You quite likely don't have the checksum.DLL file required for Tuner Pro RT. Do you have the latest Tuner Pro RT version - 11 January, 2022? I think that version includes all of the correct checksum files.

Or even more likely, you edited your BIN with a mis-matched XDF file. That is a big no-no and will bodge up your BIN with checksum errors every time. Don't write that bad BIN to a PCM unless you want to manufacture yourself a wheel chock or a doorstop.

You can either fix your install of Tuner Pro RT, get the matched XDF to your BIN and start the editing from scratch or depending on how badly your BIN is messed up, a program called Universal Patcher might be able to repair it.
