Fixing Checksum in UG2 on PS2

[xWIZZLEx]

Okay everyone. I have figured out how to get an uncompressed PS2 save to my computer without using AR. Now I know where to put the new hex values for the ECU and Turbo, but when I go to load it on the actual game in loading the profile it starts to read the profile then it says that some of the data is corrupted. I know that some of you have hexxed PS2 and the PC. The problem I think I'm having is that my checksum is not being recalculated. Can anyone help me? Thanks.
