no CEL = you pass emission
Settle down, I did use the search button. It hasn't been discussed specifically to Washington State. Maybe you don't know, but emissions testing DOES change state-to-state; don't make an ass out of yourself for pointless comments.
Also, I understand that you need a tune to not throw a CEL. The problem is that AP only tunes when it is plugged in. That means, not plugged in=CEL. And during the test, if they plug in through the OBD-II, I cannot have the AP plugged in simultaneously.
