Evo 7 ECU In Evo 4

[boothy-]

Hi everyone I've just purchased a e7 ecu to go in my e4, Can anyone tell me what is needed to do to get it to work. Model number is: MR560648 will there be a immobiliser on it? Is it easy enough to disable and what wire do I need to swap
I already have 560cc injectors
Walbro fuel pump
Many thanks Sy
