Ecu WRX 2000 JDM

Postby feelsti » Mon Apr 30, 2012 9:49 am

Sorry for my bad english.
do not delete this post please, I understand very little English, and I find it hard to find information via search.
My name is Roman, i am from Russia.
I take Imoreza WRX Wagon from Japan (GGA-003042) right-handed/
Them i am install some goods (blow-off, exchaust,fuel pump walbro and more litle upgrades)
After that my car was going worse, I think that the mixture has become oversaturated with air. Poor mixture.
In my country, only three places do chip tuning, and all three places are very far from me.
I decided to try it yourself but the Russian-language forums, so there is no information.
If you tell me step by step what should I do, I'll be very good.

If your blow-off valve does not return the air back to the intake piping, this could be your issue.

If you have changed piping where MAF sensor mounts, this could also be your issue.

Change these back and tell us what happens.

Also: Your English is quite good, do not worry about it.

Yes, my blow-off valve produces a cool sound, dropping the air out :)
but as far as I know, it threatens only to enrich the fuel mixture. When I let go of the accelerator, I hear clapping in the catalyst.

No. I changed only the portion of the exhaust, which, after the sensor. I think it's called the middle pipe and low part (pipe and drum loud at the end of). All sensor still there, like in factory.
Wiretap wrote:Change these back and tell us what happens.

I recently replaced the blow-off valve to the standard plant, which sends the air back into the intake. The car did not go better. I think the problem in the exhaust.
If I understand the theory, such an exhaust, which I did not create obstacles to the removal of gases from the engine, as did the standard factory silencer. As a result, the turbine is spinning more, and the mixture obtained is rich in oxygen.
You still think that I was not going to help edit the firmware ECU?

If the blow-off valve is not staying shut under vacuum it will run lean.

The MAF sensor is in the intake, not exhaust

MAF sensor:

Changing the exhaust should not cause the leaning, We have lots of JDM cars here and do not have such a problem.

I just checked it out, I wore a condom on the valve to make sure that no air pulls when not needed.
The condom is inflated at the flies away to an unknown destination soon as I let go of the accelerator, raising up to 6000 RPM.
MAF sensor, I have not touched, looked at your photo. As much as I did not set the cold intake (in Russia we call this filter is zero resistance). MAF sensor is then left in place.
I think it's because of the exhaust, because I began to notice a decrease in power just after installing a new exhaust.
So you think that it is not in the firmware?
So I can install the tuned parts and not worry about the firmware?
Or do I still need to flash?
I was planning to put a turbine Garrett, and now I do not know but is it worth. Suddenly everything becomes even worse: (

It sounds like you may have a mechanical issue. You CAN tune out the issue, but if it's mechanical you're better to get rid of that first so you can take best power.

Do you think the problem in the valve?
I have another one, brand new valve is not HKS. I'll put it and write you changed anything.
Maybe I need some kind of production equipment for testing?
Sensor readings mixture, exhaust temperature, pressure turbine? Or is it too much?

If you have the factory valve, and that doesn't fix it, then it won't be the valve.

All turbo cars should have a Boost gauge, your car should be producing 1.1-1.3 bar of boost.

If you decide to tune it, many places will do tuning over the internet.

Yes, I was the factory valve, and I installed the exhaust. After installation, the exhaust has to pull the worst ....
What i need to edit ECU firmware?

You will need an OpenPort adapter and a WRX02 flashblock connector.

You will need the latest ECUFlash software and definitions from romraider.com

It will work. In the USA they were only 01-02, in Japan they were 00-02. Americans don't believe there are differences, but it will work.
