If you used a 165 ecu to save the file, it should've calculated the checksum
correctly. ID byte is at $0008 I believe ? Is the ID a 47 ?
If you used a 747 ECU to save the file, it would calc it wrong.
You could download the checksum program from www.tunercat.com
to check your own files...btw--wouldn't mind a copy of your stock bin--I
don't
have many of those.
