Default JDM AVCS Heads which ECU?

Hello all,

A few weeks ago I was driving my Bugeye pretty hard and all of the sudden it felt like a cylinder was just dead. I feared for the worst at this point because I also smelled some absolutely terribly burnt oil.

Luckily I was going down the road to get back to my buddies place. So I limp it there. I pull in his driveway and the car just dies. I pop the hood and there is smoke coming from my airbox, I pull the oil cap off and smoke just POURS out.

Anyway, I knew this would probably happen sooner or later as the stock motor had 166k on it. Luckily I was already piecing together parts for a 2.1l stroker.

That is just the back story for anyone who wondered, below is a picture of piston #4 when I pulled it out:



Now on to the question. I acquired a pair of JDM WRX heads (with dual AVCS). I know I have to get a JDM ECU to control the AVCS, my question is will I have to get an STI ecu (v7 or v8) or has anybody used a JDM WRX ECU before. I don't want to get a WRX ECU if there are no definitions for it, as then I wouldn't be able to get it tuned.

Any further insight would be greatly appreciated!

Excuse me for not clarifying, I only plan on using the intake avcs. It was just cheaper for me to get WRX heads with dual AVCS over EJ207 heads, which is why I went the WRX route.
