Not as far as I know ( but I do stand to be corrected )

You will need to let it 'learn the engine', but this can be as easy as letting the car get up to temp ( fans coming on ) whilst idling. Make sure all lights, heater fan rear demist, etc are off. I have recently read a much more complicated procedure involving running at certain revs for certain times but I've always just done the simple version when my ECU has been disconnected and it seems to work fine.-

no mate only obd2 ecus are coded it will simply plug straight in and your off but make sure it has the same part numbers on it.Carl.

Corrado VR6 of that year should be 021 906 258 AG, its not a coded ECU

PLEASE PLEASE HELP ME!!! the ecu i had on the way to me got broken in transit.breakers yard has refunded me so i need another.the problem is when the origional ecu packed up i sent it to be reconditioned and the reconditioning company said it had shorted out and would replace the parts inside the ecu for new ones. when it came back put it in the car and nothing happend at all.took it to vw who checked all the wireing and everything that end was fine.a car electrian friend opened the ecu up to find it had been bodged and there was now a hole blown in the pc board.reconditioning company wont do anything about it and i refused to pay them.sent it to another ecu reconditioning company and they said its now no longer repairable.the problem with me getting a new one is im not sure what code ecu i need as the first company took the origional bosch label off and stuck their own on. it says 0 261 200 493/4 021 906 258
