So what is e85
 

And what do tunes do? Do you have to change the gas your using? Is it worth it? Bad for engine? And will it get me laid? I also order an srt header back. Will it work fine w/ it? How do you resset ecu? Is there a how to install e85 vid? Please help I'm a very stupid chill person :bonk:

Start educating yourself in this thread.http://www.ft86club.com/forums/showthread.php?t=13307 A lot of pages I know, but there is a lot of tuning info.

You can tune on regular gas and expect gains of 10-20 whp

E-85 tunes are seeing 30+ whp gains (but less MPG) Requires special tune and switching fuels

Is it worth it? Of course, I will never go back to stock tune.

Better low end torque, better top end power, torque dip is minimalized, better throttle response, smoother idle (fixes idle dip) Other special features can include launch control, flat foot shifiting ect...

E85 is a different kind of fuel for your car. It is 85% ethanol and 15% gasoline. It will provide big gains in power (but only when accompanied with a tune, you can buy a tune from any number of tuners, @Visconti and @FA20Club.com are two that I use and would recommend.).

There are downsides though, in cold weather when the car has been sitting for 5-6 hours it can be difficult to start the car.

edit: fixed brainfart.

Christmas noob. Lol jk

You might start with the wikipedia entry for E85.

Hey, we were all new once. :D

Uh, minor correction. E85 is up to 85% Ethanol(98% Ethanol with a denaturant) and 15% low octane Gasoline. The blend changes with the seasons in your area. For example, "winter" blend is 70% Ethanol, 30% Gasoline. There's even a schedule for when they change depending on region.

Cold starting is not as good as Gasoline but it depends on the tune with E85. If you live in a really cold climate, you could use a block heater or just add some more gasoline to the blend.

err, i meant to type gas, no clue why i typed alcohol. sorry about that.

Do we need new injectors or any additional internals to run e85, other than a tune? Say when the unichip comes out with an e85 map, will I need to add parts to the car or will the tune map take care of everything? Although I'm a Cornhusker fan, I know nothing about this corn gas shit :)

Not necessarily, but possibly yes if your tune/upgrades require significantly more fuel than the stock injectors can deliver. Research E85 threads for exactly what prople have had to do at different tuning stages/goals. E85 is higher octane so it's easier to tune more aggressively, but it requires a richer ratio to air, so it requires more fuel delivery.

On the frs / brz application. I believe you can use e85. Without any modification. You just have to get a tune. Make sure e85. Is available on your area as well. The only downside is less fuel economy and limited supplier

You can run E85 on the stock fuel system if you stay N/A. You only need to upgrade injectors if you go force induction and want to run E85.

I was always wondering, what happens if you travel (take road trips) and cant find a supplier? Are you just fucked?

e85 = $3.09 (iowa) = whp gain = ftw

With Ecutek and two maps, one for pump and one for e85, you can utilize map switching to switch back to a pump map once you are almost completely dry on e85 (and vice versa). Flex fuel sensor, harness, map (again Ecutek) makes this much easier by eliminating map switching altogether (although you can still implement map switching for other uses/features). It will dynamically adjust based on ethanol content (as seen by the sensor). In other words, with ff you can mix and match pump and e85 as you see fit.

Not necessarily on the injector part. Upgraded injectors become a requirement once your boost levels reach a certain point. E85 is certainly possible with low/moderate boost and stock injectors.
