1. high compression motors will pre-ignite with low octane gas. This is not a pre-ignition that you can tune out with ignition, since it is auto-ignition.

you may be able to adjust the dynamic compression of the motor to be lower in a problematic area via AVCS tuning.

2. Ethanol content varies widely.

Unless you have an ethanol content sensor, give up life on blending. e85 around these parts is cut with 87 octane. This means that if you BELIEVE you're getting e85 but actually get 50% ethanol content, the other 50% is 87 octane, lowering your rating much more than expected when you use bro-math to make e50.

3. Parts don't cause problems unless they are literally broken. Tuners blaming parts are inexperienced with the part and/or do not want to spend the time on an obscure set up. ROI is too low. A good tuner will understand how ROI works and will choose to recommend parts to you. This doesn't make the parts bad, this doesn't make the tuner bad. It makes your life easy if you listen. It makes your life hard where you get to spread misinformation on a forum because you decided you were smarter than the person you are paying to tune your car.

4. personal opinion, I wouldn't run ethanol at all on the FA. Nobody will recommend full e85 ever. It's not because power can't be made and it's not because the internals can't handle it. The HPFP can't deal with it. Why? I don't know fully. I just know "don't do it if it hurts"

If I was looking for a clean power adder and wanted to reduce the complicated bro-math ****ery that is annoying as ****, I would run meth inject and 93. Added benefit of lower charge temp, increase in octane, and keeps joo valves clean (to quote someone great).

Thats because I've owned mine since 2014 jackass and AEM was the only option, plus I worked for them so I have no issues with it unlike someone in here with their GS trash LOL

Get out of here. You're spreading nonsense. EJ's can be tuned within like 4 dyno pulls even on some crazy set ups. Just does not translate, sorry.



Calls GS trash, has AEM CAI and DEPO down pipe....

Got damn this forum is great some times.

Lol I know, He had a GS Verticooler on his 400hp wrx before it got t-boned. Del tuning Flex before COBB came out with their Continental sensor with 400% markup :]

You can't tune that out because you can't tune out stupid driving

And the knock sensors don't hear it....

Yes open box makes for a very consistent MAF scale...


Good you've had your car a while so you should know better

Wow you are such a pro physicist , NOT. With the hood closed its essentially a closed box...
and the Data shows otherwise. Where did you study physics again? Ronald McDonald University? Fyi an MAF works by heating an element to a Constant Temp and measuring the amount of Voltage required to keep that Temperature. Temperature is related to Pressure, Entropy, and Volume, but I wont get into that fully, yet thats your next Lesson. I suggest you read a bit about Continuity equations if you don't want to be a pleb and learn how to integrate a Cylinder using Cylindrical Coordinates .

Yep. Your intellect level is about on par with someone who has anti-Semitic tendencies.

11/10 would read this again.

Also do all the aftermarket charge pipes on this car fit like crap and come loose randomly, I feel like I see that alot.

Only one Iíve seen good things about is perrinís and even that is questionable

For the minimal gains it seems like a pretty big waste of $200-$250, especially on a stage 1 or 2 setup.

TBH, I got mine mostly for looks. Didn't feel right getting a Grimmspeed TMIC and then having that wimpy, skinny plastic stock charge pipe on there

So far mine has been snug...knock on wood.

Ok, all trolling aside, please keep in mind that knock sensors are not so trustworthy at higher rpm. The background noise increases exponentially. Also, ethanol fuel should use colder plugs than stock.

Ethanol burns cooler... If you use to cold of plugs you can run into misfire issues. On my Evo running e85 I actually had to put stock heat range plugs in!

Before doing a compression test I decided to go through and look at everything that I had ever touched under the hood to see if I could find something to attribute the false knock to. I noticed that the clearance between my Grimmspeed charge pipe and engine had gone from very tight to actually touching the engine. At high RPM/loads I think it was vibrating and making the false knock noise.

My front end got in a small fender bender a few months ago and I bet that's what did it. After I readjusted it I took the car out for some pulls....knock is completely gone. Now I need to ask Ron if we have any more room for increasing boost/timing since I found the source of the knock.

It was a stressful few days as I thought about a toasted engine.....but at the same time that would mean a new IAG block for more power down the line.
Were you getting knock on every single 3rd gear WOT pull prior to adjusting the charge pipe?

I get knock every so often, and I'm wondering if the GS charge pipe is causing it. It's also 1-2mm from touching the engine. I can try to adjust the hose clamps to add more clearance.

I have the P&L chargepipe (got it cheap; got it for looks not power) and that thing blew off more times than I can count but now that it's dialed, it fits great and hasn't come loose since. Turns out the hose clamp was bad. I had a really good experience with their customer service too as we worked through the fitment issues.
