Have you considered seeing if you can get a decent tune with the stock ECU? I know the Hydra has a boatload of features, but does the stocker offer any safety over the Hydra?

Oh yeah, you have STI heads now and the '02 ECU doesn't know about AVCS.... That is the primary reason you switched, isn't it?

It is probably worth a bit more effort to get a slightly more usable tune that includes open loop on the stocker anyway for smog season and such. just a thought. At least log your closed loop stuff and get the intake map worked out. I don't know if that map translates to the Hydra, but getting a good intake map is pretty critical IMHO.
