ECU Replacement?

[badie]

G'day lads! Didn't realise this forum was still active! I have a question for you all then, I've gone to the wreckers and found a new ECU from a D22, YD25, possibly different year but same engine and car as mine so I'm not sure if that matters. Now I was wondering if it's just a plug and play kind of thing or is there something to do with the injector codes? I'm not sure, please help! I'll attach a photo of mine on the left and the new one on the right.
Thanks!

assuming common rail you will need to enter injector codes, wipe fuel pressure data and relearn throttle.
