Need to smog my car here coming up. Car is mostly stock other then inlets and muffler delete. Been planing on just uninstalling the access port before smog however I Updated the software on the AP3 since upload and hope it hasn't lost my stock file (Stupid I know). So in my searching online I came across this document.

Wondering if anyone has seen or used this?
