Print Page - ME7 Checksums for 95040 bins

CAR: 2002 Audi TT 225 AMU ECU#8N0906018AN

I have played around with Turboat's python script for the "EEPROMTool." And while alot of his code works, there are a lot of "Magic Numbers" in the code. Normally this would be declared constants in some sort of documentation, but I can't find any documentation for the data stored here. I'd love to know where he got the original information to write the code in the first place.

His tool states my checksum is bad on my stock bin. Here is a dump of my bin file, the X's represent lines that do not follow the "FFFF - (LineNumber - 1) - SumOfBytes." This lines up with Turboat's noCheckSumPages and backupPage listing. Except for line 14 (two X's at the end). This doesn't seem to be a problem with his tool as line 14 in a different bin (from a thread comparing immo on vs immo off bins) happens too have the ECU Number stored and is checksummed. Is there a way to determine which lines need to be checksumed vs not or backed up. Where did these magic numbers come from?
