This graph says all that needs to be said about the OE tune, the on-set of boost and the lag in the system coming out of closed-loop to fatten up the fuel.

Nice.

Moogatwo, Sorry for loss. That stock map you ran has a very large jump in timing at 6K and that might have got ya...

Thanks Clark. Your tune was great. It's been below zero to twenty degrees the past month in Chicago, so I'm not sure it's worth it to tune at the moment. I don't want to datalog in this weather. Although I suppose I could always just use a COBB LWG Map until it warms up in spring.

At this point I'm not super worried about my warranty, because it's probably gone. I can't imagine getting anymore warranty work done given my engine blew at 5.7k miles on a brand new car. If anything else engine related goes I'm certain an SOA engineer will be brought in to scrutinize my ECU.

I'd say "I should have bought an EVO" but I do not want an EVO! I test drove both and prefer the Subaru. And even then I'd just be swapping engine weaknesses for transmission weaknesses.

We have no idea.

Take some logs and send them to your tuner. He will obviously know more than we will and can probably make some adjustments to the tune.

A datalog won't directly indicate if something is failing on the engine but it will give some good insight as to what is going on, especially to your tuner. Send the logs to your tuner and see what he says.

How much knock are you seeing? Is it at a consistent RPM every time?

If you are really that concerned with it, go get a compression/leak down test. That's the only way you will know with certainty that your motor is healthy or on its way out. But I think this would be jumping the gun. Talk to your tuner.

Clark will say the same thing as above. The Internet can only tell you so much. As above, email and work with your tuner, a log can only tell you so much. The only way to know what is mechanically wrong with an engine is a physical test. Compression and leak down will give you first hand knowledge where your engine is at.

Anything you are asking here is pure speculation. Best thing you can do is save up for the worst case scenario.

Yeah... If its making noise, I would not drive it. Really, I would need to hear what noise it is before I could give any solid advice, Could be a noisy cam bucket, Or a failed tensioner. Its also possible its a rod bearing. Lots of 2013's failed with rod bearing issues. Most of which I believe are the result of a E-tuner. Light load knock will trash your bearings quick and that tuners map had 10 full degrees added over a stock timing map so the car is over advanced as you just drive to work and cruise knocking the hell out of the bearings.

There are lots of causes guys but the main thing is that the pistons are weak and anything out of the norm can damage them.

I have a 2011 STI with 43,000 miles on it. Have gone through one turbo ( warranty) and now a new short block ( warranty). I have not tuned or modify in anyway. I also have change oil every 3,000. ? Not happy with 2011 STI.

I have a 2012 WRX and I too just had my short block and all of its components replaced due to engine knock at 20,500 miles. Now I'm 100 miles into the "break-in period" any suggestions other than a tune? After having an XT blow and now my WRX I wouldn't even think about voiding my warranty.

Reading the graph above, I think the only solution would be to change your driving style. Stay out of high load low RPM situations. Only go WOT until you know the fuel will take care of the engine...around 4K rpm, and use a decent oil.

I'm personally willing to gamble, and flash a better tune to try to preserve my motor, because I feel that is the reason for the failures. I figure if stuff breaks that would have been covered under warranty, I'll just replace it with good aftermarket stuff. Sure, I could get burned and have to replace a shortblock at my own cost ... but I promise you the shortblock I put in there will not blow up at stage 2 . If cash is tight for you, and you need that warranty, then stay stock. Just keep in mind that at 60k, the warranty is gone regardless .. I simply refuse to worry about it or worry about "oh what if Subaru denies my claim" .... I say screw em, I'll deal with it myself and replace broken stuff with better stuff. edit: Forgot to add ... based on what I said above, here is my advice. Ask Subaru if they would replace the pistons and rods in the new shortblock prior to install with some forged ones you will provide. They may allow this, but will tell you that it will then void your warranty ... but DO IT. You will likely have to pay for the pistons and rods yourself, but this is your opportunity to never worry about ringlands again, or have to pay for the labor of install. Just my 2 cents.
I will have agree with you 100% I got my stage 1 tune at 2k miles and I felt big diff in power and my mpg actually got better!! I currently have a stage 2 tune and I hit around 20psi everyday and no problems nothing at all runs smooth just don't keep it at high rpms for too long. Dealer did void my warrenty at 22kmiles but idc lol car runs good

I'd be curious to see if Cobb has run any of these stock tune AFR/Boost graphs on the newer (12,13 or 14) STI's. Didn't the factory send down a flash a couple times after the 11MY?

I am back. Only to report how the car is going AFTER I sold it. The next owner is still getting terrible gas mileage and chewing up the tires. However he is beyond happy with it. Even though it gets the fuel economy of a dodge ram it is running perfectly. I am only following up to let anyone know how this went. I personally think most people on this forum are fantastic, wonderful even . But thanks to the complete jerk offs that just want to argue and start fights I haven't logged in in over a year. So for any of you that read this thread and actually contributed in a positive manner. Thank you. People may even learn form this. for all you others, kill yourself. No ONE joins an enthusiast forum to be called names and have some keyboard tough guy run their mouth. The STI is a overpriced disaster in stock form. SOA lost me forever ... I would rather buy a used Audi S4 . And I did . I bought a used 2010 S4 with 79,000 miles on the clock . I just hit 100,000 miles with ZERO tune issues. I have invested a pair of tires, $300 worth of bushings and $130.00 in gaskets and head cover bolts since I have owned it. I get 21-28 MPG .. and its beats the pants of a STI... in every category except steering feedback . In that department the STI is a complete dream. Have fun with your rattling panels, dog **** interior , pretend fender vents and your book shelf sized " wing " ..... oh an who could forget cylinder 3 ?

I think the problem cylendars are generally #'s 2 and 4. Enjoy the Audi, but Scotty's right... that thing is going to turn into a much bigger money pit than the STi.

This ^^^. This is coming from a reformed idiot/former Audi Tech. If you got a Turbo model, have fun woth those KO3's... they leak more oil than a 2 stroke Detroit Diesel.

You went from mechanical nightmare to electrical nightmare...
