I've recently swapped my 2nzfe to 1nzfe.....but the ECU is still the 2nzfe's....i didn't have the time to sort out the wiring of the car.......so far the car is running good....except the car is idling rough, i wanna knw if the ECU can be swapped without any wiring work, like if its a plug and play thing.....though i have the U440 transmission......1nzfe's have the U340 transmission.......need expert opinion
