Wiring AEM to OEM ECU SD on US cars
Can anyone give some help on US Evo wiring/AEM/SD to this gentleman? I don't know the answer as I haven't played with wiring on a US car, nor with AEM.

Best to post on the forum and ask since your fellow US version owners will know.

well if i read all that right the AEM can read the stock MAP sensor, but still needs the AEM 3.5 Map sensor to run. what im curious about is that if the stock ecu is patched to run the no evap and no O2 sensor without codes and then switched to SD will the only difference in wireing would be the AEMs 3.5 sensor in addition to the stock one.... could a Evo then switch to the stock ecu from the AEM in order to pass emmisions and run decently enough to not blow it self up?? and would the stock ecu try to use the AEM 3.5 sensor??? thanks for all the help
