I've got a 1993 Camry XLE V6 ...engine: 3VZFE

and 1994 Camry LE V6..............engine: 1MZFE

I plan to install the 1994 engine(1MZFE) into the 1993 Camry. Do I need to take the ECU(engine computer) from 1994 Camry to 1993 Camry with the engine? or do they use the same computer?
Thanks for your response(s).
