Hello everyone! Been a long time since I have been here, looks as though my post count was reset and most of the projects I was watching are all but gone...
Either way I am here for some info from the knowledgeable.
My Car: USDM 03 WRX
The end of my motor: Bad tune + time = broken ring land
What I got: A JDM Ej205 ODB2 motor with less than 35k
Now before everyone starts posting about how I should have just gotten a 207 or just did a hybrid, or a v8 spec C cause there semi closed and better and yada yada I didn’t. This is the plan for the time being eventually I will pick up a blank 2.5 and start the long process of a super build, but that will be a long process and would like to be able to just cruise around in my car while that is happening. Back on track!
What I think I Know:
I need a JDM V7 of V8 ECU to control the AVCS (also a wiring kit, got that all covered)
Conflicting information on if these ECU’s will talk correctly to the US ODB2 plug in (Smog, I know Cobb doesn't support JDM)
My stock ECU will work but AVCS will not and from what I have heard, if it’s there don’t waste it because AVCS makes a nice difference!
So here are the questions:
Motor is JDM ODBII with AVCS. Ok I need a V7 or V8 JDM ECU to run the AVCS system now the question is V7 or V8 JDM WRX only? Will either of these support ODB2?
Are there other options for ECUs? Forester? STI? (Are they all drive by wire?)
I am just having issues finding capabilities with ECU’s
If I can find a damn V7 or V8 and they do not support ODB2 I presume I could get my car fully tuned on the JDM so I can take advantage of AVCS and have a base tune done on my USDM for smog purposes, (TGV CELS pulled and compensate for the new compression etc) but obviously I would enjoy a simpler route.
For the closing information on stuff that affects the motor here:
Cobb high flow down pipe 3” to back
Perrin fuel rails
Over kill injectors
Over sized top mount intercooler
ACT clutch lightened flywheel
So any information on what I can do here would be awesome, I know there are a million other things that I “Should have done” but we will save that for my new future thread on my monster build at that time I will be sourcing tons of information. For now I’m looking for what I can do with what I got.
