I'm getting a lot of carbon buildup in the throttle body of my megasquirted Gen 1 2.6.

I'm wondering: does air injection still help me pass smog when I'm running a 'present day' fuel controller? I know air injection helps the cat burn off excess hydrocarbon; but I can set my fuel map to lean the burn out in the ECU.

Should I ditch it? Or fix it [I think it back-flows]? Or replace it with a new one from Mr. Bishi? Any aftermarket switched valves or snags from a boneyard that will work?
