Can you use a WB O2 input into the GM ECM?

If I can find a Megasquirt at a reasonable price I would certainly try it, I have wanted to for a few years. I was going to fuel inject one of my dune buggies, was going to build an old D or L Jetronic system but just never got around to it.
I have all the parts and good FI engine cores.
I'm not sure about wide band O2 on the GM ECM? I am still searching for how to program the darn thing. I can find lots of BIN files with mods that have been done by others, but just not the logic or program that translates the binary into something like, "add more fuel at this RPM and vacuum" etc. I'll figure it out eventually.
I am currently building a WIN95 or 98 machine, boy that's fun, so I can run my old DOS based EPROM programmer. Sure glad I kept all my old Windows software...once a nerd, always a nerd.
The hardest part is finding a 486 machine...ha ha.
