Can't get it fixed (assuming you mean tune) if a part is broken
No i meant quit messing around and take it to a shop to have it gone over.

As if we dont all burn through enough money with subarus :P

Basically it just looks like the boost target vs actual is all wrong. theres no loose vac lines, its a stock BCS, WG seems fine. its gotta be a problem with the ****ty cobb tune rather than the hardware problem, but I might end up giving you a call this week Nick to try and swap em over and see if it helps. if it ends up just being a tune problem then that makes it easy. but why not do a little due diligence before taking it to a shop?

Right. which is why I have a WRX which is stock except a turboback and cobb stage 2.. - and it has a boost creep/overboost issue. not exactly a list of problems

Right right. An overboost can make what seems like a small problem into a catastrophic engine failure. Ask me how i know.

d3vo, your logs show that cutout is really working well and making a significant difference in boost response! But, it looks like the tune isn't meant for it since you're exceeding your boost target. Also, it looks like the boost control solenoid is responding faster than what the tune is expecting; so the maps that control this behavior need to be adjusted. Besides that, there is nothing else wrong. You can even tighten the wastegate arm some more and tune for it. I'd tighten it as much as possible.

It's an easy fix but if you don't want to tackle this yourself, PM me.

i'm working a ton but this looks pretty good to me, WRT THE BOOST. i don't see much flutter, WG is working proper in this.
IGN looks low, bouncing around, and that's a lot of KC up top. but then it's been ~ 4 years since i looked at AVCS 2.5l logs.

oh and your MAF G/sec is crazy low to my memory. looks like logs of my NA engine! hahahaha!

Thanks alot for looking at it. I posted a few more logs via google docs at the bottom of the last page.

If I do it, all I'm going to do is fix the boost oscillation while keeping existing boost targets. Nothing else will be touched.

Yeah, that TD04 doesn't have much more to give in terms of MAF g/s. But yeah, the timing curve doesn't look ideal. In the 1st log he posted, it knocked twice in the 5300RPM range. The ECU has learned almost 2 degrees of learned knock from there to redline by the 4th datalog. Thankfully the Subaru knock control system is really good and this turbo is really small.

Its conistently pulling alot of timing out the top as already mentioned and the DAM is knocked down a good bit, even with boost falling off fairly hard. The timing isan't that aggressive so it might be a little lean. I would get a wideband in the exhaust to verify AFR. The boost control is a very simple fix but you have some other tuning issues that need addressed!

When I tune a customer car with a cutout I typically make a map for open and closed as it has a large effect on boost control.

If you want, email me the COBB map you are currently running and I'll make the changes for you! :-)

You mean to replace the plastic under tray below the engine? I don't think anyone local would do that but anything is possible for the right price

Yes, my car doesn't have the plastic under tray so I might as well get something that offers a bit more protection

There are a number of products currently on the market that will do exactly what you want, that would be cheaper than a custom skid plate. Shoot us an email and I'll send you back some options and pricing.

But, if you really want we can absolutely make you a one off skid plate specifically for your car.

Make two, i need one. Keep the pattern so it's no longer a one off.

Aaaaand it's fixed. I drove the car out to TPG Tuning so nate could do a couple ride alongs to see the problem. Nate took a look at the map for me tonight and sorted out some problems. No more overboost; there was apparently a huge like 25% error with the MAF scaling causing it to basically drive like a piece of ****. Now it's sorted and so much better. - he even fixed the tune so it won't overboost with the cutout. Boom.

Thanks for the kind words Josh, and nice to see you too, it's been awhile!
