I am using the $6E "extended" downloaded from Scott Hansen's site. The "extended" I believe if something done by the person that was working on my tune previously. He used to be a programmer in a past life. What I have in my Tuner Pro is everything that he has been tuning with.
I have been viewing stock tunes, hypertech's tune and comparing with how those flags are set and I set the Vette flags (the ARAR bin I downloaded from this site) the same way. Yet for some reason they don't seem to take.
For instance, I set the "Cooling Fan N/O Req Input" in the Vette bin to match that flag with the Camaro bin. Still, the fan comes on with the key.

The values that I changed are not outside of any limit. I took the values from one bin and used them in another. I would hit the "commit to changes" floppy disc icon in the values table. The "save bin" floppy disc near the load bin file folder and a combination of both. When I open the table again, all values were "46". NOT the value I entered.

The 1989 Camaro APYN and 1989 Corvette ARAR should both use the same XDF.
