Black Bear Tune

[Grocery Getter]

If your gonna try it I suggest a full tank of E85, I tried mixing 50/50 and the power is no where near what it is on 100% E85. You can always fill up a whole tank of E85 and drive off 1/2 tank and add 93 if you don't like it.

Dumb suggestion of the day
You could also just put 1/2 tank of E85 in an empty tank ......jzus I'm losing it today.

true, but I knew what you meant

i am thinking that putting e85 into your tank with a 93 tune wont do much for you compared to having your motor tuned to take e85.

Rational..

If e85 is actually 105 octane, then justin would lean out the tune even more to accept the e85 gas, which would in turn give you the proper fuel/air mixture. then you would see the power gains you want...

i could be wrong on this point... but im pretty sure its going to work like that.

I am sure he could tune for E85 and it would be wicked but you'd be kinda screwed here in the West. He could definitely get much more out of the fuel with a tune for it but then you would HAVE to run it and it is just not that readily available, especially here in AZ. I definitely can tell a difference, like how my truck runs, and have a station five minutes away so I go with it but I wouldn't tune for it since the station is not open on weekends and if you leave the city and go up to Flagstaff for the day your screwed and will ping all the way home when you have to fill up with 91. It's really not that big of a deal to run, try it and if you like it and it's convenient enough for you to get it certainly won't hurt.

My thinking is I have a 93 tune and so I am definitely not getting the most out of it with 91 so the E85@105 is getting the most out of my tune for sure. Could it be optimized for E85 and run even better on it, for sure but that is not practical.

Grocery Getter, I read your posts about the E85 and stopped at one of the two stations that carry it in my town. One being a few blocks away, my tank was just about empty. Filled it with $1.90 a gallon E85. A few miles down the road I could tell a huge difference, it's like a whole new truck. And this is with the 22's I just put on. Not sure why I never tried it before, but thank you for posting all the info!

For anyone that has a flex fuel truck, try it out!

Awesome! I'm glad I'm not crazy
Now your hooked on the corn and $1.90 holy crap! I pay $2.28 here in Phx ip from $2.02 a few months ago. It's good
stuff spread the word....

Yeah I couldn't believe the price either, 87 here is about $2.50. It was nice to fill the truck for $30.

Ugggh. I wish I could even GET e85 to try it out.

still to scared to try it.... heard it was ******* the motor but i cannot find any information about that one way or the other. If i go and fill up with this stuff and it turns out to give me more power.... i will be hooked!!

It will undoubtably give you more power. I still don't know what you heard about it being ******* the motor but it's not as far as I have been able to find out. Tens of thousands of vehicles run on it and fleets of government cars/trucks as well, the government Alt Fuel station is just down the block from my E85 station. The fact the same guy that wants to adjust his timing, run a supercharger , and has all systems maxed out by BB is worried about E85 being ******* the engine is what I find funny....... it won't hurt your rig TY and even if it is a little more work as far as combusting the fuel(just a wild guess at how it could be harder on the engine) it's not any harder than all the mods you would do to your engine if you had the means......
