Provided the ECU is good and from the same spec of car it "shouldn't" require the involvement of a T4.
Under no circumstances connect the new ECU without bolting it in position first or it will log an accident rendering it useless.

steve. the last paragraph on your post. does this mean that the ECU needs to be earthed before connection ? is this the reason why it will wall itself .. ?
