Hey Jason,
Thank you for the idea. I had gone through the CD. There are about 7 files on it. A folder for Ford, one for GM and one for Import. Only the Ford one has anything, but it's all just shortcuts to the original owner's desktop Icons (I think). Each file is like 2KB and I get an error message when I hit one.
Then there are the instructions (that work fine), the Help file (works fine, but is limited - that Porsche-tuning site is much better than the instructions anyhow) and that's about it. I think because I cannot load the initial file you're supposed to (and have stuff on the desktop, etc), I'm stuck. It might be analogous to having a Word document you want to edit, but not having MS Office installed on the computer. The remaining couple of icons don't do anything (I can't open them. It says the computer doesnt recognize the file type and wants to look online for it. I ran the file type through MS's file searcher thing and it didnt find it there).
The original owner had downloaded some weird MAF files (MR2, Supra, etc) and put them in the Ford file. I don't think the CD came like that, so it must be rewritable, and that means who knows what was done to that CD. DOH. The file in the MAFTuner's EPROM has out-voltages real small compared to the in-voltages (suggesting he had big injectors, I think).
I'm just gonna wait a bit [and try to dig a little more] and see if anyone has an idea of what's wrong. Next time I have the files open, I'll take notes of what exact messages I get and what the file types are (if not LIO) so I can relay them to this thread. Maybe seeing that will help.
Oh, and regarding that other thread where I noted this being your sub-forum: you got it right.

I consider this sub-forum to be your baby.
Thanks again Jason.
