newbie to this as you can tell from many questions.

Pulled a bin file from a junkyard PCM with pcmhammer, 088 OS, looks like it is from an F body.
Downloaded both tunerpro and tunerpro RT
Downloaded the 088 XDF file
Downloaded the 512 OS checksum file and placed in Documents/Tuner Pro files/Plugins (I had to create the plugins folder, it was not there)

I can read the bin file with both tuner pro and tuner pro RT, tables look correct. I can make changes.

When saving the bin I have no faults when using tuner pro RT, however with regular tuner pro I get a checksum error.

Any ideas?
