The software doesn't care what kind of induction system you have. The key is to connect to the ECM. You need to match your software to the ECM. That requires the correct data template for the firmware in the ECM. The ECM spits out a series of numbers. You need the correct data template to interpret what those numbers mean.

If you have a carb the computer is not controlling anything. To the best of my knowledge the 84 ECM has never been hacked. If you want efi you'll have to restore all original parts, or update to TPI, or LT1, and or newer.
In a nice way, I don't really understand what you're asking.

Oh OK, I do work on cars but I am new to this car modding world. This is my first performance car, The previous owner swapped out the crossfire engine to an edelbrock small block , So I thought maybe I would be able to scan the car and also tune it if I wanted to using a OBD software

Have you actually seen a ECM under the dash ?
It is typical with a carb swap to put it in the rubbish bin
If it was still in place and you could connect to it ; as the man said it would not tell you anything useful
because as it no longer has any function as far as engine operation goes

Does your SERVICE ENGINE SOON light come on when you turn on the ignition without starting the engine? The SES light is controlled by the ECM, so if that doesn't work then the ECM is probably not there or is not functional (or the bulb for the SES light has been removed).

I recall winALDL will datalog 1984 ECM. Most of us are correcting fueling by modifying the fuel tables in .bin. However with a carb nothing can be done.
The ECU for the 1984 has not been hacked and no def file exists so you would need to swap to a diff computer if you wish to change .bin settings in future with a EFI induction system.

If you are using a carburetor and a vacuum advance distributor, everything is controlled mechanically. Your "tuning" is controlled by adjusting the carburetor.
With an AFR gauge and wideband o2 sensor, it will help you adjust the carburetor perfectly.
