I have a F23A Accord, if I were to swap the J35A from the Odyssey, what ECU do I use so it can pass smog? In my state they only do the OBD2 check, but what info does the OBD2 port actually send? If I were to use the ECU from t he Odyssey, would they be able to tell I have a different engine (technically that's from a truct so it's illegal)? Should I use the Accord V6 ECU then use piggyback to tune it so it'll run with the J35A engine? Thanks.
