Default AccessPORT stage 1 failed OBD II emissions test!

My lightly modified WRX (Cobb catback, K & N air filter) flunked PA state emissions testing today. I last flashed the ECU with the stage 1 93 octane v1.18 map on 11/15/04. 1634 miles later, the test flunked “OBD readiness” and “OBD I/M check”. This is all the data I have from the failed test.

I unmarried the AP from the ECU, drove about 30 miles and then successfully retested.

I was planning on going to stage 2 with a downpipe and uppipe … now I’m not so sure. I plan on calling Cobb later today.

What could have happened? Anyone else from PA have problems?
