Newb Help!

Ok, so my ecu isnt yet blocked as i havent started to play about with it yet

but, im planning on purchasing a used ECU from the same model car on ebay (Octavia VRS 1.8t)
i think its the Bosch ME7.5 ECU without looking to deep into it,

my question is, does anybody know if this will just plug in and work, as if this will work then its a good opportunity to start learning on the spare ECU without the chance of destroying my fully operational one?!

your feedback would be appreciated!

You will have to clone or remove the immo from the spare ECU only then you will be able to play with it on your car
