I agree with MikeR, I would think it would be just a drop in since all the factory electronic components are the same from ( stock ) engine to engine you dont have to relearn a cps, a new fuel injector, a throttle body, a new iat sensor, or any thing else you would replace if it had failed and match it to your ecu. I have never heard of the ecu being vin matched to the motor other than being matched to the original design functions of the cars particular electronics, as in like a V8 ecu v/s a V6 ecu.
