I went to Tunerpro.net and downloaded TunerPro RT again. I'm still getting the checksum error. Where do I find the dll? I loaded an older version of TunerPro and didn't have the error.
I have a matched pair of XDF and Bin OS IDs.

I loaded a 2004 Corvette 4L60e Bin on a P59. Removed VATs and some DTCs. I'm going to test it on a different 2003 Tahoe to make sure it works. The donor vehicle was also a 2003 Tahoe.
