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
quick bump, ill be converting to AEM this winter. but for when i go back to the stock ecu for inspection purposes, when i wire in the white wire to pin #76 to convert the front o2, will that wire, when its wired in mess with the stock ecu and throw a code?

good question bro, I took out the meth kit this weekend and the wiring was crazy, I got the stoc ECU but the car is still all apart it will be interesting to see how this all works out
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.
