Andrew, AFAIK a T5 ECU is a T5 ECU, but the programming is different for different vehicles. I've also been told the the flash chips in later T5s are write protected in some way but this only makes it a little more awkward when re-programming them. I can't give you a straight answer on whether or not you would need to have a replacement ECU re-programmed. If it was from a similar specification car/engine then I suspect not. I believe that people have succesfully plugged 200bhp ECUs into their 175bhp cars, though I somehow doubt however that SAAB would tell you that this is even possible.
