Howdy, I've got an old Pro-M Maf-Tuner (from circa '03) and could use some software help with it. I got the unit used and I can see the file that's saved on it. All I want to do is load a stock 94-95 GT MAF curve into the unit. Then I can use the pots to tinker with it just a hair. That's all I need. Now when I go to use the software that came with it, I can see the old file loaded into the Tuner, but I can't seem to be able to save anything of my own. Nor can I access the transfer curve files (that should have been included on the CD, I think). The CD never prompted me for my OS or installed anything on my desktop (as the instructions say it should). I think the CD that comes with it is rewritable - I wonder if a PO overwrote the files. Y'all know I'm a real puter dummy, so I would really welcome any assistance you can offer (assume I know nothing - you will not offend me). Thank you.
