Default Code P0244

My setup. Helix Catless Downpipe, Greddy Evo2. I also have the AP Stage 2, 93oct map.

On the highway, I was playing around so at gear 6, at about 2.5 RPM, I floor the gas.. At about 3.5 RPM, I heard a loud bang and the car jerk. Then the Engine light is on.

I check with my AP the problem and its Code P0244. According to the manual, P0244 is "Turbo Wastegate Selenoid "A" Range/Performance". Now, I got no idea what the hell is that and what really causes the problem. I am facing some boost spike issue?

What do you guys think?

Kinda OT, but if you go WOT in 6th gear it causes a lot of load on the engine.

Actuaully I don't think it off topic. You should have downshifted to 5th or 4th. The amount of load you are puuting onthe engine is no good. I flashed the same code after loading my car in 5th. The code has to do with boost spike. On STIs nd the 06 wrx when running a catless setup the wastegate can't do its job properly and let all of the air out. The little bit of air that s left in the turbo keeps spinning the turbine and casues it to overboost. You can do 2 things about it.
1. Port the wastegate (which i am not sure will completely fix the problem)
2. Drive around it

I am in no way completely knoledgeable on this but i explained it to you as it was explained to me. Hope it helps. If you search you can find a ton of threads on it.

+1..... what did the boost guage do? it could just be the load on the engine. ive heard these cars dont like top gear WOT runs from a low rpm.

I am just testing the turbo psi and make sure its ok so got to put a heavy load on the car. Well, COBB release a firmware with lower wastegate and I am sure not if that will help to solve the problem

I think for certain models cobb has released a lwg map and it has helped. I am not sure if there is one for your car or not. Unfortuantly i get boost spike and there is no lwg map for my speciffic car.

chaddeus, I thought you were in Lafayette.

If you like, maybe we could link up this weekend.

Also, +1 to what Scotty said.

Actually that's not entirely correct. I know it's been beaten dead over and over again on how an STI with turboback exhaust will boost spike, but a ported wastegate is not the only answer to this problem. In the end the problem does not surface unless you're pushing the flow characteristics of the stock turbo and expecting a lot of power from it.

Example... Dynocomp Stage 2 Flashed 04 STI with APS 3" Turboback exhaust. No problems with loading the car in any gear... including 6th. Car put out about 280 and 300 to the wheels on DD Road Dyno. (Slightly higher on a real Dynojet.) Same car dynotuned and pushed to the limit to arround 320 and 350... had spike issues in 4th and above gears... SUCKED! It's all in the tune my friends.... everyone likes to argue otherwise, but I know what I've seen and what I have datalogged.

This is just food for thought... that's all.

I have the same problem in my sti. The LWG maps will prevent this from happening. I thought it was boost creep... But I have never seen the boost go above .12 Mpa. I have never had it happen that low in the rpm range. It usually occurs at about 5000 rpms. The other day the outside temp was 60 deg. and it happened... Im hoping a pro tune helps. I am running a full helix catless set up.

It's boost creep and it isn't because of a 'spike' because the over-boost condition needs to last for at least two seconds to trigger that DTC.

Has anyone experienced the CEL code p0244 without any mods other than a turboback. I have an 05 STi. I topped 4th gear, shifted to 5th and then got the CEL. TIA

Any tune that isn't mapped correctly to keep EGTs and boost in check enough to allow you to go WOT whenever you damn well please is a poor one. There should be no problem with a proper map with going WOT in any gear from any RPM, so long as you're not lugging the engine (ie, below 1500 RPM).

Reasonably tuned cars don't have any issue with using WOT whenever the hell you want in whichever gear you feel like.

.....stock.....they can and HAVE had issues...a poor tune(and many are) and ya got issues.

Turbo'd engines should NOT be deiven in such a manner as to cause issues and going WOT in top gear, especially if it is a WAY OD gear like WE have, is just NOT a good idea unless the vehicle is at speed for that gear.

Period.

conclusion: its in the tune rather than the hardware itself right? Bad tune, problems. Good tune, no problems.

So now, is the AP being tuned badly? With my stock ECU, catless DP and Greddy Evo2, I can WOT at anytime I want and never had any problem until I switch "upgrade my ECU.

Its just the load on the motor. Boost is almost entirely dictated by load. The higher gear typically the more load; ths is why you don't need lose to WOT to give youfull boost in that situation. Its normal...

To think about it, I am not having problem putting the motor at high load with the stock setup. So when suggesting not to put your car into high load seems not too convincing. Its like telling others to drive their car gently forever because any load will shorten the lifespan of the motor (although its arguable how short it will be).

Rather than blaming the driver, I think its more about the setup.

.....it is about NOT doing something WRONG and then crying about the results.

Downshifting the car is the RIGHT thing to do....the difference between a GOOD driver and John Q. Stoopid
