My AZ Emissions Experience. ECU Tampering
2013 Evo with intake, down pipe, stock cat, and exhaust. Cobb tune on ECU.
Failed Emissions on first go for "ECU Tampering" - Got sent to the Waiver Station where they do a whole visual inspection.
De-tuned the car to stage 0, kept out of boost and below 3000rpm to get sensors ready.
Failed 2nd attempt for "Misfire Sensor Unsupported" - It must be disabled because it came back on quick after the next step.
Uninstalled the AP. - The Emissions Readiness function still works which is great. Got the car to have everything but "EVAP" ready by driving around below 3k RPM again. They said they could test it with only one sensor Not Ready.
Took it back in an hour later and passed emissions.
