Default 2012 WRX with Code P0244 + Minor Overboost

Okay let me start off my saying I have a 2012 wrx with a Invidia catted downpipe, Invidia n1 street catback exhaust, Cobb SF intake, and stage 2 tune. I've been driving with this setup for about a week now. After i finished installing the mods, I went to go test them out like any normal person would do. I did a couple of WOT pulls. 1st - 3rd gear seemed to pull strong and good. After i shifted to 4th, i resumed stepping on the throttle when suddenly i felt some sort of quick brake while i was on the gas. It was as if somebody just stepped on the brakes somewhat aggressively for half a second and let go. Afterwards, my car drove fine but my dashboard was lit up with lights. My check engine light was on along with traction control plus my cruise control light was blinking. I reset my ecu and all the lights went off. I thought it was nothing but the next day i did a couple more pulls and it happened again. It only seems to happen at high speeds at WOT. I did some WOT test to see how often it happened and i'd say it happens around 40% of the time. After i noticed that this was an issue, i did some data logs hoping they would shine some light on the problem. I noticed i was overboosting a little. I called cobb and they told me that the invidia downpipes combined with the wrx's are known to boost creep. My peak boost is suppose to be at 16.5 +/-1psi and i was hitting 17.5 constantly and 18 psi at higher speeds. I reflashed my ecu with the LWG version of the map hoping it would fix my problem. Unfortunately, it didn't. My car still was overboosting a tiny bit and the strange brake at 4th gear still happened at WOT. I used the troubleshooting option on my AP and it read: P0244 Turbocharger wastegate solenoid "A" Range/performance. The overboosting doesn't seem to be to severe. What bothers me is the strange brake. After it happens my check engine/traction control/cruise control lights always light up and it gives me that code P0244 that i mentioned earlier. I actually have a data log of 4th gear when it happened and i will link it. If you noticed on Line 43 of my 4th gear pull, my boost suddenly goes down to 12.8 when the throttle position is at 100%. Can someone please interpret my logs or help me with my problems? Your help will be greatly appreciated. Thank you.

4th gear pull: https://docs.google.com/spreadsheet/...iUUVYZ3c#gid=0

Heres 3rd & 2nd gear if your interested. These gears feel like they are working fine but i am unsure whether they are running they way they're suppose to.

when you felt the car slow down you probably hit fuel control limit.
as for the 17.5 psi boost that doesn't seem to be too high...i'm hitting 17.2 with stage 1 Normal waste gate (Detroit sea level area) and I have been running it for 10k+ miles on my 11.

I think you are ok, the way you are. you do have some fine knock learning, but it doesn't seem to be too bad. Wait and see what COBB responds with, as they know a lot more then me when it comes to this.

Well i was having the same problem with mine as well and but i was hitting 19-20psi even on the LWG maps from cobb and after speaking with a bunch of fellow wrx owners in my area they all told me the same thing "take the intake off" and sure enough i took it off and everything ran GREAT!

Also you can't really go off 4th-5th gear pulls I'd ALWAYS saw high boost if i tried a low rpm high gear up it sucks but it's something i learned to live with it.

You have a TB Boost Error of -2.x you are over boosting, check your injector duty cycles. You might be maxing them out. But that over boosting is bad.

I noticed that other people are getting this code after they hit a fuel cut. That's probably what happen to me. I think overboosting is what is causing this. Will a protune fix my problems? Is it safe to run my car as is?

Try the LWG map, if not get a pro tune I have the LWG map on mine for winter then NWG for summer.

The Op is fine. When he overboosted he was in fourth gear where the 2.5 liter wrx's are prone to overboost when WOT in higher gears. His third gear pull isn't over boosting outside of the acceptable parameters according to Cobb's notes. I'd leave it be. There's no real need to to WOT in fourth anyway on the street.

OP just don't got WOT in 4th for long. Go wot until you see it start to creep, and then let out a little to keep it around target boost.

Are you running the Stage 2+SF as your Reflash map? Also, what octane level map are you running?

Yes I'm running the Stage 2 + SF intake ACN 91. I have used both LWG and Normal version and the fuel cut still occurs.

Can you try changing your map o Economy mode and take a datalog? I'd like to see what kind of peak boost level you hit then.

Okay i did a realtime flash to economy and took some Data Logs
4th Gear pull - https://docs.google.com/spreadsheet/...hS0hSZWc#gid=0
3rd Gear pull - https://docs.google.com/spreadsheet/...KTVRSM0E#gid=0
2nd Gear pull - https://docs.google.com/spreadsheet/...EZlVHM3c#gid=0

By the way, the data logs from my first post were with the stage 2 + SF intake LWG map. That is the map I'm currently using to daily drive.

I also did a realtime flash to the regular Stage 2 + SF intake map and took some data logs so you can see the difference. I looks like my boost is higher with this map. I hit the fuel cut on 4th gear at line 38 if you notice.

The boost on the Economy Mode map is creeping much higher than it should be. We have seen in some rare circumstances that some 2011 or 2012 vehicles have a very hard time controlling boost due to small mechanical differences with higher flowing parts.

First, I would recommend reverting to the stock intake to see if this helps with your boost control. Then, we can look at another log to see how the car runs.

I love how the intake sounds though. Is there any way to possibly fix this issue without removing any of my parts? I heard people say that a protune could fix it or porting the wastegate could also help. Also, is the safe to run my car as is?

Log your injector duty cycle if you can, we'll see how your fuel side is doing. I also suggest removing the intake to try to isolate your problem, but do this after you log your injector duty cycle with the SF+Stage 2.

if you want to keep all your mods and never have an overboost/boost creep problem then install a EWG kit. that will eliminate your problem. boost creep is a mechanical issue that cannot be fixed by getting your car tuned. some people have luck keeping it under control with a pro tune, but a pro tune will not always eliminate the problem. it is more of a bandaid for the real problem. over boosting on the other hand could be tune related and fixed with a pro tune. remember that every car is different and a OTS map is not made speciffically for your car. also read the following link.

might help you better understand what boost creep really is.

Thanks for the advice everyone, i really appreciate it. I think I'm going to get an EWG to fix the issue. Also, is it safe to run my car right now using the LWG stage 2 map? I just plan on daily driving and maybe doing some pulls in 1 - 3 occasionally but not in 4th because thats when i hit the fuel cut usually occurs.

you can try taking off the intake for the time being until you get your EWG setup. that should help some from what i am hearing. but if you do keep everything on the car and keep it the way it is, i wouldnt push the car at all. daily driving you should be fine but keep off the go pedal as much as possible.

i would always rather be safe then sorry. an engine is an expensive thing to replace.

I had the same problem. The OEM ebcs can't handle the high boost so it throws a fuel cut to protect the engine and not to over boost ... try getting the Grimmspeed ebcs and protune

Just wondering OP, did you ever try using Cobb OTS Severe LWG Stage 2 + SF map to see if it helped? What did you end up doing? EWG kit or Protune with a aftermarket EBCS?

Default how to solve over boosting on 2012 wrx

all right you have 3 options i had this very same problem

1 try cobs saveear low waist gate map

2 buy cobbs external waist gate witch is 700 dollars and you will need a tune so thats another 400 so there 1200 down the drain but it will stop it from over boosting thats a guaranty

3 or you could do what i did and take off the intake that solved my problems
lol i was overboosting bad i made 23 psi once

i know this is old but yes! this should be a sticky cause if you lift a bit it wont overboost.
