e85 kicks ass
 

my friend finally got the balls to do the e85 OFT tune. It is a serious upgrade. This car should have come from the factory like this. The engine seems to run much smoother. The idle is very stable and the crickets have completely disappeared. Anyone know of a website of app of gas stations that g-have e85 fuel?

Don't know how current info in that thread is. You can also use:

I use gas buddy on android. switch the settings to e85 only so it only shows e85 stations.

Are you in SE Florida by any chance?
I can point you to a couple of stations.

I haven't had such luck with E85; car feels sluggish, feels like there's no power down low. When I pull away in first I have to give it more gas than on stock, or on the OFT 93 tune (which is really great). Crickets are there sometimes. And between 2500 and 3200 rpm there engine sounds a lot louder than before, but there's no knock, and everything appears to be ok in my data logging. :(

Yeah, I do most of my driving in pembroke pines and downtown ft lauderdale.

Thanks!

Nice! The one I've used is a Shell on Sheridan and Pine Island Rd. I've also seen it on the Mobil at Miramar Parkway close to 172 Ave, but have never gotten it. Saw someone else get some before I got the tune. Where do you get yours?

I dont know about your area, but I drive by E85 gas station almost everyday.

LOL pine island and sheridan. I live pretty close to that one.

Since they never post the price of e85. How do you know without visiting every gas station.

Hm, I wonder why that is. Can anyone shed light on this?

Considering going with an OTS E85 tune on my relatively stock 2014 FR-S.

I live in southeast Florida. I use cheap UGas and Westar E85 because that's what's close to me, and it's night and day from 93. Gears 1-3 should pull harder. In 4th and 5th on 93, the car would slow down it's acceleration, but now on E85 it continues pulling like it's in 3rd. I've been on corn for about a year, no problems with the car or the quality of cheap gas stations.

Well...there is only 3 E85 gas station in my area..the one closest to me is 5 miles, so I can ignore other station that is 15-20 miles away from me..E85 is cheap and the price is very consistent..you dont need research to know the price...

Steve99 is helping me figure this out over on the How to Run E85 on stock 86 FRS BRZ thread. As of right now he wants me to log some full throttle pulls so he can look over rthe data, but so far most things seem okay. I'll update when we have more info.

Are those the ones in the Miami Lakes area? My fuel trims show me I'm close to or just over 70% ethanol content, but it might be worth a try to get gas somewhere else.

When I do my pulls for steve99 I'll let you know for sure I notice a difference in gears 1-3. Right now, pulling away from a red light in traffic (so not fast) the car feels hesitant, and I'm finding myself having to ride the clutch longer (even on first) so I won't stall or jitter around. Once I get going it feels about the same as 93.

Probably around E70. And in the Homestead area, i'm too far to get good corn. My closest station is 5 miles, second closest is 15 miles.

I never checked the % I was getting from the e85 I buy. Since its a shell station i really assumed it would be closer to 85. The engine noise you hear at 3200 rpm is the same noise I get on the stock 93 tune also for the OFT. Its normal. The other issues are not normal. I do feel the need to push the gas pedal down a little further when leaving from a stop if I am driving calmly. I do not know why this is but i also can feel more pull from the car once it gets going. If you get a tune that works better on this gas let me know.

OTS tunes are best until you get custom. When starting from a stop, does the pedal feel like it has a dead spot or does the engine bog? If you have an aftermarket intake, you may need to scale MAF. These tunes do need some miles to get rid of any dead spots in the gas pedal sometimes too.

I think its more of a dead spot. I am on my 3rd tank of e85 currently.

Do the OTS E85 tunes help improve throttle sensitivity? I feel like the stock throttle mapping is a bit mushy and not as responsive as I want.

I thought the same thing too, but according to everyone on the How to run e85 thread, most stations will be closer to 70%, some even less, specially for winter. The Shell I have by my house says "minimum 70% ethanol," but when I mentioned this on the other thread, everyone said it says that but their flex fuel sensors sometimes show less or more.

I didn't get any strange noise on the 93 tune. I even flashed back after three tanks of e85 to make sure it wasn't just in my head, noise-wise and sluggish driving-wise and no, the 93 tune is quiet and smooth. After two months of 93 I'm back on e85 and I feel the sluggishness as well as the extra loud throttle sound between 2500-3200 rpm.

Will let you know if I get any tweaks from the other thread.


The throttle definitely has a dead spot, and I'm sure that's contributing to the struggle to get going. Last night it took a few seconds to back out of the parking at work.. it was pretty sad lol. Since it's on an incline, the car felt like it had no power to get back onto the even surface... -_- I tried giving it more gas each time, and could hear the engine winding louder, but the car wouldn't move and would roll back to the bottom of the incline as soon as I backed off the throttle just a bit. It wasnt until I gave it more throttle than needed, and modulated the clutch, that I got going. I just recently got an air inlet tube, but that's all the aftermarket I have and feels the same as when I was on stock for three tanks earlier this year.

I feel like the mapping on the 93 tune is much better than on the E85. Feels nice and progressive with more response. As you can see, the 85 tune seems to have a dead spot right when you start pressing the throttle, the rest of it, to me, doesn't feel as good as the 93 tune, but you should read what others have to say in the How to Run E85 on a stock 86/FRS/BRZ thread, since it seems I'm the one having issues.
