AEM EMS to Stock?
I am about to under go this painful procedure, and I hope someone else has done it so they can maybe give me some pointers. I know the ECU part is easy but all the extra wiring maybe I dont know. Is it capable to even do this?

so pretty much you just need to convert the map sensor back to the stock one, if you are running a aftermarket map. i imagine you are? and hope that whoever installed it did not cut the plugs off for the stock map... and then the iat sensor is tapped into the mas air-flow harness ... remove iat sensor and repair exposed wires

ive been thinking about it and i think i got it figured out.
when u put the stock ecu back in to go get inspected real quick. put your stock ecu and sensors back in obviously. but just disconnect the wideband (uego, where the sensor meets the harness) and just leave it off to the side and go get inspected. it shouldnt read anything then and that wire thats tapped into the harness shouldnt even affect it since it will solely be reading off of your front 02 only.
