I have been looking into this lately and it looks like the best option is to block the hole in the A2A plate and mill the bridge out see pic outlined in red and a little of the bypass tube

this will allow the air to recirculate but it must pass through the cooler to get to the motor.

Do you think that moving the maf to the cool side and installing some kind of external IAC to just before the maf in the new location would help????
that or either convert to fly by wire and have 2 throttle body's. who is up for writing that code....
That's exactly what I mean... :) That's how I did my first A2A maf tune all those years ago.

Also idle hunts pretty bad when in N or P

cammed though
there is no reason why it should be like that. I did my first cammed A2A L67 6years ago and it took more time than usual but it behaves like a stocker and still runs the exact same 1/4 and power today as it did back when we first tuned it. It lives a hard life too ha ha
