Default Resetting ECU before California Smog Test

Hello All,

I have a smog test coming up. I put my stock downpipe back on and removed my Cobb AP (revert to stock).

I have read that the ECU will need time to completely reset its self and be in a "ready" state. If I take it to be smogged before then I will fail when they plug into the OBDII port.

Is this true? How long does it take to reset? Can I speed up this process?
