330i Auto into 325i manual

I have a 325i manual with a blown engine. We want to switch an engine from an automatic 330i into it. If I have a doner car with the ecu and wiring harness, can I just use the ecu from the 330i or will I have to reprogram it to work properly with the manual transmission?

Simplest would be to just flash your existing DME with the 330i tune.
