 27% less cost. If you can realize no more than a 27% decrease in fuel economy I see it as a win, just in octane rating of 105 vs. 91 with California grade premium gasoline.

Again, in order to realize the benefits of this fuel you have to have an engine that is optimized for it. At current GM/Ford/others has introduced a stop-gap measure called flex fuel that allows consumers to run 87 octane gasoline as well as E85 ethanol/gasoline blend fuels. These are not, I repeat NOT optimum engine combos to take advantage of E85. This is just a way to get high ethanol blended fuels a demand base in the market, which unfortunately has a few cons in implementation for the early adopters. Give it a few years for Ethanol or other alternatives to Gasoline to come to market and you will see the manufacturers come out with more optimized solutions.

 

well when i used it quite a few times it went right through my engine ... just imo



has anyone else used it on here id like to see MPG comparisons ....

 

i just got 20.3 mpg with my 93 octane tune doing 75mph down the interstate for 200 miles and i know i stomped it once trying to **** off a hemi

I normally get 21-21.5mpg on the highway with cruise set

 

you might as well save your money and get a good tune. I know others will agree on this.

 

I Agree with this statement as well. I apologize for not replying to your original question O.P., take a look at EFI Live and HPTuners for good tuning suites.

 

 

i ran e85 for awhile. Honestly the thing i liked most about it was the sweet smell while cold or in traffic compared to the gassy fumes i normally get due to not having cats. I noticed my fuel mileage was down and i did the math and it cost a **** hair more to run it compared to gas, only like two cents a gallon though. But as stated my engine is not built primarily for ethanol, and i could not fathom that due to limited availability, especially if you go on road trips you better have an 80 gallon tank in the bed. I do think if it were more readily available i may have built a 12:1 compression motor and been pretty happy with it.

 

Thanks for the tips people. I agree with the mileage figures I get 1-2 mpg less also if I get this tune from bullydog maybe ili be happy.
