There is an early mask for the turbo Sunbird which AFAIK is not supported by anyone. Mask ID is $49. The 87-89 Quad 4 mask is $5C. BCC AMDD from an 89 Quad 4 is unique as it can detect hardware differences between the 1227749 and the 1228707.

There is a known issue when trying to use $58 with an AutoProm, and maybe some other devices. The issue is to do with data logging, it just doesn't happen, and usually garbage data is displayed, if a "connection" is found.
There is a patch that can be done to the $58 bin to rectify this issue. The info I found talks about using a patch utility to add the patch to the bin, I was able to hand edit this using the hex editor in Tuner Pro RT, and work fine.
In my research, many people reported improvments in connecting with other programs and also while not using an AutoProm.

I am attaching the ALDLpatch.zip here. I simply used the Tuner Pro RT HEX editor and at the addresses indicated, changed the values to those shown in the aldlpatch.txt, contained within the zip file.
The man who says something is impossible, is usually interrupted by the man doing it.
