98 Corvette M6 JET DST TUNING FILE

[Lextech]

I have the Jet software and I didn't have any problems uploading a .bin to it, the only problem, is that you can't save back to a .bin, only a .jcl.

Uploading a .bin isn't the issue. You can't open a .bin straight away. You need to open a .cal (Tunercat) or a .jcl (JET) before you can open a .bin. You are right, you can't edit a .bin and then hit save and it still be a .bin. It will become a .cal or .jcl

However,you can convert a .cal to a bin.
AJ has done it for me before,iirc it simply adds the VIN as a header or something similar.
I haven't checked in compare but if you open in hex the first thing in the .cal you'll see is the VIN.
I've never had an issue opening,saving or programming .bins that I can think of.
Though other than downloading them to archive I always just work with them as .cal .
An easy way to change from .cal to .bin should be just upload .cal to a pcm on bench harness then download as .bin using the test function in TC ?
