From my research, the 1.8 cruze and the 1.6 aveo (manual transmission) are interchangeable. Like if you buy a used ecu for either car its the "same" part exchange number. That doesn't mean there is no other issues with running one, but looking at them, the plugs match up, the tune looks the same. But I can't speak for immobilizer issues or anything else associated with switching ecus.
