I'll check my ecu as well.

Jubert: Please don't take this offensively, but are you sure the ecu's you have match the motor? They may be from something else.

yes, positive. I actually tried 3 different JDM ecus

a V7 limited, a regular v7, and a v8 ecu... im convinced its not my ECU. it has to be something funky with my wiring...

ok so i assume u meant this...
heres the thing... i know the 04 wrxs have this PCV connector, but i didnt think the jdm motor/hanress had it???

i didnt take the intercooler off to check, but it didnt look the same as my 04 wrx usdm setup.

I have the v7 complete engine (engine harness + ecu) and getting the CEL.
here is the pic:

^so thats the v7 motor... shouldnt the gray plug be visible in that pic?

for example, on my brothers 04 wrx, its clearly there:
see pic:

^thats the gray plug ur referring to that i need to disconnect right? well is it located in a different spot on the v7 motor?

(i just didnt want to take the tmic off to check, cus the tmic is a PITA to put back on)

Clark,
I read earlier how you said the 68HTA is a step backwards, i'm not arguing, however, I have already purchased one and it arrived yesterday. I'm curious as to why it is a bad decision, and will send it back if i am able, however, i think i am stuck with it now. Also, where can i find a good tuner for tuning my motor once i have installed all of the upgrades, I don't know of many places that will do Open source tuning.

Thanks.

The Reason i say that is performance and power. When I modify a car and tune it, I want it to make more power so the car is faster.

As for the guy with the flashing cel, You have to remember you are running an 02/03 style ECU on a 04 WRX car. The 02 does not have that sensor at all. Unplug it.

Also, even a V9 does not have this sensor, in a JDM car, although the USDM Sti 04+ have it.

Also, that info about the V9 downpipe being USDM legth is based on a one-off situation, mine is still JDM short length.

I only found on the web mention of one case of a long OEM JDM V9 downpipe and it looked like somebody had already modified it.

V9 spec C here too.
Did your downpipe come with that weird extra silencer box at it's outer end?
Mine looked normal and short. I will find out in couple hours for sure. I hope I'm wrong..

Is the thermostat for a different temperature for the JDM?
What's a normal temperature, idling in 40 degree weather?
I want to check it with the OBDII connection, to make sure what I'm running, to diagnose how healthy the engine is.

Does the Spec C get a different exhaust manifold, compared to a regular V9 Sti twinscroll?

I think it did
I ditched it the moment I got invidia DP and cut the bellmouth part of the stocker

Spec C/RA difference is blueprinting, and few other bits like cams/turbos/IAT in manifolds...

headers/uppipe is identical to normal twin scroll, which is a beautifull piece

So far I came up with:
Ra has A/C, which mine has as well.
I thought that S203, 204 have blueprinting.
Turbo is VF36, which in the FAQ is mistakenly described as "Titanium compressor", while it is Titanium Aluminide turbine and shaft.

My exhaust manifold does not have the normal metal heat shielding, but is wrapped.
I read that once you remove the shielding, the twinscroll manifold looks just like a set of headers, but I have also seen headers that were said to be "spec C copies" and had no metal shielding.
I was wondering if they ditched the shielding for weight savinds.
I know of the temp sensor in the manifold
I thought that the Sponaugle table showed that the cams were the same with the Sti, but the heads receive additional hand porting.

VF36 is not titanium, it's just BB
VF42 has the titanium shaft you are referring to, which is found on S203/4 cars

previous owner could've taken stock HS off and wrapped it (which is pointless)

cams are purely speculation, I can not know for sure
we did compare V8 RA and V9 RA cams and profiles were different

not trying to beat a dead horse- when u say 02/03 ecu i assume u mean JDM... i understand the v7 were on the bugeyes that didnt utilize the PCV. Only the 04+ did i believe... but if im running a complete v7 motor, (which shouldnt have hte PCV) how am i running into this problem? there is nothing to unplug. unless im really slow and stupid, i just dont understand... The chassis and harness is the 04 WRX. as well as the stock 5 speed. the motor, ecu, jdm harness is ALL from the 02-03 v7 spec c- so isnt the pcv (or lack thereof) PART of the JDM engine? in which case i SHOULDNT have this problem? I tried to PM you clark- but says u arent recieving...
