Is the ECU (Electronic Control Unit) for a 2005 Kia Rio compatible with the ECU from a 2005 Kia Amanti?

I'm need to install a new ECU for my 05 Amanti and I'm trying to see if these two are compatible. The dealer wants over $900 for the part alone. Better question: Are all ECUs for 2005 Kia's and Hyundai's compatible?|||NO
