The 551 ECU is much much newer in terms of the software than the 976 ECU. It could be something like the air doser flap being given a full signal because the 976 ECU doesn't have it, or you could be in limp mode because there are some other options you don't have but that's not very likely.
If you try to put a 551 file on to the 976 ECU it WILL brick it because the 976 software only has one bank of maps and the 551 has two sets , one has 7 check sums the other has 11.
Why have you swapped the ECU, and why haven't you used the same ECU numbers? I've got all of these in stock if you're struggling to find one...
