For the record, e30 is about 95(r+m)/2, 94.4 precisely. Like I had said, ethanol will provide all the knock and detonation prevention, that's the point of it. I'm trying to help you goodys..

But again, you can put whatever you want in your car cuz someone said it would help, and it will if you believe it hard enough. Superstitious people are everywhere.

ADDED: on top of it being 95aki it is in practice acting as if its aki rating was much higher than that due to its cooling effect and slow burning. That's the point of running an e30 tune/fuel.

If you start with 87 Octane E10 and you add enough E85 to reach E30 you will have an effective Octane rating of 90-91.

If you start with 93 Octane E10 and you add enough E85 to reach E30 you will have an effective Octane rating 95-96.

This isn't a question of fear mongering or feeling good. It's a question of running the highest possible octane you can when putting 300-350whp.

Not all E30 is created equal.

This guys probably talking crap about me..

Repeat after me everybody, e30 aki rating is 95, but because it cools as it draws into cylinders and cuz it burns slow it is much higher in practice.

NOT open for debate. Fact.

But you are welcome to pour 91 or 93 or 94 octane to increase knock resistance...

AKI Increase // Ethanol by Volume %
1.0 - 1.5 // 5.7%
1.5 - 2.5 // 7.5%
2 - 3.5 // 10%
3 - 4.5 // 15%

ADDENDUM FOR FUN: I wish I had a source from someone phone's Instagram instead.

Why stop there? Once you have that you are more than half way to your own flex fuel kit, just need an AP and a pro tune afterwards to take full advantage of it

I'm enjoying this discussion. Lots to learn, after years of avoiding ethanol completely.

Moore's PDF indicates that the ethanol fuel's AKI depends on the base fuel it is blended with. The chart doesn't list the AKI increase of E30, but we could extrapolate (assuming it continues to be linear) and guess it adds 6-9 AKI.

Therefore it appears that a 70% base fuel (85AKI) and 30% ethanol has a final AKI of 91-94. A 70% base fuel (93AKI) and 30% ethanol has a final AKI of 97-102AKI.

If I had to take a guess I’d guess that any premixed blend is mixed with 85/87aki.

BUT you’re missing the point. Even though e30 aki may be 95, it acts as though it was much higher, like 110 (made up number, maybe higher) due to its cooling effects.

Think about The whp increase that e30 allows compared to race fuel for example, even though race fuel may have higher aki rating, e30 will give you better gains. Why do you think that is? It’s not just about the aki number.

Damn, This threads almost had a birth day

So if any of you had to do it over again from scratch what would you choose:

Cobb AP $675
Stage 2 MAP Tune: (Free With AP)
Map intake: $316
Down Pipe: $549
Total: $1540
Dyno # 310HP 330TQ

Or:
Cobb AP: $675
Map Intake: $316
Map stage 1 E30 ($150 With AP)
Total: $1141
Dyno # 320HP 334 TQ

And with the E30 Tune work with the MAP brand intake? Is there a Stage 1+ E30 Tune?

I really want to hear that turbo spooling and that awesome woosh sound that the intake help give.

The Dyno Numbers are very similar, I have E85 Access near my workplace, I am the only driver of the car,

There is a give and take in everything in life it seems,

The E30 Tune is less initial work and $400 cheaper Just Get the AP and Flash the Tune but it is more work in the long run to have to measure your E levels every time you pump, or guess and put in 4 or 5 gallons of E and hope you run right

The stage 2 91 Tune is more initial money and labor to install the intake and the down pipe Get the AP and flash the tune, and then in the long run less work to be able to just pump 91 and be on your way .....

I just picked up a 2017 WRX 6MT and am waiting for my tax return to pull the trigger on one of these options, I started my own thread and received some pretty great feedback so now its time to see what you guys in this thread have to say.

And please let me know if my numbers are off:

@ian
If I purchase the AP Stage 2 tune MAP intake and MAP down pipe can I get a fat discount I want to make decent power but stay in daily driver status....
I also plan on getting front and rear strut bars and Sway bars to tighten this thing up a little, my tires are stock Dunlops and this things got a little under steer that I don't care for

So If i buy ur intake I get the stage 1+ e30 tune for free and if I buy the AP through you I can get the stage 1 or 2 91 tune for free also I want to have the option to switch back to 91 incase I go on a roadtrip or something and e85 isnt available

Will the stage 1+ e30 tune work with a down pipe ......can I run your intake and downpipe for the stage 2 91 and then also reflash to the stage 1+ e30 tune while keeping the downpipe on

If you want some noise, do the e30 stage1+

The e30 tune alone is just an awesome bump in power. I wouldn’t bother with much else unless you really plan on getting into the engine itself.
